How this page is kept

Every limit is read from the provider's own documentation, pricing or help pages on the date shown, and links to them. When a provider shows a number only inside its logged-in console, or does not state it, we say so and leave it unpublished; nothing is filled in from forums or other trackers. API credits that come with a paid subscription (ChatGPT Pro, Claude Max, Hugging Face PRO) are paid plans, not free tiers, and are left out.

Closed: GitHub Models (30 Jul 2026). The playground, catalogue and inference API closed; GitHub points users to Azure AI Foundry or GitHub Copilot. Source

Once you pay, the cost calculator prices a month of your usage on every ranked model, and coding plans compares flat-rate subscriptions.

Free LLM APIs: questions people ask

Which LLM APIs have a free tier?
Google Gemini API, Mistral AI, Groq, Cohere, Cloudflare Workers AI, SambaNova Cloud and NVIDIA NIM API catalog offer ongoing free use within limits. OpenRouter has free models; Anthropic API, Cerebras Inference and Fireworks AI give a one-off credit. Checked on 2 Nov 2026.
Is there a free LLM API for production use?
Not really: free tiers are rate-limited for testing. Cohere's trial keys and NVIDIA's API catalog rule out production or commercial use outright, and Google requires the paid tier for apps offered in the EEA, Switzerland and the UK. Plan on a paid tier for anything users depend on.
Do free tiers use my prompts for training?
Some do. Google Gemini API: Free-tier prompts and responses are used to improve Google products and may be read by human reviewers, except in the EEA, Switzerland and the UK. Mistral AI: Free-mode input and output may be used to train Mistral's models unless you opt out in the admin panel. OpenRouter: Depends on the provider serving the model; account settings control whether free models may be routed to providers that train on prompts. Read each provider's terms before sending anything private.
Which free API has the best models?
Google's free tier includes current Gemini Flash models, and OpenRouter has free variants of some models. Compare what each scores on the BenchLeader Index before you build on it; the free model is rarely the provider's best one.
How often do free tiers change?
Often, and usually without notice. Every row here was read from the provider's own page on 2 Nov 2026; where a provider shows a number only inside its console, the row says it is not published rather than guess.
