Baar Breakdown

About Baar

I left an agent loop running overnight. Woke up to a $47 bill — 20,000 GPT-4o tokens answering "what time is it?" queries. Baar-Core would have stopped it at $0.10. Before the first overage call. No network request made. $0 spent.

Who Is Baar For?

Baar is designed for a range of users, including:

• Teams deploying autonomous agents in production
