LLM::Functions

In brief

This Raku package provides functions and function objects to access, interact, and utilize Large Language Models (LLMs), like OpenAI, [OAI1], PaLM, [ZG1], and MistralAI, [MAI1].

For more details how the concrete LLMs are accessed see the packages "WWW::OpenAI", [AAp2], "WWW::PaLM", [AAp3], "WWW::MistralAI", [AAp9], and "WWW::Gemini", [AAp11].

The LLM functions built by this package can have evaluators that use "sub-parsers" -- see "Text::SubParsers", [AAp4].

The primary motivation to have handy, configurable functions for utilizing LLMs came from my work on the packages "ML::FindTextualAnswer", [AAp6], and "ML::NLPTemplateEngine", [AAp7].

A very similar system of functionalities is developed by Wolfram Research Inc.; see the paclet "LLMFunctions", [WRIp1].

For well curated and instructive examples of LLM prompts see the Wolfram Prompt Repository. Many of those prompts (≈220) are available in Raku and Python -- see "LLM::Prompts", [AAp8], and "LLMPrompts", [AAp10], respectively.

The article "Generating documents via templates and LLMs", [AA1], shows an alternative way of streamlining LLMs usage. (Via Markdown, Org-mode, or Pod6 templates.)

Installation

Package installations from both sources use zef installer (which should be bundled with the "standard" Rakudo installation file.)

To install the package from Zef ecosystem use the shell command:

zef install LLM::Functions

To install the package from the GitHub repository use the shell command:

zef install https://github.com/antononcube/Raku-LLM-Functions.git

Design

"Out of the box" "LLM::Functions" uses "WWW::OpenAI", [AAp2], "WWW::PaLM", [AAp3], and "WWW::MistralAI", [AAp9]. Other LLM access packages can be utilized via appropriate LLM configurations.

Configurations:

Are instances of the class LLM::Functions::Configuration
Are used by instances of the class LLM::Functions::Evaluator
Can be converted to Hash objects (i.e. have a .Hash method)

New LLM functions are constructed with the function llm-function.

The function llm-function:

Has the option "llm-evaluator" that takes evaluators, configurations, or string shorthands as values
Returns anonymous functions (that access LLMs via evaluators/configurations.)
Gives result functions that can be applied to different types of arguments depending on the first argument
Can take a (sub-)parser argument for post-processing of LLM results
Takes as a first argument a prompt that can be a:
- String
- Function with positional arguments
- Function with named arguments

Here is a sequence diagram that follows the steps of a typical creation procedure of LLM configuration- and evaluator objects, and the corresponding LLM-function that utilizes them:

sequenceDiagram
  participant User
  participant llmfunc as llm-function
  participant llmconf as llm-configuration
  participant LLMConf as LLM configuration
  participant LLMEval as LLM evaluator
  participant AnonFunc as Anonymous function
  User ->> llmfunc: ・prompt<br>・conf spec
  llmfunc ->> llmconf: conf spec
  llmconf ->> LLMConf: conf spec

  LLMEval ->> llmfunc: evaluator object
  llmfunc ->> AnonFunc:  create with:<br>・evaluator object<br>・prompt
  AnonFunc ->> llmfunc: handle
  llmfunc ->> User: handle

Here is a sequence diagram for making a LLM configuration with a global (engineered) prompt, and using that configuration to generate a chat message response:

sequenceDiagram
  participant WWWOpenAI as WWW::OpenAI
  participant User
  participant llmfunc as llm-function
  participant llmconf as llm-configuration
  participant LLMConf as LLM configuration
  participant LLMChatEval as LLM chat evaluator
  participant AnonFunc as Anonymous function
  User ->> llmconf: engineered prompt
  llmconf ->> User: configuration object
  User ->> llmfunc: ・prompt<br>・configuration object
  llmfunc ->> LLMChatEval: configuration object
  LLMChatEval ->> llmfunc: evaluator object

  AnonFunc ->> WWWOpenAI: ・engineered prompt<br>・message
  WWWOpenAI ->> User: LLM response

Configurations

OpenAI-based

Here is the default, OpenAI-based configuration:

use LLM::Functions;
.raku.say for llm-configuration('OpenAI').Hash;

# :evaluator(Whatever)
# :module("WWW::OpenAI")
# :function(proto sub OpenAITextCompletion ($prompt is copy, :$model is copy = Whatever, :$suffix is copy = Whatever, :$max-tokens is copy = Whatever, :$temperature is copy = Whatever, Numeric :$top-p = 1, Int :$n where { ... } = 1, Bool :$stream = Bool::False, Bool :$echo = Bool::False, :$stop = Whatever, Numeric :$presence-penalty = 0, Numeric :$frequency-penalty = 0, :$best-of is copy = Whatever, :api-key(:$auth-key) is copy = Whatever, Int :$timeout where { ... } = 10, :$format is copy = Whatever, Str :$method = "tiny", Str :$base-url = "https://api.openai.com/v1") {*})
# :max-tokens(300)
# :temperature(0.8)
# :prompts($[])
# :name("openai")
# :images($[])
# :tools($[])
# :api-key(Whatever)
# :api-user-id("user:109176182730")
# :base-url("https://api.openai.com/v1")
# :tool-prompt("")
# :tool-response-insertion-function(WhateverCode)
# :argument-renames(${:api-key("auth-key"), :stop-tokens("stop")})
# :stop-tokens($[])
# :examples($[])
# :format("values")
# :tool-request-parser(WhateverCode)
# :total-probability-cutoff(0.03)
# :model("gpt-3.5-turbo-instruct")
# :prompt-delimiter(" ")

Here is the ChatGPT-based configuration:

.say for llm-configuration('ChatGPT').Hash;

# tool-request-parser => (WhateverCode)
# total-probability-cutoff => 0.03
# model => gpt-3.5-turbo
# api-user-id => user:475496933842
# images => []
# argument-renames => {api-key => auth-key, stop-tokens => stop}
# max-tokens => 300
# module => WWW::OpenAI
# tool-prompt => 
# format => values
# stop-tokens => []
# examples => []
# temperature => 0.8
# prompts => []
# tool-response-insertion-function => (WhateverCode)
# tools => []
# function => &OpenAIChatCompletion
# prompt-delimiter =>  
# api-key => (Whatever)
# base-url => https://api.openai.com/v1
# name => chatgpt
# evaluator => (my \LLM::Functions::EvaluatorChat_6288007030840 = LLM::Functions::EvaluatorChat.new(context => "", examples => Whatever, user-role => "user", assistant-role => "assistant", system-role => "system", conf => LLM::Functions::Configuration.new(name => "chatgpt", api-key => Whatever, api-user-id => "user:475496933842", module => "WWW::OpenAI", base-url => "https://api.openai.com/v1", model => "gpt-3.5-turbo", function => proto sub OpenAIChatCompletion ($prompt is copy, :$role is copy = Whatever, :$model is copy = Whatever, :$temperature is copy = Whatever, :$max-tokens is copy = Whatever, Numeric :$top-p = 1, Int :$n where { ... } = 1, Bool :$stream = Bool::False, :$stop = Whatever, Numeric :$presence-penalty = 0, Numeric :$frequency-penalty = 0, :@images is copy = Empty, :api-key(:$auth-key) is copy = Whatever, Int :$timeout where { ... } = 10, :$format is copy = Whatever, Str :$method = "tiny", Str :$base-url = "https://api.openai.com/v1") {*}, temperature => 0.8, total-probability-cutoff => 0.03, max-tokens => 300, format => "values", prompts => [], prompt-delimiter => " ", examples => [], stop-tokens => [], tools => [], tool-prompt => "", tool-request-parser => WhateverCode, tool-response-insertion-function => WhateverCode, images => [], argument-renames => {:api-key("auth-key"), :stop-tokens("stop")}, evaluator => LLM::Functions::EvaluatorChat_6288007030840), formatron => "Str"))

Remark: llm-configuration(Whatever) is equivalent to llm-configuration('OpenAI').

Remark: Both the "OpenAI" and "ChatGPT" configuration use functions of the package "WWW::OpenAI", [AAp2]. The "OpenAI" configuration is for text-completions; the "ChatGPT" configuration is for chat-completions.

PaLM-based

Here is the default PaLM configuration:

.say for llm-configuration('PaLM').Hash;

# tool-request-parser => (WhateverCode)
# stop-tokens => []
# images => []
# format => values
# name => palm
# api-user-id => user:948311569993
# argument-renames => {api-key => auth-key, max-tokens => max-output-tokens, stop-tokens => stop-sequences}
# examples => []
# api-key => (Whatever)
# prompt-delimiter =>  
# model => text-bison-001
# prompts => []
# temperature => 0.4
# function => &PaLMGenerateText
# tool-response-insertion-function => (WhateverCode)
# tool-prompt => 
# tools => []
# evaluator => (Whatever)
# module => WWW::PaLM
# max-tokens => 300
# total-probability-cutoff => 0
# base-url =>

Basic usage of LLM functions

Textual prompts

Here we make a LLM function with a simple (short, textual) prompt:

my &func = llm-function('Show a recipe for:');

# -> $text, *%args { #`(Block|6288098091184) ... }

Here we evaluate over a message:

say &func('greek salad');

# Ingredients:
# - 1 large cucumber, diced
# - 1 bell pepper, diced
# - 1 red onion, thinly sliced
# - 2-3 tomatoes, diced
# - 1 cup Kalamata olives, pitted
# - 1 cup feta cheese, crumbled
# - 1/4 cup extra virgin olive oil
# - 2 tablespoons red wine vinegar
# - 1 teaspoon dried oregano
# - Salt and pepper to taste
# 
# Instructions:
# 1. In a large salad bowl, combine the cucumber, bell pepper, red onion, tomatoes, and olives.
# 2. In a small bowl, whisk together the olive oil, red wine vinegar, oregano, salt, and pepper.
# 3. Pour the dressing over the vegetables and toss to combine.
# 4. Add the feta cheese on top of the salad.
# 5. Serve immediately or refrigerate for 1-2 hours to allow the flavors to meld together before serving. Enjoy your delicious Greek salad!

Positional arguments

Here we make a LLM function with a function-prompt and numeric interpreter of the result:

my &func2 = llm-function(
        {"How many $^a can fit inside one $^b?"},
        form => Numeric,
        llm-evaluator => 'palm');

# -> **@args, *%args { #`(Block|6288154113224) ... }

Here were we apply the function:

my $res2 = &func2("tennis balls", "toyota corolla 2010");

# 48

Here we show that we got a number:

$res2 ~~ Numeric

# False

Named arguments

Here the first argument is a template with two named arguments:

my &func3 = llm-function(-> :$dish, :$cuisine {"Give a recipe for $dish in the $cuisine cuisine."}, llm-evaluator => 'palm');

# -> **@args, *%args { #`(Block|6288120035248) ... }

Here is an invocation:

&func3(dish => 'salad', cuisine => 'Russian', max-tokens => 300);

# **Ingredients:**
# 
# * 1 head of cabbage (chopped)
# * 2 carrots (grated)
# * 1 cucumber (chopped)
# * 1/2 red onion (chopped)
# * 1/2 cup of mayonnaise
# * 1/4 cup of sour cream
# * Salt and pepper to taste
# 
# **Instructions:**
# 
# 1. In a large bowl, combine the cabbage, carrots, cucumber, and onion.
# 2. In a small bowl, whisk together the mayonnaise, sour cream, salt, and pepper.
# 3. Pour the dressing over the salad and toss to coat.
# 4. Serve immediately or chill for later.
# 
# **Tips:**
# 
# * For a more flavorful salad, add some chopped fresh herbs, such as dill or parsley.
# * You can also add some protein to the salad, such as shredded chicken or crumbled bacon.
# * If you don't have any sour cream on hand, you can use yogurt or even just milk to thin out the mayonnaise.
# * This salad is best served cold, so make sure to chill it for at least a few hours before serving.

LLM example functions

The function llm-example-function can be given a training set of examples in order to generating results according to the "laws" implied by that training set.

Here a LLM is asked to produce a generalization:

llm-example-function([ 'finger' => 'hand', 'hand' => 'arm' ])('foot')

# leg

Here is an array of training pairs is used:

'Oppenheimer' ==> (["Einstein" => "14 March 1879", "Pauli" => "April 25, 1900"] ==> llm-example-function)()

# April 22, 1904

Here is defined a LLM function for translating WL associations into Python dictionaries:

my &fea = llm-example-function( '<| A->3, 4->K1 |>' => '{ A:3, 4:K1 }');
&fea('<| 23->3, G->33, T -> R5|>');

# { 23:3, G:33, T:R5 }

The function llm-example-function takes as a first argument:

Single Pair object of two scalars
Single Pair object of two Positional objects with the same length
A Hash
A Positional object of pairs

Remark: The function llm-example-function is implemented with llm-function and suitable prompt.

Here is an example of using hints:

my &fec = llm-example-function(
        ["crocodile" => "grasshopper", "fox" => "cardinal"],
        hint => 'animal colors');

say &fec('raccoon');

# panda

Using predefined prompts

Using predefined prompts of the package "LLM::Prompts", [AAp8], can be very convenient in certain (many) cases.

Here is an example using "Fixed That For You" synthesis:

use LLM::Prompts;

llm-synthesize([llm-prompt('FTFY'), 'Wha is ther population?'])

# What is the population?

Using chat-global prompts

The configuration objects can be given prompts that influence the LLM responses "globally" throughout the whole chat. (See the second sequence diagram above.)

For detailed examples see the documents:

Chat objects

Here we create chat object that uses OpenAI's ChatGPT:

my $prompt = 'You are a gem expert and you give concise answers.';
my $chat = llm-chat(chat-id => 'gem-expert-talk', conf => 'ChatGPT', :$prompt);

# LLM::Functions::Chat(chat-id = gem-expert-talk, llm-evaluator.conf.name = chatgpt, messages.elems = 0)

$chat.eval('What is the most transparent gem?');

# Diamond is the most transparent gem.

$chat.eval('Ok. What are the second and third most transparent gems?');

# The second most transparent gem is sapphire, and the third most transparent gem is emerald.

Here are the prompt(s) and all messages of the chat object:

$chat.say

# Chat: gem-expert-talk
# ⸺⸺⸺⸺⸺⸺⸺⸺⸺⸺⸺⸺⸺⸺⸺⸺⸺⸺⸺⸺⸺⸺⸺⸺⸺⸺⸺⸺⸺⸺⸺⸺⸺⸺⸺⸺⸺⸺⸺⸺⸺⸺⸺⸺⸺⸺⸺⸺⸺⸺⸺⸺⸺⸺⸺⸺⸺⸺⸺⸺

AI-vision functions

Consider this image:

Here we import the image (as a Base64 string):

use Image::Markup::Utilities;
my $url = 'https://raw.githubusercontent.com/antononcube/MathematicaForPrediction/master/MarkdownDocuments/Diagrams/AI-vision-via-WL/0iyello2xfyfo.png';
my $img = image-import($url);
$img.substr(^100)

# ![](data:image/jpeg;base64,iVBORw0KGgoAAAANSUhEUgAAArwAAAK8CAIAAACC2PsUAAAA1XpUWHRSYXcgcHJvZmlsZSB0e

Here we apply OpenAI's AI vision model gpt-4-vision-preview (which is the default one) over the URL of the image:

llm-vision-synthesize('Describe the image.', $url);

# The image is an infographic titled "Cyber Week Spending Set to Hit New Highs in 2023". It shows estimated online spending on Thanksgiving weekend in the United States for the years 2019 through 2023, with 2023 being a forecast. The data is presented in a bar chart format, with different colored bars representing each year.
# 
# There are three categories on the horizontal axis: Thanksgiving Day, Black Friday, and Cyber Monday. The vertical axis represents spending in billions of dollars, ranging from $0B to $12B.
# 
# The bars show an increasing trend in spending over the years for each of the three days. For Thanksgiving Day, the spending appears to have increased from just over $4B in 2019 to a forecast of around $6B in 2023. Black Friday shows a rise from approximately $7B in 2019 to a forecast of nearly $10B in 2023. Cyber Monday exhibits the highest spending, with an increase from around $9B in 2019 to a forecast of over $11B in 2023.
# 
# There is an icon of a computer monitor with a shopping tag, indicating the focus on online spending. At the bottom of the image, the source of the data is credited to Adobe Analytics, and the logo of Statista is present, indicating that they have produced or distributed the infographic. There are also two icons, one resembling a Creative Commons license and the other a share or export button.

Here we apply Gemini's AI vision model gemini-pro-vision over the image:

llm-vision-synthesize('Describe the image.', $img, e => 'Gemini');

# The image shows the estimated online spending on Thanksgiving weekend in the United States from 2019 to 2023. The y-axis shows the spending amount in billions of dollars, while the x-axis shows the year. The data is presented in four bars, each representing a different year. The colors of the bars are blue, orange, green, and yellow, respectively. The values for each year are shown below:
# 
# * 2019: $7.4 billion
# * 2020: $9.0 billion
# * 2021: $10.7 billion
# * 2022: $11.3 billion
# * 2023: $12.2 billion (estimated)
# 
# The image shows that online spending on Thanksgiving weekend has increased steadily over the years. In 2023, online spending is expected to reach $12.2 billion, up from $7.4 billion in 2019.

Remark: Currently, Gemini works with (Base64) images only (and does not with URLs.) OpenAI's vision works with both URLs and images.

The function llm-vision-function uses the same evaluators (configurations, models) as llm-vision-synthesize.

Potential problems

With PaLM with certain wrong configuration we get the error:

error => {code => 400, message => Messages must alternate between authors., status => INVALID_ARGUMENT}
