This repository curates over 240 free Large Language Model (LLM) APIs from more than 28 providers, simplifying the discovery, comparison, and configuration of accessible AI models. It targets developers and researchers seeking cost-effective LLM access, offering a structured, machine-readable directory with daily updates and direct API key links.

How It Works

The project maintains a comprehensive, machine-readable directory of free LLM APIs, updated daily via automated monitoring. It details rate limits, context windows, and credit card requirements for each provider. This data powers freellm.net, a companion website for comparing models, generating one-click configuration snippets for tools, and accessing API keys.

Quick Start & Requirements

Users can quickly integrate free LLM APIs by selecting a provider (e.g., Groq, which requires no credit card), obtaining an API key, and using provided code examples for Python (OpenAI SDK) or bash. For one-click configurations for tools like Claude Code or Cursor, freellm.net/config/ is the resource. No specific installation for the repository itself is required; it serves as a directory.

Highlighted Details

• Lists 240+ free LLM APIs from 28+ providers (e.g., Google Gemini, NVIDIA NIM, Groq).
• Features daily data refreshes via automated monitoring for up-to-date information.
• Includes credit card transparency, indicating providers that require payment details.
• Offers one-click configuration snippets for popular tools via freellm.net/config/.
• Provides a side-by-side model comparison tool on freellm.net.

Maintenance & Community

The project is actively maintained with daily data updates. Contributions for new models, data fixes, or config snippets are welcomed via issues or PRs. The project is licensed under MIT.

Licensing & Compatibility

Licensed under the permissive MIT License, allowing commercial use, modification, and distribution with minimal restrictions.

Limitations & Caveats

The directory focuses exclusively on free tiers, which may have lower performance or stricter rate limits than paid services. Some providers listed under "Renewable Credits" might require an initial top-up or credit card. The "Local / Self-Hosted" section is presented as an alternative, not an integrated part of the API directory.
