Gemini 3.6 Flash and 3.5 Flash-Lite are generally available (GA)

Gemini 3.6 Flash and Gemini 3.5 Flash-Lite are now generally available (GA) and available for production use. These models are designed to improve upon their predecessors' capabilities, including improved token usage and improved document understanding. See the linked model information pages for more information.

This release includes some potentially breaking changes from previous Flash and Flash-Lite models:

• Sampling parameters: Custom values for temperature, top-K, and top-P are not supported and will be ignored if set. • Penalty parameters: Custom values for frequency and presence penalty parameters are not supported. Setting these will result in an API error. • API turn structure: API requests where the last input turn has a role of Model are no longer supported and will return an error:

Interactions API: Requests where the last object in the input array has "type": "model_output" will fail. • GenerateContent API: Requests where the last object in the contents array has "role": "model" will fail.
