Know a free tier that’s missing? Open a PR. Include the provider, endpoint, rate limits (link to their docs), and a few notable models. Trial credits and time-limited promos don’t count.

Footnotes

  • RPM – requests per minute. RPD – requests per day.
  • “Limits undocumented” means the provider doesn’t publish their rate limits.
  • All endpoints are OpenAI SDK-compatible unless noted.
  • Each link points to the provider’s API key page.

  1. Free tier not available in the EU, UK, or Switzerland (available regions). ↩︎

  2. 14,400 RPD only applies to Llama 3.1 8B Instant. Most other models (Llama 3.3 70B, Llama 4 Scout, Kimi K2, etc.) are limited to 1,000 RPD (rate limits). ↩︎

  3. Ollama Cloud measures usage by GPU time, not tokens or requests. Free tier described as “light usage” with session limits resetting every 5 hours and weekly limits every 7 days. Pro (50x more) and Max (250x more) plans available. Not OpenAI SDK-compatible; uses Ollama API ↩︎

  4. Free models default to 50 RPD. A one-time purchase of $10+ in credits unlocks 1,000 RPD for free models. OpenRouter also offers a Free Models Router (openrouter/free) and model fallbacks for chaining models in priority order. ↩︎
