llm-exe

A package that provides simplified base components to make building and maintaining LLM-powered applications easier.

• Write functions powered by LLM's with easy to use building blocks.
• Pure Javascript and Typescript. Allows you to pass and infer types.
• Support for text-based and chat-based prompts (gpt-3.5-turbo and gpt-4).
• Supercharge your prompts by using handlebars within prompt template.
• Allow LLM's to call functions (or call other LLM executors).
• Not very opinionated. You have control on how you use it.
