The world of generative AI is rapidly evolving, with constant updates and new model releases. Vertex AI provides access to over 150 models from Google, partners, and the open community. Gemini 1.5 Flash offers low latency and competitive pricing, while Gemini 1.5 Pro boasts an industry-leading 2-million-token context window for complex use cases. Imagen 3 excels in image generation with enhanced features and safety measures. Gemma 2 represents Google's next-generation open model with increased power and efficiency. Anthropic's Claude 3.5 Sonnet joins the Vertex AI model collection. Vertex AI's Model Builder enables model customization and all-in-one development from prototype to production. Context caching significantly reduces input costs for long-context applications. Controlled generation ensures desired output formats. Batch API optimizes efficiency for large numbers of non-latency-sensitive prompts. Enhanced model monitoring capabilities support models hosted outside of Vertex AI and provide unified management. Ray on Vertex AI simplifies distributed AI workloads. Prompt Management offers a library of prompts, versioning, and AI-generated suggestions. Evaluation Services assist in model performance assessment with Rapid Evaluation and specialized metrics for summarization and question answering.
