Starting April 29, 2025, Gemini 1.5 Pro and Gemini 1.5 Flash models are not available in projects that have no prior usage of these models, including new projects. For details, see Model versions and lifecycle.
Optional. One or more function declarations to be passed to the model along
with the current user query. Model may decide to call a subset of these
functions by populating FunctionCall in the
response. User should provide a
FunctionResponse for each function call
in the next turn. Based on the function responses, Model will generate the
final response back to the user. Maximum 64 function declarations can be
provided.
