Provides a curated index of 80+ free AI services organized by capability (chat, image, video, voice, APIs) with detailed usage limits and model availability, distinguishing between no-signup and signup-required options. The project aggregates access to diverse model providers—from frontier models (GPT-4o, Claude, DeepSeek) to open-source alternatives (Llama, Mistral, Qwen)—alongside developer APIs like Ollama and g4f that enable local or self-hosted deployment. Includes performance leaderboards (HuggingFace, Chatbot Arena, OpenRouter) to help developers compare models across instruction-following, multilingual NLP, and user-feedback metrics.
