Awesome Free LLM APIs
A curated list of LLM API providers offering permanent free tiers for text inference, with base URLs, supported models, context limits and rate limits for each.
This is a curated list of LLM APIs that offer permanent free tiers for text inference, split into provider APIs run by the companies that train or fine-tune the models themselves and separate inference providers. All endpoints are OpenAI SDK-compatible unless otherwise noted, and each entry links to the provider's API key page.
Listed providers include Aion Labs, Cohere and Google Gemini, among others, with tables giving each model's context window, maximum output, supported modality and rate limits, such as requests per minute or tokens per day, along with notes on free-tier terms such as whether prompts may be used to improve the provider's own products.
