What is FreeTheAI

FreeTheAI is a free, OpenAI-compatible AI API. One account and one API key give you access to dozens of free models, including GLM 5.3, Kimi K3, MiniMax M3, Gemini 3.5 Flash, and gpt-oss, with 50 free requests a day and no credit card.

Because it speaks the same protocols as OpenAI and Anthropic, anything that lets you change the base URL can use it: the official OpenAI and Anthropic SDKs, roleplay apps like JanitorAI and SillyTavern, chat apps like Open WebUI and LibreChat, and coding agents like Claude Code, Codex, Cline, and Aider.

What you get

• One key for every free model. Model IDs start with fta/, for example fta/zai/glm-5.3 and fta/kimi/k3. The Models page lists every model with its context size and the endpoints it supports.
• Three wire formats. Chat Completions, Responses, and Anthropic Messages. Every free model answers on all three, streaming and tool calls included, so you can keep the SDK you already use.
• Web search for any model. /v1/search returns current results with text excerpts, and /v1/answer returns a short answer with its sources.
• Privacy. FreeTheAI does not store your prompts or replies.

How the free tier works

1. You create a free account on freetheai.org with a Gmail, Outlook, Yahoo, or iCloud address and confirm the email.
2. You create an API key. It starts with ftai_ and is shown once.
3. Once a day you do a short check-in on freetheai.org. It unlocks free models until 00:00 UTC.
4. You send requests from any app or SDK.

Every account starts with 50 free requests a day, resetting at 00:00 UTC, and gets 50 more a day for linking Discord. Free accounts run one request at a time. Requests that fail, or that are turned away because a model is busy, do not count. The details are on Limits and the daily reset.

Paid models and plans are coming soon. Nobody needs to pay to use the free tier.

The addresses you need

What	Value
Base URL (OpenAI SDKs and most apps)	https://api.freetheai.org/v1
Full chat URL (apps that want the whole address, such as JanitorAI)	https://api.freetheai.org/v1/chat/completions
Anthropic base URL (Claude Code and the Anthropic SDK)	https://api.freetheai.org
Auth header	Authorization: Bearer ftai_...
OpenAPI 3.1 spec	api.freetheai.org/openapi.json

FreeTheAI used to live at freetheai.xyz. It moved to freetheai.org and api.freetheai.org; old freetheai.xyz links redirect, but old api.freetheai.xyz addresses and old model IDs no longer work.

Next steps

• Quickstart: your first request in curl, Python, JavaScript, or TypeScript.
• App guides: step-by-step setup for 24 apps.
• API reference: every endpoint, parameter, and response.
• Errors: every error message, word for word, with the fix.
