Free LLM APIs

Methodology

What's included

LLM API providers that let you call models without paying: free tiers with rate limits, individual free models (like OpenRouter's :free variants) and free monthly credit or quotas (66 models and offers from 13 providers). One-off sign-up credits that expire, chat apps without an API, and models you have to host yourself are left out. Services that stopped their free offer are listed under "Gone or not free anymore" on the home page.
