Belvedir on the record

What they shipped

  • From its YC profile: 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. Connect us to your agent traces through our SDK and we autonomously train custom models + harnesses + routers, privately deploy 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. (source)
  • Its own site describes it as: "Control your AI, business, knowledge, and IP with Belvedir. See everything your AI does in production and improve it on your terms." (source)
