All but most trivial LLM applications require complex prompt handling, development, evaluation, secure use, and deployment techniques. Bosquet is building LLMOps functionality (see the tutorial bellow for the parts that are now implemented):
An example of a composable prompt definition to define a prompt answering question with role assumption.
(complete
;Prompt components
{:role "As a brilliant {{who-you-are}} answer the following question."
:QnA "{{role-completed}} {{question}} Answer: {% llm-generate var-name=answer %}"
:self-eval "{{QnA-completed}} Is this a correct answer? {% llm-generate var-name=test%}"}
;Data
{:who-you-are "astronomer"
:question "What is the distance from Moon to Io?"})
=>
{:role-completed
"As a brilliant astronomer answer the following question."
:QnA-completed
"As a brilliant astronomer answer the following question. What is the distance from Moon to Io?
Answer: The average distance between the Moon and Io is approximately 384,400 km (238,855 mi)."
:QnA-completion

"The average distance between the Moon and Io is approximately 384,400 km (238,855 mi)."}
:self-eval-completed
"As a brilliant astronomer answer the following question. What is the distance from Moon to Io?
Answer: The average distance between the Moon and Io is approximately 384,400 km (238,855 mi).
Is this a correct answer? Yes, that is a correct answer."
:self-eval-completion {:test "Yes, that is a correct answer."}}
- Support access to all main LLM models: GPT, Bloom, and Stable Diffusion to start with.
- Provide scaffolding for prompt building methods: Role Promoting, Chain of Thought, Zero-Shot CoT, Self Consistency, and more.
- Vulnerability assessment and monitoring. How possible are prompt leak or injection attacks? Can prompt generate harmful content?
- Prompt quality evaluation.
- Developed and tested prompt deployment to Cloudflare Workers, AWS Lambda, or self-host via REST API.
- Prompt service reliability guarantees.
Bosquet relies on Selmer and Pathom to implement composable prompts with advanced template definition functionality.
Composability allows focusing on prompt language and logic, not worrying about resolving the dependencies and sequence of the prompt execution.
In this prompt definition, Bosquet will ensure the following sequence of execution:
- First data needs to be filled in: title - "The Parade" and style - "horror"
- These are all the dependencies needed for synopsis generation, and at the place specified with
((bosquet.openai/complete))
an OpenAI API is called to get the results. - Once the synopsis is completed, the review can be done. The synopsis/completion dependency is automatically fulfilled and the review prompt
((bosquet.openai/complete))
will be called to produce the review - Generated text for review will go under review/completion key.
Bosquet uses Selmer to define its templates with all the functionality coming from Selmer's templating language:
- filters
- loops
- branches
- default values to name a few.

Bosquet provides the following core functionality:
- defines prompt templates
- resolves dependencies between prompts
- produces AI completions
The following section will show how to use it.
Let's say we want to generate a synopsis of the play. The synopsis
is to be generated from title
and genre
inputs.
Prompt template definition is done with Selmer templating library.
It uses {{DATA}}
syntax to specify where data needs to be injected.
Bosquet adds to Selmer a specification of where AI generation calls should
happen. This is indicated with the {% llm-generate %}
tag.
Generation is done with the following Bosquet features:
llm-generate
will receive all the text preceding it with already filled-in template slots. This text is used as the prompt to be sent to the completion API.bosquet.openai
namespace defines completion function, that calls OpenAI API to initiate the completion
(def synopsis-template
"You are a playwright. Given the play's title and t's genre
it is your job to write synopsis for that play.
Title: {{title}}
Genre: {{genre}}
Playwright: This is a synopsis for the above play:
{% llm-generate model=text-davinci-003 var-name=play %}")
Note the optional var-name
parameter. This is the name of the var to hold generation result and it can be used as a reference in other templates or the same template further down. If var-name
is not specified "llm-generate"
will be used as the name.
Bosquet will be invoking OpenAI API thus make sure that OPENAI_API_KEY
is present as the environment variable.
llm-generate
call to the OpenAI will use configuration parameters specfied
in that tag and reflect parameters specified by Open AI API.
The tag uses the same names. If config parameters are not used, then defaults
are used. Note that the default model is Ada, in production Davinci would be a
natural choice.
The impl
can be usd to switch betwen he original openai API or teh Azure openAI API.
They need different environemnt variables for authentication, see here
{impl openai or azure , openai default
model ada
temperature 0.6
max-tokens 80
presence-penalty 0.4
frequence-penalty 0.2
top-p 1
n 1}
The call to generation function takes in:
template
defined abovedata
is the data to fill in the template slots (title
andgenre
)
The generation comes back with a tuple where the first member will contain all the text which got its slots filled in and generated completion. The second member of the tuple will contain only the AI-completed part.
(def synopsis
(gen/complete-template
synopsis-template
{:title "Mr. X" :genre "crime"}))
With the play synopsis generated, we want to add a review of that play. The review prompt template will depend on synopsis generation. With Bosquet we do not need to worry about resolving the dependencies it will be done automatically (powered by Pathom).
(def review-template
"You are a play critic from the New York Times.
Given the synopsis of play, it is your job to write a review for that play.
Play Synopsis:
{{synopsis-completion.synopsis}}
Review from a New York Times play critic of the above play:
{% llm-generate model=text-davinci-003 %}")
Both templates need to be added to a map to be jointly processed by Bosquet.
(def play
{:synopsis synopsis-template
:review review-template})
The review prompt template contains a familiar call to generation function and
a reference - {{synopsis-completion.synopsis}}
- to a generated text for the synopsis.
The reference points to synopsis-completion.synopsis
where synopsis-completion
points to the map of all completions done by synopsis
template and .play
pics out the var-name
used for that specific generation
(multiple generations can be defined in one template).
Thus the references between prompts and completions are constructed using this pattern
[prompt-map-key]-completion.[var-name]
To process this more advanced case of templates in the dependency graph,
Bosquet provides the gen/complete
function taking:
prompts
map defined abovedata
to fill in fixed slots (Selmer templating)
(def review (gen/complete play {:title "Mr. X" :genre "crime"}))
Selmer provides lots of great templating functionality. An example of some of those features.
Let's say we want to get a batch sentiment processor for Tweets.
A template for that:
(def sentimental
"Estimate the sentiment of the following batch of {{text-type|default:text}} as positive, negative or neutral:
{% for t in tweets %}
* {{t}}
{% endfor %}
Sentiments:
{% llm-generate model=text-davinci-003 %}")
First, Selmer provides 'for' tag to process collections of data.
Then, {{text-type|default:text}}
shows how defaults can be used. In this case,
if text-type
is not specified "text"
will be used.
Tweets to be processed
(def tweets
["How did everyone feel about the Climate Change question last night? Exactly."
"Didn't catch the full #GOPdebate last night. Here are some of Scott's best lines in 90 seconds."
"The biggest disappointment of my life came a year ago."])
(def sentiments (gen/complete-template sentimental
{:text-type "tweets" :tweets tweets}))
