Private AI models are going to win. Belvedir is the infrastructure needed to make trillions of them. Belvedir makes it cheap and easy for anyone to make private AI. Just connect us to your agent traces through our SDK and we can autonomously train custom models + harnesses + routers, privately host them, and recursively improve them as they are used. Our customers have seen up to 10x reductions in inference costs and 2x increases on benchmark scores.
