chatgpt.js and jan

A JavaScript library for interacting with ChatGPT's API complements a local LLM runtime, as they serve different use cases—one requires cloud connectivity to OpenAI's service while the other provides offline inference—rather than competing for the same deployment scenario.

About jan

janhq/jan

Jan is an open source alternative to ChatGPT that runs 100% offline on your computer.

Supports both local LLM inference via HuggingFace and cloud model integration (OpenAI, Anthropic, Mistral, Groq), with an OpenAI-compatible API server on localhost:1337 for third-party app integration. Built on Tauri for cross-platform desktop deployment and Llama.cpp for efficient local model execution, plus Model Context Protocol support for agentic workflows.
