gpt4free (g4f) is a large-scale, community-driven Python library that aggregates dozens of free AI providers (LLMs, image, audio, video) into a unified, OpenAI-compatible interface. It provides multiple access modes: a Python client library (sync/async), a FastAPI-based API server, a Flask web GUI, a CLI tool, a Model Context Protocol (MCP) server for tool calling, a browser extension, a Discord bot, an Android app, and a Go launcher. The architecture is provider-based: each AI service (e.g., ChatGPT, Gemini, DeepSeek, Copilot, Grok, Perplexity) is wrapped in an adapter class implementing a common `AsyncGeneratorProvider` interface. The system handles authentication via cookies, OAuth flows, HAR files, and browser automation (CDP/nodriver), and supports streaming, tool/function calling, image generation, audio synthesis, and web search. It is primarily an application for consuming free AI models, not a research or data pipeline project, though it includes some data-oriented utilities like token optimization and usage tracking.
