Private AI model training infrastructure that continuously improves custom model weights from production traces using RL techniques.
Belvedir is an infrastructure platform that captures production agent traces and company data, curates them into training datasets and environments, and repeatedly fine-tunes custom model weights and memory layers using reinforcement learning—all within the customer's own VPC or dedicated single-tenant hardware. Customers own all weights and data, which never train other models. The platform sits alongside existing AI stacks, allowing gradual migration as custom models outperform incumbent frontier APIs on customer-defined benchmarks. Belvedir is currently in closed alpha. Belvedir is a product of Belvedir.
