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.
Perform an online explanation.
If
deployed_model_id
is specified, the corresponding DeployModel must have
explanation_spec
populated. If
deployed_model_id
is not specified, all DeployedModels must have
explanation_spec
populated.
