  • 00:00:03
    so hello and welcome to aw Summit Berlin
  • 00:00:06
    and I hope you had some great session so
  • 00:00:08
    far my name is conine Gonzalez I'm a
  • 00:00:10
    principal Solutions architect with AWS
  • 00:00:13
    and my name is Elina lek and I'm an
  • 00:00:15
    associate Solutions architect with AWS
  • 00:00:18
    right so today we're going to talk about
  • 00:00:20
    prompt engineering best practices for
  • 00:00:22
    large language models on Amazon Bedrock
  • 00:00:25
    so let's dive in we are going to start
  • 00:00:27
    by setting the scene a little bit then
  • 00:00:30
    then we are going to look at some useful
  • 00:00:31
    techniques that Elina will then give you
  • 00:00:35
    some examples for on how to apply to
  • 00:00:37
    anthropic Cloud which is one of our
  • 00:00:39
    favorite models we'll take a quick look
  • 00:00:42
    Beyond prompting and finally we'll give
  • 00:00:44
    you some resources that you can use when
  • 00:00:46
    you start your own prompt engineering
  • 00:00:49
    Journey so prompt engineering really is
  • 00:00:52
    a bit of an art form and um to
  • 00:00:55
    understand this let's take a look at
  • 00:00:56
    what a prompt really means a prompt is
  • 00:00:59
    the information you pass into a large
  • 00:01:00
    language model to get some kind of
  • 00:01:03
    response so you write some text which is
  • 00:01:05
    the prompt you put it into the large
  • 00:01:07
    language model and you get a res
  • 00:01:10
    response back and um this is a bit of an
  • 00:01:14
    uncertain science so far right if we
  • 00:01:16
    look at a traditional job like an
  • 00:01:19
    engineer Engineers they can depend on
  • 00:01:22
    the rules of physics um so they always
  • 00:01:25
    know what they're getting similarly
  • 00:01:27
    software Engineers as a software
  • 00:01:29
    engineer you can depend on some
  • 00:01:31
    syntactical and semantic rules and
  • 00:01:33
    everything is very precise but as a
  • 00:01:35
    prompt engineer you're a bit more like
  • 00:01:37
    an artist and you have to try out
  • 00:01:41
    different things find your way around be
  • 00:01:43
    creative which is a good thing so why am
  • 00:01:47
    I saying that let's take a look at a
  • 00:01:48
    simple example if the prompt is what is
  • 00:01:50
    10 + 10 you might get as a response 20
  • 00:01:54
    if you think this is a math problem but
  • 00:01:57
    you might also get something like 10
  • 00:01:59
    plus 10 is an addition problem so this
  • 00:02:02
    is more like a
  • 00:02:04
    classification answer right or you can
  • 00:02:06
    get something like Quant SDS Ms which is
  • 00:02:10
    it would be a translation use case so
  • 00:02:12
    one prompt three different
  • 00:02:15
    responses uh there are other ways you
  • 00:02:17
    can have fun with prompting for example
  • 00:02:19
    in this case we're instructing the model
  • 00:02:21
    to uh with uh the beginning phrase of
  • 00:02:24
    you are a high school physics teacher
  • 00:02:26
    answer questions in one sentence and
  • 00:02:29
    then we give in a question like explain
  • 00:02:32
    quantum entanglement and we get
  • 00:02:34
    something that makes sense from a point
  • 00:02:36
    of view of a high school teacher quantum
  • 00:02:37
    entanglement is a phenomenon in which
  • 00:02:39
    two or more particles y y y that sort of
  • 00:02:41
    thing but if we start slightly
  • 00:02:43
    differently by telling the model you are
  • 00:02:45
    an excited three-year-old who ate a lot
  • 00:02:47
    of sugar answer questions in one
  • 00:02:49
    sentence and give it the same question
  • 00:02:52
    explain quantum entanglement we get a
  • 00:02:54
    very different response woo woo bash bam
  • 00:02:58
    particles go Zippy zappy when they're
  • 00:02:59
    together together and even if you take
  • 00:03:00
    them really far apart they still know
  • 00:03:02
    what their friend is doing cuz they're
  • 00:03:04
    magic connected same question different
  • 00:03:08
    answers and the difference really comes
  • 00:03:10
    down to prompt
  • 00:03:12
    engineering so instructions matter and
  • 00:03:16
    um when you put together your own
  • 00:03:19
    prompts think about Clarity and
  • 00:03:22
    specificity here are two ways of
  • 00:03:25
    prompting one way is tell me a story
  • 00:03:26
    about chaos but there are so many ways
  • 00:03:29
    you could tell a story about cows or you
  • 00:03:31
    can be much more specific and clear tell
  • 00:03:33
    me a story about cows it should be
  • 00:03:35
    roughly 2,000 words long and appropriate
  • 00:03:37
    for 5th graders it should be
  • 00:03:38
    entertaining but with a moral message
  • 00:03:40
    about the value of loyalty make it
  • 00:03:42
    amazing and
  • 00:03:44
    memorable so the key Point here is just
  • 00:03:47
    like humans llms cannot read your mind
  • 00:03:50
    as prompt Engineers it is our job to
  • 00:03:54
    bring our mind into a text prompt that
  • 00:03:56
    tells the model how to behave so here
  • 00:03:59
    are some useful techniques that you can
  • 00:04:01
    use one of the earliest discovered
  • 00:04:04
    techniques is called onot prompting
  • 00:04:07
    which essentially boils down to giving
  • 00:04:08
    the model an example of what you're
  • 00:04:10
    looking for for example here we want to
  • 00:04:13
    generate airpod codes out of text so we
  • 00:04:17
    might start with an example of what we
  • 00:04:19
    are really looking for and the example
  • 00:04:20
    is I want to F fly from Los Angeles to
  • 00:04:22
    Miami provide the airpods code only and
  • 00:04:25
    we are already giving the expected
  • 00:04:27
    results for this particular example
  • 00:04:28
    which is l ax and Mia for those two um
  • 00:04:32
    airport codes and then we follow up with
  • 00:04:34
    the actual question we want some answer
  • 00:04:36
    for I want to fly from Dallas to San
  • 00:04:38
    Francisco we start the assistance
  • 00:04:40
    response with airport Cod and square
  • 00:04:43
    bracket and now the model knows exactly
  • 00:04:45
    what we're expecting and it completes
  • 00:04:47
    our sentence with DFW and SFO so this is
  • 00:04:50
    an example of oneshot prompting we give
  • 00:04:53
    the model one example and use that to
  • 00:04:57
    illustrate what we are looking for so
  • 00:04:59
    that the model is kind of guided into
  • 00:05:02
    giving us the the right kind of response
  • 00:05:04
    we uh response we're looking for you can
  • 00:05:07
    also do F short prompting and F short
  • 00:05:09
    prompting is what you would expect we
  • 00:05:11
    give it multiple examples for example in
  • 00:05:13
    this case we want to use a large
  • 00:05:15
    language model to classify tweets we
  • 00:05:18
    give it three different examples of
  • 00:05:20
    three different classifications that we
  • 00:05:21
    are looking for and then the fourth one
  • 00:05:23
    is the actual thing we wanted to do
  • 00:05:25
    where we are kind of pasting in some
  • 00:05:27
    tweet and then we get uh hopefully what
  • 00:05:29
    we are looking for because now we gave
  • 00:05:31
    it some really good examples that tell
  • 00:05:33
    the model what we what we
  • 00:05:36
    want you can
  • 00:05:38
    also use a technique called Chain of
  • 00:05:41
    Thought prompting so with Chain of
  • 00:05:44
    Thought prompting we want to make sure
  • 00:05:46
    that the model
  • 00:05:48
    really puts some energy into thinking
  • 00:05:51
    clearly and we can actually do this
  • 00:05:54
    really easily by telling it let's think
  • 00:05:56
    step by step so on the left hand side
  • 00:05:58
    you see an example example where we're
  • 00:06:00
    asking the model to solve a puzzle for
  • 00:06:02
    us a juggler can juggle 16 balls half of
  • 00:06:05
    the balls are golf balls and half of
  • 00:06:06
    them are blue blah blah blah and we're
  • 00:06:08
    getting a wrong answer because the model
  • 00:06:11
    gets kind of confused right but when we
  • 00:06:13
    are adding the simple sentence let's
  • 00:06:15
    think step by step now we're getting a
  • 00:06:17
    good answer out of the same model this
  • 00:06:20
    is a surprising trick that researchers
  • 00:06:22
    found out in the early days of llms and
  • 00:06:25
    it still works so think about when
  • 00:06:27
    you're not getting the right results ask
  • 00:06:29
    simply ask it to to uh think step by
  • 00:06:32
    step uh which is called Chain of Thought
  • 00:06:35
    prompting and now we can combine these
  • 00:06:38
    two things we can use examples and use
  • 00:06:41
    that example to teach the model how to
  • 00:06:44
    think step by step so left hand side
  • 00:06:47
    again uh an example that doesn't work we
  • 00:06:49
    are using Roger has five tennis balls
  • 00:06:52
    that's the the the first puzzle and
  • 00:06:54
    we're giving it the answer we want like
  • 00:06:56
    the answer is 11 but the model doesn't
  • 00:06:58
    quite understand how to get to that
  • 00:07:00
    answer right on the right hand side same
  • 00:07:04
    example but now in our example answer
  • 00:07:07
    we're kind of telling we're guiding the
  • 00:07:09
    model along our thinking process for
  • 00:07:12
    example in this tennis ball example the
  • 00:07:13
    thinking process is Roger started with
  • 00:07:16
    five balls two cans of three tennis
  • 00:07:17
    balls each is six tennis balls 5 + 6
  • 00:07:20
    equal 11 the answer is 11 so we adding
  • 00:07:23
    the thinking process which is implicit
  • 00:07:26
    Chain of Thought prompting and now we we
  • 00:07:28
    can get when we paste the actual
  • 00:07:30
    question that we want some answer for
  • 00:07:32
    like the cafeteria had 23 apples and so
  • 00:07:34
    on now we're getting the right model
  • 00:07:36
    output including the thinking process
  • 00:07:38
    which also has the capability for us to
  • 00:07:40
    debug what the model was thinking so it
  • 00:07:43
    tells us how it arrived at the answer
  • 00:07:45
    and surprise it gets to the right answer
  • 00:07:48
    because it knows how to think so when
  • 00:07:51
    you craft examples think about using
  • 00:07:54
    examples where you're actually telling
  • 00:07:56
    the model how exactly to
  • 00:07:58
    think so so with those initial examples
  • 00:08:02
    out of way the way let's get way more
  • 00:08:04
    practical and I'd like to introduce you
  • 00:08:07
    to Elina who is going to show you how to
  • 00:08:09
    prompt anthropic cloth which is my
  • 00:08:11
    personal favorite model
  • 00:08:13
    here so are you looking for some
  • 00:08:16
    concrete examples of the best practices
  • 00:08:19
    that we recommend impr prompt
  • 00:08:21
    engineering this section will uh cover
  • 00:08:25
    nine best practices and I would actually
  • 00:08:29
    start was introducing myself so my name
  • 00:08:31
    is Elina lassik and I joined AWS two
  • 00:08:34
    years ago and well I wanted to follow my
  • 00:08:37
    passion in scaling ideas as well as
  • 00:08:39
    built machine learning products I have
  • 00:08:42
    had an honor to work with customers from
  • 00:08:44
    different segments of different company
  • 00:08:46
    sizes and they all have had one
  • 00:08:51
    question that question was what is that
  • 00:08:55
    model that I should start experimenting
  • 00:08:58
    with in many cases the answer was indeed
  • 00:09:01
    entropic models that is exactly why we
  • 00:09:04
    have decided to bring concrete examples
  • 00:09:06
    of prompt engineering with entropic
  • 00:09:10
    clot I would like to start
  • 00:09:15
    with introducing you to the latest
  • 00:09:17
    edition of entropic CLA model family
  • 00:09:21
    namely clae 3 with the corresponding API
  • 00:09:25
    namely messages API an important hint to
  • 00:09:28
    prompt engine engering is to think a
  • 00:09:31
    step back and consider how the llms were
  • 00:09:35
    trained in the case of CLA we have the
  • 00:09:38
    alternating dialogue between user and
  • 00:09:42
    assistant that is built in the form of
  • 00:09:45
    history of the conversation which in
  • 00:09:47
    this case would be
  • 00:09:49
    messages and that is an important hint
  • 00:09:51
    for us to also consider once we are
  • 00:09:53
    doing prompt
  • 00:09:55
    engineering so if you have previously
  • 00:09:58
    used uh models lower than three then you
  • 00:10:01
    would uh see something like completion
  • 00:10:03
    API and if you would like to use clot
  • 00:10:06
    three models you would need to use
  • 00:10:08
    messages API and on the right hand side
  • 00:10:11
    right now you can see the example of how
  • 00:10:13
    the input into messages API can look
  • 00:10:15
    like and that is following this idea of
  • 00:10:18
    the alternating dialogue between user
  • 00:10:20
    and assistant that are given as rowes
  • 00:10:23
    within messages and we also have
  • 00:10:25
    something called system prompt that we
  • 00:10:27
    will cover in several minutes minutes in
  • 00:10:29
    more
  • 00:10:31
    detail now I would like to start with
  • 00:10:34
    the best practice number one and you
  • 00:10:36
    won't be surprised by it because it is
  • 00:10:40
    the tip on indeed being very clear and
  • 00:10:43
    Direct in our
  • 00:10:45
    prompts clot definitely responds better
  • 00:10:48
    to clear and direct
  • 00:10:50
    instructions at the same time I am
  • 00:10:53
    personally still a big victim of using
  • 00:10:55
    you know this polite words like could
  • 00:10:57
    you please
  • 00:10:59
    claw can we consider and uh similar
  • 00:11:03
    things that are rather wake in case of
  • 00:11:06
    prompt engineering so it is helpful for
  • 00:11:09
    me to always recall the principle of
  • 00:11:11
    clarity here as well as something that
  • 00:11:14
    we could consider as rubber duck
  • 00:11:16
    principle in software development but in
  • 00:11:19
    case of building um LMS LM applications
  • 00:11:23
    we can think about Golden Rule of clear
  • 00:11:26
    prompting the idea here is that once we
  • 00:11:28
    are in doubt we can go with our prompt
  • 00:11:31
    to our friend or to our colleague and
  • 00:11:33
    indeed ask them to follow something that
  • 00:11:37
    we are pretty much prompting for if they
  • 00:11:40
    are able to follow llm is also likely to
  • 00:11:43
    follow on the right right uh hand side
  • 00:11:46
    of the slide you can see our example and
  • 00:11:49
    well if we are willing to have a hio on
  • 00:11:52
    a certain topic and we would like to
  • 00:11:54
    skip the Preamble that is in the form of
  • 00:11:56
    well here is this hu the idea would be
  • 00:11:59
    to indeed be very clear in that and
  • 00:12:01
    instruct the model to skip this
  • 00:12:04
    Preamble so having the clarity in mind
  • 00:12:07
    we would proceed and do you recall
  • 00:12:10
    Constantine's example on um the
  • 00:12:12
    difference between explanations of
  • 00:12:16
    quantum entanglement between PhD student
  • 00:12:19
    and this over glucose
  • 00:12:21
    kit well the idea here is indeed to
  • 00:12:25
    utilize
  • 00:12:26
    roles uh also known as Ro prompt
  • 00:12:30
    and it is helping us to give the context
  • 00:12:33
    to claw to understand what role it
  • 00:12:35
    should
  • 00:12:37
    inhibit it won't be big secret that LMS
  • 00:12:40
    are not the best ones when it comes to
  • 00:12:42
    math they generally don't calculate
  • 00:12:45
    responses they generate responses at the
  • 00:12:48
    same time when we're using Ro prompting
  • 00:12:51
    we can help CLA to be more close to math
  • 00:12:54
    world or the world of solving
  • 00:12:57
    puzzles thus imp proving
  • 00:13:01
    accuracy at the same time how I'm
  • 00:13:04
    thinking about role prompting is the
  • 00:13:05
    sort of dress code so if we are thinking
  • 00:13:08
    about the parties that we should join we
  • 00:13:09
    are checking what is the style that is
  • 00:13:11
    expected there should it be casual
  • 00:13:13
    should it be formal that is also the
  • 00:13:15
    concept that we can utilize here and
  • 00:13:18
    think about this way of speaking to llms
  • 00:13:22
    that can change the tone and potential
  • 00:13:25
    style of the conversation that we will
  • 00:13:27
    be going through and on on the right
  • 00:13:29
    hand side of the slide you can see the
  • 00:13:31
    example of the puzzle that without any
  • 00:13:34
    additional role is likely to be solved
  • 00:13:37
    in a wrong way however the simple trick
  • 00:13:40
    of saying you are a master solver of all
  • 00:13:43
    puzzles in the world can help to improve
  • 00:13:45
    the
  • 00:13:48
    accuracy Constantine has introduced us
  • 00:13:50
    to the concept of fusure prompting and
  • 00:13:54
    in context of entropic models how this
  • 00:13:57
    can be put into action
  • 00:13:59
    well we can use examples and we see that
  • 00:14:03
    examples are indeed very effective in
  • 00:14:06
    generally speaking it is also very
  • 00:14:08
    helpful to consider examples that are
  • 00:14:11
    coming from different edge
  • 00:14:14
    cases we know that the more examples the
  • 00:14:18
    better the response is of course with
  • 00:14:20
    certain trade-offs that we can see when
  • 00:14:22
    it comes to the number of tokens and on
  • 00:14:25
    the slide you can see the ex you can see
  • 00:14:27
    the example and if our goal is indeed to
  • 00:14:30
    get the concrete name name and surname
  • 00:14:34
    of the author of a certain passage
  • 00:14:35
    without anything extra we can pretty
  • 00:14:38
    much prompt llm to give us exactly this
  • 00:14:43
    by using
  • 00:14:46
    example we have also thought about uh
  • 00:14:48
    the concept of Chain of Thought and how
  • 00:14:50
    to use it with claw and it works in a
  • 00:14:54
    way that we can just give clot time to
  • 00:14:57
    think if we would look into the example
  • 00:15:00
    of the input that we are passing into
  • 00:15:03
    llm we are using thinking as our XML TX
  • 00:15:08
    and we are letting the model to put
  • 00:15:11
    chain of thought into action and
  • 00:15:13
    consider this stinking stepbystep
  • 00:15:15
    process within thinking
  • 00:15:17
    steps how the output looks like
  • 00:15:22
    Well normally we would get the response
  • 00:15:25
    from the assistant that would start with
  • 00:15:27
    thinking and then with answering and
  • 00:15:29
    what is interesting is that exactly
  • 00:15:31
    something that we would find within
  • 00:15:33
    thinking XML Tex is helpful for us to
  • 00:15:36
    debug or to
  • 00:15:39
    troubleshoot you can already see here
  • 00:15:42
    some peculiar feature of CLA models what
  • 00:15:46
    is it well it is indeed using XML Tex
  • 00:15:49
    and that is the tip number five that we
  • 00:15:51
    would like to
  • 00:15:53
    give XML texts are helpful to structure
  • 00:15:57
    the prompts that we are sending to l
  • 00:15:59
    LS
  • 00:16:01
    and once we would like to have certain
  • 00:16:03
    sections within our prompts that is
  • 00:16:05
    where XML text can help us to have the
  • 00:16:08
    structure if we would look into the
  • 00:16:11
    example of us willing to have the email
  • 00:16:14
    of well if we are the person that should
  • 00:16:16
    ask our team to show up at some early uh
  • 00:16:20
    time of the day as uh 6:00 a.m. and
  • 00:16:23
    draft this email in some formal response
  • 00:16:25
    if we will just throw this into model in
  • 00:16:27
    this form of well just show up at 600
  • 00:16:29
    a.m. because I say so the model can
  • 00:16:33
    sometimes misjudge and not understand
  • 00:16:36
    that we are actually speaking about the
  • 00:16:38
    email that we would like to send to uh
  • 00:16:40
    to our team and it will start responding
  • 00:16:42
    as if it was sent to
  • 00:16:45
    it and once we are introducing XML TXS
  • 00:16:49
    of well here is the context of the email
  • 00:16:52
    we can get the response that we were
  • 00:16:53
    looking
  • 00:16:55
    for we can already see here that we are
  • 00:16:59
    explicitly talking about the output that
  • 00:17:01
    we are willing to see and indeed we can
  • 00:17:04
    help clot with this output by
  • 00:17:08
    speaking and prefilling of our assistant
  • 00:17:12
    for getting the output that we are
  • 00:17:16
    expecting how can it be done well it is
  • 00:17:18
    done very often in the form of preing
  • 00:17:22
    within assistant so very common use case
  • 00:17:25
    that we observe from our customers is
  • 00:17:27
    some Json files or some y files that are
  • 00:17:30
    having certain structure and we would
  • 00:17:31
    like to get exactly files in this
  • 00:17:33
    structure once we are getting the
  • 00:17:35
    response from llms and we are here in
  • 00:17:38
    the example preing for Json files just
  • 00:17:41
    by using a first curly bracket which is
  • 00:17:44
    of course incre increasing the
  • 00:17:46
    likelihood of us getting Json file as
  • 00:17:48
    the
  • 00:17:51
    response another very popular feature of
  • 00:17:54
    cloud models is Big context base of two
  • 00:17:59
    100,000
  • 00:18:01
    tokens we would really encourage you to
  • 00:18:03
    use this context base efficiently
  • 00:18:06
    because well what is 200,000 tokens it
  • 00:18:10
    can be a
  • 00:18:11
    book it can be a book that we will just
  • 00:18:14
    pass to llm
  • 00:18:17
    directly and to utilize this way of uh
  • 00:18:22
    using context base effectively what we
  • 00:18:24
    recommend is again to consider XML text
  • 00:18:27
    to separate what we are passing and
  • 00:18:31
    instructions we would also think about
  • 00:18:34
    using quotes for us to have the response
  • 00:18:37
    that is closer to the content that we
  • 00:18:39
    are passing as well as well as it also
  • 00:18:42
    works with us as humans we can prompt
  • 00:18:45
    for Claude to read the document
  • 00:18:48
    carefully because it will be asked
  • 00:18:50
    questions
  • 00:18:51
    later and the last but not the least tip
  • 00:18:54
    here is again to reconsider fusure
  • 00:18:57
    prompting and to use the
  • 00:18:59
    questions and answer pairs in the form
  • 00:19:01
    of
  • 00:19:05
    examples when it comes to the prompts
  • 00:19:07
    that are having certain steps in between
  • 00:19:11
    what is also helpful is to consider
  • 00:19:13
    prompt
  • 00:19:14
    chaining I will uh uh jump straight into
  • 00:19:17
    the example so if we would be having the
  • 00:19:20
    task of extracting the names from
  • 00:19:23
    certain text and we would like to have
  • 00:19:25
    them in alphabetical order we can
  • 00:19:27
    definitely start with was saying well
  • 00:19:29
    just extract those names in alphabetical
  • 00:19:31
    order or we can consider splitting this
  • 00:19:34
    into two
  • 00:19:35
    prompts so that in the first one we
  • 00:19:38
    would have the extraction of names first
  • 00:19:42
    and in the second prompt we would have
  • 00:19:45
    them
  • 00:19:47
    alphabetized with this way of chaining
  • 00:19:51
    prompts we are increasing the likelihood
  • 00:19:53
    of getting the output that we are
  • 00:19:55
    looking for and you can also recall here
  • 00:19:58
    the example of prefilling the assistant
  • 00:20:00
    was this names XML
  • 00:20:03
    tag so the last but not the least tip
  • 00:20:07
    from us today would be on using
  • 00:20:09
    structured prom templates if we are
  • 00:20:12
    considering the example with the SL
  • 00:20:14
    documents that can be as I mentioned
  • 00:20:17
    books it is very helpful to put this
  • 00:20:20
    input Data before our
  • 00:20:24
    instruction if we are looking into a
  • 00:20:26
    different example of using certain input
  • 00:20:30
    data that is having the effect of
  • 00:20:33
    iteration or certain um dictionary or
  • 00:20:36
    List uh and in this case in the example
  • 00:20:38
    it would be the um types of different
  • 00:20:42
    animals the idea here would be to also
  • 00:20:44
    structure our uh prompt in a way that we
  • 00:20:47
    would have the iteration uh within this
  • 00:20:49
    input data and thus our output would be
  • 00:20:53
    having also different types of animals
  • 00:20:57
    put into it
  • 00:21:00
    so we have started talking here about
  • 00:21:02
    some structures that we are giving to
  • 00:21:03
    our prompts and now we would like to
  • 00:21:07
    cover something different we would like
  • 00:21:10
    to cover system prompts so those prompts
  • 00:21:13
    that are going into llm as initial ones
  • 00:21:18
    those ones that are setting the scene
  • 00:21:20
    for the
  • 00:21:22
    conversation you have already seen
  • 00:21:24
    different beats and pieces of them
  • 00:21:26
    within our previous best practices
  • 00:21:29
    at the same time now we would like to
  • 00:21:30
    bring them all together into one system
  • 00:21:33
    prompt template so to say you will see
  • 00:21:36
    nine sections here and again you can
  • 00:21:39
    definitely avoid using some of them if
  • 00:21:41
    they don't if that doesn't fit uh your
  • 00:21:43
    use case at the same time what we uh
  • 00:21:46
    strongly recommend here is for you to
  • 00:21:48
    follow the order that we are having
  • 00:21:52
    here I will jump straight into the
  • 00:21:55
    example of how this system uh prompt can
  • 00:21:58
    be built and our use case would be to
  • 00:22:01
    have a certain career coach that would
  • 00:22:03
    be helping users with their career
  • 00:22:06
    aspirations so we start with the element
  • 00:22:09
    of our system uh prom template which is
  • 00:22:12
    in giving the
  • 00:22:13
    role so here the F first things first we
  • 00:22:16
    are uh explicitly saying that uh you
  • 00:22:19
    will be acting as an AI career coach
  • 00:22:22
    with certain name and we would probably
  • 00:22:24
    like to maintain the same name for this
  • 00:22:26
    career coach during our conversation
  • 00:22:29
    and at the same time what is your goal
  • 00:22:31
    your goal is to give career advice to
  • 00:22:33
    users the second element would be here
  • 00:22:36
    to use certain tone context or style of
  • 00:22:39
    the conversation so you should maintain
  • 00:22:41
    a friendly customer service
  • 00:22:45
    tone the third tip is utilizing the
  • 00:22:48
    context base and is passing certain
  • 00:22:51
    background data for our career coach to
  • 00:22:54
    process and again it can be included
  • 00:22:57
    within XML tax of in this case
  • 00:23:01
    guide the next element would be to give
  • 00:23:05
    more detailed in task description as
  • 00:23:08
    well as certain rules and here uh you
  • 00:23:10
    can also pay attention to how we are
  • 00:23:12
    letting Claud say that well if you don't
  • 00:23:15
    know you can tell that as well as uh if
  • 00:23:19
    uh someone is asking something that is
  • 00:23:20
    not relevant to the topic you can
  • 00:23:22
    also say that well I am here only to
  • 00:23:25
    give career advice
  • 00:23:28
    The Next Step would be to use
  • 00:23:31
    examples on potential also common um
  • 00:23:34
    common uh cases as well as edge cases as
  • 00:23:37
    well as uh give some immediate data in
  • 00:23:40
    this case it can be probably the history
  • 00:23:42
    of the conversation or for example the
  • 00:23:44
    information of the profile of the user
  • 00:23:45
    that our career coach is talking to the
  • 00:23:49
    seventh step would be to indeed
  • 00:23:51
    reiterate on what is the immediate task
  • 00:23:54
    here and allow clot or another llm of
  • 00:23:58
    your choice to think step by step and
  • 00:24:01
    even take a deep breath because we've
  • 00:24:03
    heard it to work efficiently from
  • 00:24:05
    scientific
  • 00:24:07
    papers as the last but not the least
  • 00:24:09
    element here would be to set certain
  • 00:24:14
    output and again we are utilizing XML
  • 00:24:17
    tags here and that has been the
  • 00:24:20
    suggested elements of our system prom
  • 00:24:22
    template let me bring them all together
  • 00:24:25
    for
  • 00:24:26
    you and would be the overview and I see
  • 00:24:30
    that some of you are willing to take the
  • 00:24:34
    picture so now we are having the system
  • 00:24:37
    promt
  • 00:24:38
    template how can we move even further
  • 00:24:41
    and how can we get even more
  • 00:24:44
    professional and consider what can be
  • 00:24:46
    done after we have gone through
  • 00:24:49
    prompting well we do consider prompt
  • 00:24:53
    engineering to be an art form at the
  • 00:24:56
    same time with Constantine we have
  • 00:24:57
    decided to try to add science to this
  • 00:25:00
    art form and with simple steps help to
  • 00:25:04
    make art work for your use
  • 00:25:07
    cases so the first step would normally
  • 00:25:10
    in our journey would be to of course
  • 00:25:13
    understand the use case as well as
  • 00:25:15
    develop certain test
  • 00:25:17
    cases I live in Munich so I will walk
  • 00:25:20
    you through the example that would be
  • 00:25:22
    helping me with understanding Bavarian
  • 00:25:24
    culture or it can be also the culture of
  • 00:25:26
    b vonach um so let's think about this
  • 00:25:28
    use case and um develop the test the
  • 00:25:32
    test use case that well maybe I will be
  • 00:25:35
    asking about certain dishes that are
  • 00:25:37
    relevant to a certain area of
  • 00:25:41
    Germany thus my um preliminary prompt
  • 00:25:46
    would be on cooking a certain dish so
  • 00:25:48
    how do I how do I make haish P or how do
  • 00:25:52
    I cook o
  • 00:25:54
    BDA and of course afterwards I'm going
  • 00:25:57
    into the ative phases with
  • 00:26:01
    evaluations that would be then going
  • 00:26:03
    into Loops in this case the first Loop
  • 00:26:06
    would be for example to consider adding
  • 00:26:08
    the role such as well you are an
  • 00:26:10
    experienced ethnographer or you an
  • 00:26:12
    experienced
  • 00:26:13
    cook and thus we will be refining The
  • 00:26:16
    Prompt that will be coming to the point
  • 00:26:18
    of being polished to the extent that it
  • 00:26:21
    fulfills our
  • 00:26:23
    goals a tricky part here is indeed in
  • 00:26:27
    setting evaluation
  • 00:26:30
    and if we have some test cases that are
  • 00:26:33
    closed ended questions having yes or no
  • 00:26:36
    answer it is possible to evaluate that
  • 00:26:40
    was not um many issues but if it is
  • 00:26:43
    open-ended
  • 00:26:45
    question let's again look into the
  • 00:26:47
    example of K sple and if we would have
  • 00:26:50
    again this uh first prompt of how do I
  • 00:26:52
    make his we would get of course LM
  • 00:26:55
    response that would be telling us what
  • 00:26:57
    elements do and what ingredients we
  • 00:26:59
    would have in our dish what is
  • 00:27:01
    interesting here is that we can utilize
  • 00:27:05
    rubrics and Define what we would like to
  • 00:27:07
    include in the response for it to be
  • 00:27:09
    evaluated as positive or negative so I
  • 00:27:12
    would prefer to have certain ingredients
  • 00:27:15
    and once we have the response that
  • 00:27:18
    fulfills the criteria we would have the
  • 00:27:21
    uh positive result and we would be
  • 00:27:23
    knowing that well our prompt engineering
  • 00:27:26
    and LM response were indeed true for
  • 00:27:31
    us many customers come to us
  • 00:27:34
    and uh ask about uh what can be done for
  • 00:27:38
    reducing hallucinations and that is also
  • 00:27:40
    something that
  • 00:27:42
    uh we would like to uh encourage you to
  • 00:27:45
    do with uh dealing with gallins and what
  • 00:27:49
    can be done is indeed to give lm's
  • 00:27:51
    permission to say I don't
  • 00:27:53
    know as well as answer only if it is
  • 00:27:56
    very confident in its response
  • 00:28:00
    it is also possible to ask about uh
  • 00:28:03
    relevant quotes from the context that we
  • 00:28:06
    have passed and once our context is
  • 00:28:09
    growing once we are having certain
  • 00:28:12
    iterations and changes to the context
  • 00:28:14
    that we would still like to pass to an
  • 00:28:17
    llm we can consider using something
  • 00:28:20
    called retrieval augmented
  • 00:28:23
    generation retrieval augmented
  • 00:28:26
    generation would look in a certain way
  • 00:28:28
    way that instead of having the typical
  • 00:28:31
    flow of user asking the question from
  • 00:28:33
    the LM and getting the the the response
  • 00:28:36
    we would be also passing a certain
  • 00:28:39
    additional
  • 00:28:40
    context that would be in the form of
  • 00:28:43
    dynamically changing knowledge basis or
  • 00:28:45
    certain
  • 00:28:47
    internal sources we can consider product
  • 00:28:50
    descriptions we can consider fq pages
  • 00:28:53
    and in this way the flow would be
  • 00:28:56
    changing in a way that all all the in
  • 00:28:59
    all the documents um would be passed
  • 00:29:02
    into some uh Vector database and once
  • 00:29:05
    the user is sending the question we
  • 00:29:08
    first get everything relevant from the
  • 00:29:12
    context let's say three uh pieces of um
  • 00:29:16
    certain uh fq description and then that
  • 00:29:19
    would be passed as the context together
  • 00:29:21
    with the question to llm thus creating
  • 00:29:25
    the answer for
  • 00:29:26
    us and while the are different uh moving
  • 00:29:29
    blocks in this architecture so
  • 00:29:32
    Constantine shall we help the audience
  • 00:29:35
    to consider different tools for building
  • 00:29:37
    uh retrieval augmented generation sure
  • 00:29:39
    thank you Elina so I like to think of
  • 00:29:42
    retrieval augmented Generation Um
  • 00:29:44
    similar to giving the llm a cheat sheet
  • 00:29:48
    right so as you know from school
  • 00:29:50
    probably uh when you don't know the
  • 00:29:52
    answer you tend to make up something uh
  • 00:29:54
    but if you have a cheat sheet it's very
  • 00:29:56
    easy to solve the question so what we're
  • 00:29:58
    really doing here is we're using the
  • 00:29:59
    knowledge base and some way of searching
  • 00:30:01
    the knowledge base like a vector
  • 00:30:03
    database or search engine or anything
  • 00:30:05
    you can use to provide the relevant
  • 00:30:07
    information and then we generate a cheat
  • 00:30:09
    sheet that we inject into the prompt as
  • 00:30:12
    as part of the context so that increases
  • 00:30:14
    the likelihood of the llm giving the
  • 00:30:16
    right answer because now it has all the
  • 00:30:18
    data it needs um you can um set up this
  • 00:30:22
    thing on your own by putting together
  • 00:30:25
    the components like the knowledge base
  • 00:30:27
    and setting up the or frustration on all
  • 00:30:29
    all that um that is fun but it also can
  • 00:30:32
    become old quickly especially when your
  • 00:30:35
    uh manager is brething down your neck
  • 00:30:36
    and say hey when is my solution ready
  • 00:30:38
    right so um our job at AWS is to make it
  • 00:30:41
    easy for you so first um while ago we
  • 00:30:44
    introduced Amazon Bedrock which is makes
  • 00:30:46
    it super easy to use a selection of
  • 00:30:48
    different llms um with an easy to ous
  • 00:30:51
    API in a secure way uh so that you stay
  • 00:30:54
    in control with your data and then we
  • 00:30:56
    added an an additional feature called
  • 00:30:58
    knowledge bases for Amazon Bedrock which
  • 00:31:00
    essentially gives you the retrieval
  • 00:31:02
    augmented generation architecture that
  • 00:31:03
    we uh looked at before as a ready to use
  • 00:31:07
    feature of Bedrock so all you need to do
  • 00:31:09
    is you bring your knowledge base in the
  • 00:31:11
    form of some sort of document you can in
  • 00:31:14
    you can import them into knowledge bases
  • 00:31:17
    for Amazon Bedrock you can choose which
  • 00:31:20
    of the vector search engines or
  • 00:31:22
    databases you would like to use from a
  • 00:31:24
    collection of choices you can choose
  • 00:31:26
    which uh llm you want to use as part of
  • 00:31:29
    your architecture and then Bedrock does
  • 00:31:31
    everything else automatically for you
  • 00:31:33
    including the prompt engineering bit um
  • 00:31:36
    if you want to control the prompt prompt
  • 00:31:38
    you can actually add your own um
  • 00:31:40
    variation of the prompt or you can
  • 00:31:42
    simply use what is shipped inside Amazon
  • 00:31:44
    Bedrock so bedrock and knowledge bases
  • 00:31:47
    make it really easy for you to build
  • 00:31:48
    your own knowledge base uh architecture
  • 00:31:51
    your own retrieval augmented generation
  • 00:31:53
    and retrieval augmented generation is is
  • 00:31:55
    one of the most popular use cases we see
  • 00:31:57
    with customer
  • 00:31:58
    because it generates uh immediate um
  • 00:32:01
    value for your business no more
  • 00:32:03
    searching and hunting through long
  • 00:32:05
    product manuals long uh boring
  • 00:32:07
    documentation you can simply ask
  • 00:32:09
    questions get relevant answers that are
  • 00:32:11
    right from your documentation including
  • 00:32:13
    citations so that you know that you're
  • 00:32:15
    getting good answers
  • 00:32:18
    here another thing that our customers
  • 00:32:20
    like to use with llms is called agents
  • 00:32:22
    so agents and function calling um how
  • 00:32:25
    does it work well um instead of just
  • 00:32:28
    injecting documents from a search engine
  • 00:32:31
    like with retrieval augmented generation
  • 00:32:33
    you can go one step further and you can
  • 00:32:35
    tell the model hey model CLA in this
  • 00:32:38
    case right you actually have access to
  • 00:32:40
    some tools let me explain you how those
  • 00:32:42
    tools work and then you're giving it
  • 00:32:44
    like a prompt engineered version of an
  • 00:32:46
    API specification so what you're doing
  • 00:32:49
    here is um you're telling the model you
  • 00:32:51
    have access to a Weather Service you
  • 00:32:53
    have access to a Wikipedia you have
  • 00:32:54
    access to some other tool that you
  • 00:32:56
    choose how it works and then claw does
  • 00:32:59
    not really call those tools on its own
  • 00:33:02
    but it will tell you hey I would like to
  • 00:33:04
    use a Weather Service now with this
  • 00:33:06
    parameters and then you can engineer or
  • 00:33:08
    you can set up the actual function call
  • 00:33:11
    do the operation and give the result
  • 00:33:14
    back as part of the prompt so how does
  • 00:33:16
    it work well uh first of all you start
  • 00:33:19
    by putting together a prompt where you
  • 00:33:21
    describe to the model here are the tools
  • 00:33:23
    you have access to um think of this as
  • 00:33:26
    you put together your answer put them
  • 00:33:28
    into Claude as part of the prompt Claud
  • 00:33:30
    now decides whether it can answer the
  • 00:33:32
    question right away or whether it would
  • 00:33:34
    like to use one of these functions that
  • 00:33:36
    you gave it and in the case of no it
  • 00:33:38
    will probably answer with some
  • 00:33:41
    definitive answer like I don't know or
  • 00:33:43
    it says Okay I want to use those tools
  • 00:33:45
    and clot will actually output the
  • 00:33:47
    function call in the specification that
  • 00:33:50
    you told it so if you told it that
  • 00:33:52
    please use XML calls that are called
  • 00:33:54
    function calls invoke with the
  • 00:33:55
    parameters here and there it'll give you
  • 00:33:57
    the kind of XML that you expect and now
  • 00:34:00
    you can go and execute that so the
  • 00:34:02
    execution step looks like this in more
  • 00:34:04
    detail right so you get this function
  • 00:34:06
    call XML from CLA as a response you know
  • 00:34:09
    you can actually grab or you can you can
  • 00:34:11
    detect this with your traditional code
  • 00:34:12
    like a Lambda function hey Cloud wants
  • 00:34:14
    to call something you can use this XML
  • 00:34:18
    maybe validate it and then you actually
  • 00:34:20
    Implement your own client um in your own
  • 00:34:23
    code could be Lambda could be a
  • 00:34:25
    container whatever that does the
  • 00:34:27
    function call in this example it would
  • 00:34:28
    call the weather function and then you
  • 00:34:31
    inject the results back uh into their
  • 00:34:34
    own uh XML text like function results
  • 00:34:36
    and then you send the whole thing back
  • 00:34:38
    to clo right the system prompt the user
  • 00:34:41
    question the function call the function
  • 00:34:43
    results and then you let Claud decide
  • 00:34:46
    what to do next and then Claud sees oh I
  • 00:34:48
    have everything I know I want I have the
  • 00:34:50
    weather data I can now give a great
  • 00:34:52
    answer and then you get your answer so
  • 00:34:55
    that's how you implement your own
  • 00:34:56
    functions in the context of a large
  • 00:34:58
    language model by telling the model
  • 00:35:00
    these are the functions you can use
  • 00:35:02
    giving it an API specification in an
  • 00:35:04
    easy to use language such as XML Tex and
  • 00:35:07
    then you let the model decide when to
  • 00:35:09
    use which tool you are in control in how
  • 00:35:12
    you implement those tool those function
  • 00:35:14
    calls and then you give everything back
  • 00:35:15
    for the model to process and give a
  • 00:35:17
    definitive
  • 00:35:19
    answer now when you implement something
  • 00:35:21
    like this um explain the function
  • 00:35:25
    capabilities in great detail right this
  • 00:35:27
    is the same as explaining to a human
  • 00:35:30
    like your colleague how does this API
  • 00:35:32
    work um you can also provide a diverse
  • 00:35:35
    set of examples here is an example of
  • 00:35:37
    using this call to do X here is an
  • 00:35:39
    example of how the parameters might look
  • 00:35:40
    like for y and everything and um you can
  • 00:35:43
    actually use the stop tag or the end tag
  • 00:35:47
    of your function spec specification a
  • 00:35:49
    stop sequence which tells the Bedrock
  • 00:35:52
    service okay stop after this um sequence
  • 00:35:55
    here after this XML tag here because now
  • 00:35:58
    the XML part is over and you have a
  • 00:36:00
    definitive stop uh condition and um if
  • 00:36:04
    if it's if you're not getting reliable
  • 00:36:06
    results think about the prompt chaining
  • 00:36:09
    tip in the beginning don't make your
  • 00:36:11
    task too complicated break them down
  • 00:36:13
    into simple function calls and then do
  • 00:36:16
    them one by
  • 00:36:17
    one so here's an example on how it looks
  • 00:36:20
    in practice um this is how you would
  • 00:36:22
    describe the tool tool description tool
  • 00:36:25
    name is get weather uh this is the
  • 00:36:27
    descript destion um these are the
  • 00:36:29
    parameters location which is a string
  • 00:36:31
    you can actually add type declarations
  • 00:36:33
    there as well and all that stuff and and
  • 00:36:35
    you can use that as part of your system
  • 00:36:37
    prompt again you can do this all on your
  • 00:36:40
    own and it's fun the first time um but
  • 00:36:42
    you can also use a feature called agents
  • 00:36:45
    for Amazon Bedrock which allow you to
  • 00:36:47
    either programmatically set up these
  • 00:36:49
    functions with your own function code in
  • 00:36:52
    Lambda functions um or you can actually
  • 00:36:55
    go through the console and click
  • 00:36:56
    together your own headboard using
  • 00:36:58
    functions and um thereby reduce the
  • 00:37:01
    development time and the time to results
  • 00:37:04
    um to just uh a day or so instead of
  • 00:37:07
    weeks of trying out and figuring out
  • 00:37:09
    stuff and and prompt engineering and
  • 00:37:11
    everything else lastly let's take a look
  • 00:37:14
    at a different problem what to do with
  • 00:37:17
    um malicious users who want to inject
  • 00:37:20
    something into the prompt to get it to
  • 00:37:22
    do something that you don't want to uh
  • 00:37:25
    what if you have some bad user behavior
  • 00:37:27
    that you want to mitigate against the
  • 00:37:29
    good news is that anthropic clot is
  • 00:37:31
    already very resistant to jailbreaks and
  • 00:37:33
    other bad behavior uh which is one
  • 00:37:35
    reason why at Amazon we like to partner
  • 00:37:38
    very much with entropic uh because they
  • 00:37:41
    focus a lot on responsible use of AI but
  • 00:37:44
    again you can also get one step further
  • 00:37:47
    by adding an harmlessness screen to
  • 00:37:50
    evaluate the appropriateness of the
  • 00:37:52
    input prompt or the results right think
  • 00:37:54
    of this like a firewall that you're
  • 00:37:56
    putting in front of the llm that checks
  • 00:37:59
    whether input or output are really um
  • 00:38:02
    compliant to your own company rules and
  • 00:38:06
    um if a armful prompt is detected you
  • 00:38:08
    can filter it out based on uh that
  • 00:38:11
    example surprise you can use a different
  • 00:38:13
    llm or another llm to do that screen for
  • 00:38:16
    you so here's how a prompt might look
  • 00:38:18
    like for an harmless L screen uh a human
  • 00:38:21
    user would like you to continue a piece
  • 00:38:23
    of content here is the content so far if
  • 00:38:25
    the content refers to harmful graphic or
  • 00:38:28
    illegal activities reply with why so
  • 00:38:30
    you're essentially using an llm as a
  • 00:38:32
    classifier to classify whether this is a
  • 00:38:34
    malicious prompt or not and then you can
  • 00:38:37
    use that to filter it out again you can
  • 00:38:39
    do it on your own or you can use a
  • 00:38:40
    feature from Amazon Bedrock called guard
  • 00:38:43
    raids for Amazon badrock that let you
  • 00:38:45
    set up those guard rails either from
  • 00:38:47
    predefined Rules or from your own rules
  • 00:38:49
    that you bring into your
  • 00:38:53
    application so we hope this was useful
  • 00:38:55
