Know a free tier that's missing? [Open a PR](contributing.md). 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](https://ai.google.dev/gemini-api/docs/available-regions)).
[^2]: Groq rate limits vary by model. Llama 4 Maverick is limited to 500 RPD. Most other models get 14,400 RPD ([rate limits](https://console.groq.com/docs/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](https://openrouter.ai/docs/guides/routing/routers/free-models-router) (`openrouter/free`) and [model fallbacks](https://openrouter.ai/docs/guides/routing/model-fallbacks) for chaining models in priority order. Free providers may log prompts for training.
[^5]: Kilo Code free model list may change over time. nvidia/nemotron-3-super-120b-a12b:free is for trial use only — prompts are logged by NVIDIA. Auto-router `kilo-auto/free` routes to minimax/minimax-m2.5:free (80%) and stepfun/step-3.5-flash:free (20%).
[^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](https://modelscope.cn/docs/model-service/API-Inference/limits), [intro](https://modelscope.cn/docs/model-service/API-Inference/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 — click "Get your free token" on the OVHcloud AI Endpoints site. 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]: Free quota is signup-only with 90-day expiration and only granted in the Singapore / International region. Alibaba Cloud account requires phone/email verification but no credit card. After exhaustion, pay-as-you-go applies. Use the international endpoint `dashscope-intl.aliyuncs.com`; the China region (`dashscope.aliyuncs.com`) requires real-name verification.
[^9]: DeepSeek grants 5M free tokens at signup with a 30-day expiration. After expiry, pay-as-you-go applies. No credit card required at signup; prompts may be used to improve models unless explicitly opted out in account settings.
[^10]: Nebius grants $1 in free credits at signup, usable without a payment method. Credit card required to top up after exhaustion. Promo codes have expiration dates; the base $1 credit typically does not expire.
[^11]: Nscale grants $5 in free signup credits with no credit card required. Credits typically expire within 30–90 days (check console). Credit card required to top up. Pay-per-token after free credits exhausted. EU-sovereign, with data centers in Norway.
[^12]: xAI's $25 sign-up credit is one-time. Users who opt into the data-sharing program (prompts logged) receive an additional $150/month in credits, but the program requires $5 of prior spend before activation, so it is not a pure free tier. Several older Grok models (grok-4, grok-4-fast, grok-4-1-fast) were retired on May 15, 2026 and now redirect to grok-4.3 ([models](https://docs.x.ai/developers/models)).
