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.
Sets the name of the generative model. This is required for building a GenerativeModel
instance. Supported format: "gemini-pro", "models/gemini-pro",
"publishers/google/models/gemini-pro", where "gemini-pro" is the model name. Valid model
names can be found in the Gemini models documentation:
https://cloud.google.com/vertex-ai/docs/generative-ai/learn/models#gemini-models
Sets com.google.cloud.vertexai.VertexAI that contains the default configs for the
generative model. This is required for building a GenerativeModel instance.
