OpenAI

When using OpenAi models, llm-exe will make POST requests to https://api.openai.com/v1/chat/completions. All models are supported if you pass openai.chat.v1 as the first argument, and then specify a model in the options.

Basic Usage

OpenAi Chat

const llm = useLlm("openai.chat.v1", {
  model: "gpt-4o", // specify a model
});

OpenAi Chat By Model

const llm = useLlm("openai.gpt-4o", {
  // other options,
  // no model needed, using gpt-4o
});

INFO

You can use the following models using this shorthand:

• openai.gpt-4o
• openai.gpt-4o-mini

Authentication

To authenticate, you need to provide an OpenAi API Key. You can provide the API key various ways, depending on your use case.

1. Pass in as execute options using openAIApiKey
2. Pass in as setup options using openAIApiKey
3. Use a default key by setting an environment variable of OPENAI_API_KEY

Generally you pass the LLM instance off to an LLM Executor and call that. However, it is possible to interact with the LLM object directly, if you wanted.

// call the LLM directly with a prompt
await llm.call(prompt);
