About Belvedir

Belvedir makes it cheap and easy for anyone to make custom AI models. We autonomously collect your data via trace SDK / app MCP / CUA agents and autonomously train custom models + harnesses + routers, privately deploy them, and recursively improve them as they are used. Our customers have seen 10x reductions in inference costs and 2x increases on benchmark scores. Custom AI models are going to win. Belvedir is the infrastructure needed to make trillions of them.
