Product changes

  • Personal profile pages — Profiles have a brand new design with a refreshed activity-chart layout.
  • Deep Linking to Workspaces — Workspace URLs now resolve via an immutable workspace id, so links keep working after a slug rename. Docs.
  • Redesigned model page header — The header section on every model page has been rebuilt to be faster to scan and easier to navigate between providers and tabs.
  • Tier-aware pricing pills on provider cards — Provider cards on the model page now surface flex and priority pricing as compact pills so you can see how each service tier changes cost at a glance. Docs.
  • Redesigned BYOK provider detail page — The Bring-Your-Own-Key provider detail page has been refreshed with a cleaner provider summary and clearer connection status. Docs.
  • Docs button on app pages — App pages on /apps now include a Docs button that links directly to relevant cookbook guides and integration docs for that framework.
  • Logs table renders entities as pills — The logs table now displays model, provider, app, and other entity columns as compact pills, and the Supporting Models column is consolidated into a count with a click-through popup instead of an overflowing list.
  • Guardrails search and status filter — The guardrails list now supports searching by name and filtering by status. Docs.
  • Session-id-based provider stickiness — Requests that share the same session id now route to the same provider when possible, improving cache hit rates for multi-turn agentic workflows. Docs.
  • Hermes Agent cookbook — Added a Hermes Agent cookbook page covering how to use Nous Research’s Hermes Agent with OpenRouter.
  • Human-in-the-loop tools announcement — Published a blog post announcing human-in-the-loop tool calling support across the API and SDKs.
  • Fixed: Jupyter notebook attachments in chat — Attaching .ipynb files in the chatroom no longer balloons the prompt with embedded cell outputs.
  • Fixed: server-tool cost aggregation — The cost_details field returned to clients now aggregates costs correctly when a server tool runs multiple inner turns inside one user-facing request.
