## What it is
A TypeScript replication of gpt4free that provides free access to GPT-4 and other LLM models by reverse-engineering various websites offering ChatGPT-like services. It exposes an OpenAI-compatible API so applications can use these models without paid API keys.

## Use cases
- access gpt-4 without paying for an openai api key
- run a free openai-compatible api server
- reverse-engineer chatgpt websites for free llm access
- use gpt-3.5 and claude models for free in my app
- self-host a free chatgpt api proxy
- experiment with multiple llm models without accounts

## When to choose
- you want free, unofficial access to GPT-3.5/GPT-4 style models via an OpenAI-compatible endpoint
- you're experimenting or prototyping and can tolerate unstable, frequently-breaking upstream sites
- you want a Node.js/TypeScript base to add new reverse-engineered providers

## When to avoid
- you need reliable, production-grade LLM access with guarantees - the underlying sites go offline often
- you need a legally sanctioned API; this violates most providers' terms of service
- you need the latest models or official features like function calling and fine-tuning

## Facets
- artifact type: library
- maturity: maintenance
- function: llm-inference, http-server, reverse-engineering, chatbot
- domain: large-language-models, artificial-intelligence, chatbots, developer-tools
- platform: cross-platform
- tags: gpt4free, free-api, openai-compatible, reverse-proxy, chatgpt, gpt-4, api-wrapper, nodejs, typescript
