Per-token pricing punishes exploration

Developers should not have to stop an agent every few minutes to check spend. Flat-rate access makes prototypes, coding tools, and long conversations easier to run.

Simple upgrade path

Start free for integration testing, then upgrade when your agent, chat client, or app needs more room.

Built around efficient model hosting

Yolo-Auto focuses on efficient open-weight routes and lean infrastructure so pricing can stay simple.

Use cases

Who Flat-Rate AI API is actually for

Flat-Rate 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.

Developers who want one monthly AI cost center.
Teams comparing fixed subscription pricing against usage-based APIs.
Agent builders who need room to test prompts, tools, and failure modes.

Positioning

Flat-rate pricing is operationally simpler

Usage-based APIs are fine when every request is predictable. They get annoying when you are experimenting, debugging, or letting an agent work through a problem. A flat-rate AI API turns that variable cost into a planning number.

Yolo-Auto keeps the same developer ergonomics while changing the pricing model: OpenAI-compatible requests, one API key, and a monthly plan for heavier usage.

Implementation

Try Flat-Rate 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.
