Belvedir

Custom model factory: it records an agent's calls with an SDK, connects apps over MCP, cleans the data into task datasets, fine-tunes an open model, scores it on the customer's own evals next to the base and a frontier model, and serves it on an OpenAI-compatible endpoint or exports the weights.

• Belvedir Platform Sold on its own

  Platform that turns an agent's own traffic into a custom model: install the package to record every call, bring in app data over MCP, cluster raw sessions into task datasets, fine-tune an open model, score it on the customer's evals against the base model and a frontier model, and serve it on Belvedir's inference or download the weights. Free during a closed alpha; no prices are published.
