Synopsis

A library for interacting with various generative AI LLMs

Description

A library for performing completions and chats with various generative AI LLMs (Large Language Models). Works today with Ollama and OpenAI with more to come in the future.

This project is very much in-progress and incomplete.

Using this library

An example, more available in src/example

import Control.Exception (Handler (..), catches)
import Data.Text.Lazy.IO qualified as TL
import GenAILib (ClientError, Request (..), jsonToText, mkRequest, numopt,
  stringopt, systemmsg, usermsg)
import GenAILib.HTTP (GenAIException, openaiV1Chat, openaiV1ChatJ,
  tokenFromFile)
import GenAILib.OpenAI (OpenAIRequest, getMessage)
main :: IO ()
main = do
  openaiJSON
  openaiData
-- A simple example with no error handling that expects an Aeson Value
-- (OpenAIRequest is an instance of ToJSON) and displays the encoded JSON
-- response
openaiJSON :: IO ()
openaiJSON = do
  let req :: OpenAIRequest = mkRequest "gpt-3.5-turbo" $ usermsg "Why is the sky blue?"
  token <- tokenFromFile "path/to/openai/key"
  TL.putStrLn . jsonToText =<< openaiV1ChatJ token Nothing req
-- Another example with exception handling that expects an OpenAIResponse
-- data structure, displaying that and also just the response text
openaiData :: IO ()
openaiData = do
  let req :: OpenAIRequest = mkRequest "gpt-3.5-turbo"
          (  systemmsg "Answer in the style of Bugs Bunny. Try to work the phrase \"What's up Doc?\" in somewhere."
          <> usermsg "Why is the sky blue?"
          <> numopt "temperature" 0.8
          <> stringopt "service_tier" "default"
          )
  token <- tokenFromFile "path/to/openai/key"
  res <- openaiV1Chat token Nothing req `catches`
    [ Handler (\(e :: GenAIException) -> error . show $ e)
    , Handler (\(e :: ClientError) -> error . show $ e)
    ]
  print res  -- The entire OpenAIResponse
  TL.putStrLn . getMessage $ res  -- Just the response Message Content
