What is FreeLLMAPI?

A free LLM API, without the free-tier grind — one OpenAI-compatible key that routes across every provider with a genuine free tier.

FreeLLMAPI is a free LLM API: an open-source, self-hosted router that puts every provider with a real free tier behind a single OpenAI-compatible endpoint — Google AI Studio, Groq, Cerebras, NVIDIA, Mistral, OpenRouter, Cohere, Cloudflare Workers AI, Z.ai, Ollama, HuggingFace and more. Point any OpenAI SDK at it and it picks a model that still has quota, fails over when one is rate-limited, and tracks usage so you stay under every cap. No credit card, no per-provider signups to juggle.

You get 235+ model families across 28 providers — Kimi, Qwen3, DeepSeek, Gemini Flash, Llama, GLM, Nemotron, GPT-OSS and the rest — behind one endpoint, with roughly 4 billion free tokens a month in aggregate. The router is open source and self-hosted; Premium keeps the model catalog live so new free models and quota changes reach you the day they ship.

How it works

  1. Install the router — it runs locally and keeps your provider keys on your machine.
  2. Add free provider keys on the Keys page — no credit card needed.
  3. Call one OpenAI-compatible endpoint; FreeLLMAPI routes across every free tier and fails over automatically.
Use every one of these through one key. FreeLLMAPI is an open-source, self-hosted router that puts all these free tiers behind a single OpenAI-compatible endpoint and fails over when one is rate-limited. Browse the catalog or go live.
