Star snapshot：⭐ 145.6k · 2026-09 snapshot
Open GitHub repoWhy it's picked
MIT framework for agents and LLM apps: compose models, tools and retrieval. The usual starting point when you want that flow in code across many providers.
Laojin's advice
Follow the official Quickstart; don't copy 2023 APIs. LangGraph / LangSmith are related products, not this package. For a knowledge-Q&A prototype, Dify is often faster.
Stars are a 2026-07 snapshot for scale reference only; see GitHub for live numbers.

AllModelsAPIOne key for many models
AllModelsAPI is a multi-model API gateway: one key reaches many models through an OpenAI-compatible interface — point your existing code at a new base URL and you're migrated. It's not a demo: our own production workloads run on it every day.
