  • Connect your AlloyDB Omni instance to agents that support the Model Context Protocol (MCP), which help you with development workflows. For more information, see Use AlloyDB Omni with MCP, Gemini CLI, and other agents.

  • Build LLM-powered applications using LlamaIndex. For more information, see Build LLM-powered applications using LlamaIndex.

  • Generate vector embeddings using an LLM hosted by Vertex AI that translates a text string into an embedding, which is the model's representation of the given text's semantic meaning as a numeric vector. For more information, see Generate embeddings.

  • Set up, configure, and generate SQL statements using AlloyDB AI natural language, which lets you create user-facing generative AI applications using natural language to query databases. For more information, see Generate SQL queries from natural language.
