What is it?

Awesome Free LLM APIs is a curated directory of large language model API providers that keep a free tier for text inference. For each provider it lists the base URL, the API key page, and a table of available models with context length, maximum output, modality and rate limits.

The providers are split into two groups: companies that train their own models, such as Google Gemini, Mistral, Cohere and Z AI, and third-party inference platforms that host open-weight models, such as Groq, Cloudflare Workers AI, Hugging Face, OpenRouter and NVIDIA NIM. Most endpoints are OpenAI SDK-compatible, and the entries note any exceptions, free-tier limits that change, and data-usage or identity-verification conditions.

The list is maintained in a README, with a glossary of RPM, RPD, TPM and TPD terms and a contributing guide for adding providers.

Key features

  • 01Lists free-tier endpoints with base URLs and direct links to API key pages.
  • 02Shows context length, max output, modality and rate limits for each model.
  • 03Covers both model vendors and third-party inference platforms.
  • 04Notes data-usage terms, regional restrictions and identity-verification requirements.
  • 05Most endpoints are OpenAI SDK-compatible.

Use cases

  • Prototyping an LLM feature without paying for API access.
  • Comparing context windows and rate limits across free providers before choosing one.
  • Finding a free fallback model for side projects or learning.

Quick start

  1. 1

    Get a free API key from the provider's key page (e.g. Groq console)

  2. 2

    Point an OpenAI SDK-compatible client at the provider's base URL, e.g. Groq

    https://api.groq.com/openai/v1

Things to know

  • Free tiers have strict rate limits and daily quotas that vary by provider.
  • Some providers may use free-tier prompts to improve their products or train models.
  • Cohere's free Trial key is limited to non-commercial use.
  • Some providers require real-name verification or account binding, such as ModelScope.
