Google Gemini and Vertex provider.

Classes

Type	Summary
FileStreamPart	A streamed file part. The shared stream model has no file delta, so this carries the bytes.
GoogleAssistantPart	An assistant content part.

GoogleEmbeddingModel	Gemini embedding model. One value uses :embedContent; several values use :batchEmbedContents.
GoogleFileAssistantPart	An assistant file or reasoning file.

GoogleFileUserPart	A user file. Kind is url, data, text, or reference.
GoogleFinishReason	Maps Gemini finish reasons onto the shared finish-reason enum.
GoogleGeneratedFile	A generated file, including thought images.
GoogleImageModel	Gemini image generation. The call runs through GoogleLanguageModel with the IMAGE response modality, so the google provider options apply, and googleSearch enables Google Search grounding.
