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.

[^1]: Free tier not available in the EU, UK, or Switzerland (available regions).
[^2]: Groq rate limits were reduced in 2026. Most models now get 1,000 RPD on the free tier (down from 14,400). Llama 4 Maverick has been deprecated. See 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 the Ollama API.
[^4]: Free models default to 50 RPD per model. 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. Free providers may log prompts for training.
[^5]: Kilo Code free model list changes frequently. nvidia/nemotron-3-super-120b-a12b:free is for trial use only — prompts are logged by NVIDIA. Auto-router kilo-auto/free dynamically picks from the current free pool.
[^6]: API-Inference is free for registered users. Current published limits are 2,000 requests/day per user (total across models), with per-model daily quotas dynamically adjusted and capped at 500; concurrency is also dynamically rate-limited. Requires Alibaba Cloud account binding and real-name verification (limits, intro).
[^7]: OVHcloud AI Endpoints offers a permanent free anonymous tier (2 requests per minute per IP, per model) with no signup or API key required. Higher rate limits (400 RPM per Public Cloud project per model) require an API key and are billed pay-as-you-go per token; new Public Cloud accounts get up to $200 in free trial credits. Models are hosted in EU data centers.
[^8]: SambaNova grants $5 in initial credits (valid 30 days) on top of the permanent free tier. The free tier itself persists indefinitely with 20 RPM, 20 RPD, and 200K TPD per model. No credit card required. OpenAI SDK-compatible.
