Guardrails: “Select all” and collapsible member lists — The member and API key pickers in the guardrails editor now support “Select all / Deselect all” with one click, and long lists of selected items collapse behind a “+N” toggle. Docs
Cursor IDE endpoint — Added a Cursor-compatible /api/v1/cursor endpoint, enabling Cursor IDE users to connect to OpenRouter directly.
“Others” bucket in router activity charts — The token usage breakdown chart on router pages now aggregates models beyond the top 5 into an “Others” category, so every bar segment in the chart is accounted for in the legend.
Fixed: Anthropic prompt caching broken when using server tools — Requests with cache_control and server tools (such as datetime or web_search) now correctly forward the caching directive, restoring prompt caching for Anthropic models in the Responses API.
