AlloyDB AI 是 AlloyDB Omni 中包含的一套功能,可让您构建企业生成式 AI 应用。如需详细了解 AlloyDB 的 AI/机器学习功能,请参阅构建生成式 AI 应用。
借助具有 AlloyDB AI 的 AlloyDB Omni,您可以查询远程机器学习模型,以使用从机器学习模型生成的在线预测和文本嵌入。具有 AlloyDB AI 的 AlloyDB Omni 还可以处理来自其他内容(例如图片)的向量嵌入,例如,如果您使用 google_ml.predict_row 接口并自行在查询中进行转换。
根据您要在其中安装具有 AlloyDB AI 的 AlloyDB Omni 的位置,选择以下选项之一:

For more information about the\nAI/ML functionality of AlloyDB, see\n[Build generative AI applications](/alloydb/omni/15.12.0/docs/ai/overview-ai).\n\nAlloyDB Omni with AlloyDB AI lets you query remote ML models to work with online predictions and text embeddings generated from ML models. AlloyDB Omni with AlloyDB AI can also process vector embeddings from other content such as an image, for example, if you use the `google_ml.predict_row` interface and do the translation yourself in the query.\n\nBased on where you want to install AlloyDB Omni with AlloyDB AI, select one of the following options: \nSingle-server Kubernetes GDC air-gapped\n\nVerify AlloyDB Omni with AlloyDB AI installation\n------------------------------------------------\n\nTo verify your installation is successful and uses model prediction, enter the following: \n\n CREATE EXTENSION IF NOT EXISTS google_ml_integration CASCADE;\n\n SELECT array_dims(embedding('text-embedding-005', 'AlloyDB AI')::real[]);\n\nThe output looks similar to the following: \n\n array_dims\n ------------\n [1:768]\n (1 row) \n\n| **Note:** Vertex AI model support is governed by Vertex AI model versioning and lifecycle guidelines. For more information about stable versions, see [Model versions and lifecycle](/vertex-ai/generative-ai/docs/learn/model-versions).\n\nIn the previous query, the `embedding()` call generates embeddings for the input text `AlloyDB AI`.\n`array_dims` returns the dimensions of the array returned by `embedding()`.\nSince the `text-embedding-005` model returns an output with 768 dimensions, the output is `[768]`.\n\nWhat's next\n-----------\n\n- [Run and connect to AlloyDB Omni](/alloydb/omni/15.12.0/docs/run-connect)\n- [Manage AlloyDB Omni](/alloydb/omni/15.12.0/docs/manage)\n- [Build generative AI applications using AlloyDB AI](/alloydb/omni/15.12.0/docs/ai/overview-ai)\n- [Register and call remote AI models](/alloydb/omni/15.12.0/docs/ai/register-model-endpoint)"]]
