awesome-free-llm-apis

awesome-free-llm-apis is a curated list of LLM APIs with ongoing free tiers, not one-off trial credits: Gemini, Groq, Mistral, OpenRouter, Cloudflare Workers AI, NVIDIA NIM and ten more. Each entry gives the base URL, free models, context sizes, rate limits and a link to the API key page. It's CC0.

Nothing to install. It's a README maintained by Manifest, an LLM routing company that plugs its own product up top. The footnotes beat most lists: who may train on free-tier prompts, who demands real-name ID checks, which models are being retired. Our spot check of Groq, OpenRouter and Cloudflare limits matched their own docs.

Solo builders and students: start here for a free prototype. Small teams: use it to pick a fallback, then pay. Larger teams: OpenRouter's free models stop at 50 requests a day until you buy $10 in credits, which tells you what these tiers are for.

The catch: "permanent" is the list's word, not the providers'. Google and Mistral no longer publish numeric free limits, and some rows were never live-tested. And on October 10 someone pushed a credential-stealing workflow to this repo; it was removed the next day. Check key links before pasting a key.
