Free AI API access with an OpenAI-compatible endpoint.
Build AI chat, coding assistants, agent workflows, and prototypes with a free Yolo-Auto API key.
One API key

Simple routes
Chat completions, model listing, and usage metadata are exposed under /v1.
Predictable path
Start free, upgrade to unlimited when the project needs heavier traffic.
Quick setup
Create an account, copy your yolo_... API key, set your base URL to https://yolo-auto.com/v1, and use a public model from the models page.

Free AI API for real projects
Yolo-Auto is aimed at developers who want to wire AI into tools instead of clicking around a closed chatbot. Use it from JavaScript, Python, curl, or agent configs.
Compatible with common AI tooling
If a tool supports an OpenAI base URL, it can usually talk to Yolo-Auto with minimal changes.
From prototype to flat-rate production
The free tier helps you prove the integration. The unlimited plan gives heavy users a predictable monthly cost instead of per-token pricing.
Who Free AI API is actually for
Free AI API is best for developers and power users who want model access inside tools, agents, scripts, and apps — not just a closed consumer chatbot tab.
- Free API testing before you choose a paid LLM backend.
- Desktop chat through Yolo-Auto Desktop or another compatible client.
- Developer workflows that need an API key more than a closed chatbot UI.
The useful version of free AI is programmable
Generic free AI websites are fine for one-off prompts. Yolo-Auto is more useful when you want a key, an endpoint, model IDs, examples, and a path from testing to heavier usage.
That makes these pages more than a list of buzzwords: they point to the same developer workflow behind the product.
Try Free AI API with a normal chat completion
The fastest test is a single request against the OpenAI-compatible endpoint. Use your real Yolo-Auto API key, then swap the model ID if the models page shows a newer default.

You need OpenAI-compatible LLM access, predictable cost, free testing, and no prompt or response storage.
You need image generation, every model under the sun, a managed IDE, or a consumer-only chatbot with no API workflow.
