Product changes

  • May Release Spotlight blog post -- Published the May Release Spotlight covering speech and transcription APIs, Model Fusion, private models, enterprise workspace controls, and new model launches.
  • Fixed: model-specific default parameters not shown on API tab -- The Parameters table on model detail pages now displays the model's actual default overrides (e.g. top_p: 0.95) instead of generic global defaults. Docs
  • /llms.txt and /llms-full.txt now resolve at the domain root -- openrouter.ai/llms.txt and openrouter.ai/llms-full.txt now redirect to their generated equivalents under /docs/, following the llms.txt specification.
  • Fixed: verbosity parameter default in docs -- The verbosityparameter reference no longer lists medium as the default; the effective default varies by upstream provider.
