Bug Fixes
- Fixed Gemma 4 models failing with include_server_side_tool_invocations error when combining built-in tools with function calling. Gemma 4 does not support file search (RAG), and the Interactions API does not yet support the required tool_config parameter for combining google_search with function calling.
- RAG options are now disabled in the UI when Gemma 4 is selected
- Switching to Gemma 4 automatically clears any active RAG selection
- google_search and function calling are no longer sent together for Gemma 4
