Ships your product. Stac becomes the AI infrastructure behind it.

Claude and OpenAI charge by usage (tokens), which makes your bill unpredictable as your product grows. With Stac, you pay a fixed amount every month, you know exactly what you'll spend, and you're never cut off mid-work for hitting a limit.

There are no token charges and no volume limits. Each plan comes with simultaneous capacity sized for its usage, so your product keeps responding, with no blocking and no extra charges. There's only a safety rate limit against abuse, well above what a product in normal operation consumes.

No. Each plan already comes with the model best suited for it, so you don't have to worry about that choice. Choosing your own model is only available on the Enterprise plan, with custom configuration.

Higher plans include more advanced models, more simultaneous usage capacity, and extra features like custom training on Max and dedicated infrastructure on Enterprise.

Yes. If you want to fully isolate different products or use cases, you can subscribe to more than one Stac plan at the same time. Each subscription is independent, with its own keys and knowledge base. If what you need is a more capable model, the way to go is upgrading your plan.

No. You get an API key ready to integrate into your product, with no need to set up a server, GPU, or infrastructure.
