Gemini Function Calling

Gemini function calling patterns documented by Google AI. Confirm endpoints, authentication, quotas, and regional availability on the official documentation page.

• Capabilities and endpoints as published in official developer documentation
• Authentication and client options as listed by the provider

• Feature availability, pricing, and rate limits change—verify on official docs
• Enterprise vs consumer surfaces may differ

Google AI documents function calling for Gemini so applications can declare functions the model may call, then execute those functions and return results—Google’s primary integration pattern for connecting Gemini to app logic and APIs.

• Declare function declarations in the request
• Model may return functionCall parts
• App executes functions and continues the conversation with function responses

• Supported models and modes are listed in Gemini docs and can change
• Parallel / constrained decoding options vary by surface

Gemini Function Calling is tracked so engineering and procurement teams can compare official developer surfaces, authentication posture, and documentation without relying on marketing copy.
