This demo exhibits the flagship new function: passing BOTH a built-in software
(Google Search) and a customized perform declaration in a single API name.
Gemini will:
Flip 1 → Search the net for real-time information, then request our customized
perform to get climate knowledge.
Flip 2 → We provide the perform response; Gemini synthesizes every little thing.
Key factors:
• google_search and function_declarations go within the SAME Device object
• include_server_side_tool_invocations have to be True (on ToolConfig)
• Return ALL components (incl. thought_signatures) in subsequent turns
