Playground side panel on model pages — Model detail pages now include a “Playground” button in the header that opens a slide-out panel for testing the model inline, with support for all available modalities.
OpenCode integration guide — Added a guide for configuring OpenCode with OpenRouter to the coding agents documentation.
Fixed: BYOK model filter showing incomplete results — Bring-your-own-key provider pages now show all models a provider serves, not just models whose cheapest endpoint is from that provider.
Fixed: 500 errors for router model variant mismatches — Requests to router models with unavailable variants (e.g. openrouter/auto:thinking) now return a descriptive 404 instead of a generic 500 error.
Fixed: vertical scrollbar on models page modality tabs — Removed an unwanted vertical scrollbar on the models page modality filter tabs.
