Vertex’s implemented Gemini language, tuned endpoint, embedding, Gemini TTS speech, Cloud Speech-to-Text transcription, Veo video, and Interactions surface was audited against upstream Google Vertex 5.0.76. The current pass exposes the published embedding limits: 250 inputs for standard models and one input for Gemini multimodal embeddings. Imagen image generation/editing factories remain locally available for source compatibility after their removal from the current upstream package. Shared Gemini request behavior includes local JSON Schema $ref expansion with boolean-schema references, the Gemini 3.7 Flash low thinking floor, forward-compatible future-model capabilities, and response IDs; standard Vertex function-call and function-response IDs are omitted while server-tool IDs remain intact. Video supports first/last frame images, reference images, and top-level generateAudio precedence. Speech routes chirp* model IDs to authenticated Cloud TTS text:synthesize with Chirp voice/language defaults, LINEAR16/WAV handling, speed mapping, warnings, and metadata; other IDs keep Gemini TTS generateContent with WAV-wrapped PCM by default, raw PCM opt-in, multi-speaker provider options, sample-rate metadata, and upstream warnings. Google Batch, Gemini 3.5 transcription, and the broader shared Google language/safety/usage/request changes remain deferred to a dedicated Vertex pass. Node google-auth-library options, workflow serialization, ProviderV4 type names, and ESM-only packaging remain JS-runtime/package-surface concerns. The 5.0.76 pass adds an exact Maverick/Scout MaaS default of max_tokens: 8192 without overwriting caller values and inherits the audited Google, Anthropic, and OpenAI-compatible shared behavior.
