Awesome Free LLM APIs is a curated list of language model APIs that offer permanent free tiers for text inference.
The project addresses the challenge of finding reliable, no-cost access to LLM APIs by cataloging providers that maintain permanent free offerings. It organizes these services into two main categories: Provider APIs, which are run by the companies that train or fine-tune the models themselves, and Inference providers. Each entry documents the base URL, available models, context windows, maximum output tokens, modality support, and rate limits. The README notes that all endpoints are OpenAI SDK-compatible unless otherwise specified, and each link directs users to the provider's API key page.
Developers should use this list when building projects that require free LLM access without credit card requirements or when exploring multiple model options before committing to paid tiers. It suits prototyping, learning, and production applications with modest throughput needs. The list includes providers like Aion Labs, Cohere, and Google Gemini, each with different specializations—Aion Labs focuses on roleplay and storytelling, while others offer general-purpose or multimodal capabilities. The project also mentions that all these free LLM APIs are available through manifest.build for building reliable agents.
The repository maintains an organized, structured format with detailed specifications for each provider, making it straightforward to compare offerings. Updates appear to focus on keeping provider information current and adding newly available free-tier options to the list.
