Details
GPT-AI is an API gateway that brings together more than 25 free AI chat endpoints, including OpenRouter, Pollinations, and PublicAI. You can make free calls to GPT-3.5 Turbo, GPT-4o-mini, Llama Instant, and roleplay models such as Dopple and Chat with Fiction.
You can call the Vercel demo deployed by the publisher directly, or deploy the project to your own Vercel in one go and use it. Send a POST request (a request that sends data) with userMessage to receive a response.
No signup, verification, or API key setup is required, and there is no separate expiration deadline. It cannot be used if the connected external artificial intelligence service is discontinued, and there are reportedly no call limits in theory while the external service is operating normally. The project is released as GPL-3.0 open source.
