 ### ✨ New Features
 
+- **Models.dev Integration:** Integrated models.dev as the authoritative runtime source for model pricing, capabilities, and specifications, overriding hardcoded prices. Includes a settings UI to manage sync intervals, translation strings for all 30 languages, and robust test coverage.
+- **Provider Native Capabilities:** Added support for declaring and checking native API features (e.g. `systemInstructions_supported`) preventing failures by sanitizing invalid roles. Currently configured for Gemini Base and Antigravity OAuth providers.
 - **API Provider Advanced Settings:** Added per-connection custom `User-Agent` overrides for API-key provider connections. The override is stored in `providerSpecificData.customUserAgent` and now applies to validation probes and upstream execution requests.
