GPT4Free
Unified free access to LLMs and media models
GPT4Free aggregates multiple free LLM and media providers, offering a Python/JS client, web GUI, and OpenAI‑compatible API for easy integration and local deployment via Docker or pip.
Overview
Overview
GPT4Free is a community‑driven toolkit that brings together a variety of free large‑language‑model and media‑generation services under a single, consistent interface. It abstracts provider‑specific quirks, letting developers call text, image, audio, or video generation endpoints just like they would an official OpenAI API.
Capabilities
The project ships with synchronous and asynchronous Python clients, a browser‑based JavaScript SDK, and a FastAPI‑powered "Interference API" that mimics OpenAI’s REST contract. A local web GUI provides an instant chat experience, while optional provider‑login containers help capture authentication cookies for services that require them.
Deployment
Users can run GPT4Free in a full Docker container, a slim multi‑arch image for x86_64/arm64, install the Python package via pip, or download a native Windows executable. Minimal prerequisites include Python 3.10+ and Chrome/Chromium for providers that rely on browser automation. Comprehensive documentation and community channels support quick setup and customization.
Highlights
Multi‑provider adapters for text, image, audio, and video generation
OpenAI‑compatible FastAPI endpoint (Interference API)
Cross‑platform clients: Python library, async support, and browser JavaScript SDK
Docker images (full and slim) plus native Windows executable for simple deployment
Pros
- Free access to many LLMs without API keys
- Flexible deployment options (Docker, pip, Windows exe)
- Unified API abstracts provider differences
- Active community with documentation and support channels
Considerations
- Reliance on third‑party provider availability may cause outages
- Some providers need Chrome/Chromium installed
- Performance varies across providers and may be slower than official APIs
- Legal/compliance considerations when using unofficial endpoints

Fit guide
Great for
- Developers prototyping AI features without incurring API costs
- Researchers testing multiple models side‑by‑side
- Hobbyists wanting a local chat UI for free models
- Teams needing an OpenAI‑compatible endpoint for existing code
Not ideal when
- Production systems requiring guaranteed SLA and official support
- Environments where installing Chrome/Chromium is prohibited
- Use cases demanding the latest proprietary model performance
- Compliance‑heavy industries needing audited data handling
How teams use it
Integrate free LLMs into a chatbot
Deploy the FastAPI endpoint and point existing OpenAI‑compatible code to it, enabling chat functionality without paying for API usage.
Generate images for content creation
Use the Python client’s image generation method with providers like Flux to produce royalty‑free visuals directly from scripts.
Run a local AI playground on a Raspberry Pi
Pull the slim Docker image on arm64, start the web GUI, and experiment with text and media models offline.
Automate provider login for cookie‑based services
Launch the optional desktop login inside the container to capture authentication cookies, then reuse them for subsequent API calls.

Frequently asked questions
Do I need an OpenAI API key?
No, GPT4Free routes requests through free public providers; an OpenAI key is not required.
Which operating systems are supported?
Linux, macOS, Windows (via .exe), and ARM64 devices via the slim Docker image.
How do I choose which provider to use?
The client selects a default provider, but you can specify a model name or provider in the request to target a specific backend.
Is Chrome required for all providers?
Only providers that rely on browser automation need Chrome/Chromium; other backends work without it.
Can I run GPT4Free behind a firewall?
Yes, the FastAPI server can be bound to any host/port, and Docker allows network configuration to fit restricted environments.
