Guardrails enforcement drill-down — Rows in the Guardrails enforcement chart now link directly to the matching generations on the Logs page.
Entity hover cards — Models, providers, and apps across the dashboard now show hover cards with a preview and a link to the entity’s page.
Responses API tool call handling — Conversation history containing tool calls with missing optional fields (e.g. no arguments or id) no longer causes 400 errors from providers. The router now defaults missing arguments to "{}" and generates a stable id when absent.
File upload OCR handling — Files processed with OCR no longer fail when routed to text-only models. Previously, OCR-extracted images could be sent to models that don’t support vision input, causing errors.
