Eingabe
If enabled, the model will use web search to enhance the generation with real-time information.
If set to true, the function will wait for the result to be generated and uploaded before returning the response. It allows you to get the result directly in the response. This property is only available through the API. Due to variability in Google’s underlying compute resources, inference times can fluctuate significantly. As a result, synchronous requests may hit timeouts.
If enabled, the output will be encoded into a BASE64 string instead of a URL. This property is only available through the API.
