1If you see lower storage in your service, you can upgrade.

2High density (HD) mode is an option available within the standard S3 service that allows a larger number of indexes to be created in a single service. For information on supported limits, refer here.

3Resources backed by confidential compute are available at additional cost. Some features are limited or unavailable, including semantic ranker, agentic retrieval, skillset execution, and vectorization. Learn more about confidential computing here.

智能体检索

Agentic retrieval incorporates conversation history and a bring-your-own-model (BYOM) integration into query planning, using an agentic framework to run and manage the RAG query pipeline.

How billing works for agentic retrieval:

  • Agentic retrieval billing has two parts: query planning and query execution (ranking)
  • Query planning is billed through the model used (i.e. Azure OpenAI GPT series) with input and output tokens. This is separate from agentic retrieval Azure AI Search costs.
  • Query execution (ranking) is part of the agentic retrieval process and billed through Azure AI Search.

You will incur separate charges and licenses for knowledge connections that you bring on your own, including Microsoft SharePoint and Grounding with Bing Search (Available as web knowledge source for Azure AI Foundry IQ and Azure AI Search).

语义排名程序

Semantic ranker improves search relevance by finding content that is semantically similar to query terms. The service is only available for accounts on Basic, Standard tiers (S1, S2, and S3), and Storage-Optimized (L1 and L2) and has two pricing plans within those tiers. Use semantic ranker when you want to improve the quality of search results and optimize the user experience.

附加功能

Custom Entity Lookup skill detects and labels documents containing user-defined words and phrases, and is available for all Basic, Standard, and Storage-Optimized tiers. It is ideal for defining and detecting specific entities in your data.

Document Cracking: Image Extraction retrieves content from a file during the built-in indexer document cracking phase and/or within the enrichment pipeline. Text extraction is free, while image extraction is billed during the initial document cracking step and/or when invoking the Document Extraction skill. Use this functionality when you have documents that contain images.

有关如何为企业选择正确 SKU 的指南

每个企业在成长和发展过程中都有独特的需求。浏览以下指南,从而了解如何从适用于组织的商业模式开始。

  • 在选择 SKU 之前,须仔细考虑对搜索服务的要求。以下是要问的重要问题:

    • 应用程序用户可以编写哪些示例查询?
    • 他们将搜索哪种信息?
    • 用户要筛选或整理搜索结果吗?
    • 需要多少索引?
    • 原始数据文件或 blob 存储的大小是多少?
    • 未来需要空余空间来引入新的文档/数据吗?
  • Azure AI Search is offered in combinable search "units" that vary by storage and throughput. Selecting the optimal pricing tier for your solution is based on the following factors:

    • Storage requirements: This refers to the amount of data you need to store in your search service. Each tier has a storage limit per partition, and you can add up to 12 partitions on a search service. It's important that your service has enough space for your data and has headroom to grow if you plan on ingesting more data.

    Pro Tip: The storage size of your search index will typically be smaller than the size of your raw data, particularly for files like PDFs and images. The best way to assess the storage size required for your search index is to index a representative sample of documents into your search index in the Azure portal with the Import Data Wizard.


    • Queries per Second (QPS): The throughput of your search service, often measured in QPS, will depend on your data and the types of queries users will issue. It's best to run performance tests to understand the throughput a particular tier can handle for your scenario but we have performance benchmarks that show the throughput different customer scenarios. Check out our performance benchmarking guidance to see sample customer scenarios.

    For additional guidance, please see our documentation: Choosing a Pricing Tier.

  • Customers can further optimize their search experience with add-on services in the "Additional Features" table below. We also recommend customers read the following guidance on how to manage costs:

  • For additional help, please see our options for one-on-one guidance.

  • 对于 Microsoft Azure AI 搜索,我们基于在任何给定时间范围内使用的单位数量按统一的可预测每小时费率对你收费。
  • 已按一小时内检测到的最后一个搜索单位计数向你计费。如果从两个单位开始,然后扩展到四个单位,然后在整个一小时内纵向缩减回两个单位,则可能会向你收取两个单位的费用。
  • 停止按钮用于停止服务实例的流量。结果是,你的服务仍将运行,并且会继续按小时费率收费。
  • 将按单位存在的每小时的统一费率对你收费,无论使用量是多少,也无论单位存在时间是否不足一个小时。例如,如果你创建一个单位,然后在五分钟后删除它,那么你的帐单将反映一个单位小时的收费。
  • Azure AI 搜索单位组合提供额外吞吐量和存储。例如,要从 1,500 万份文档扩展到 3,000 万(额外分区),客户可以购买两个单位。要增加吞吐量(额外副本),他们可以购买两个单位。要同时增加存储和吞吐量,客户将需要购买四个单位(2 个副本 x 2 个分区 = 4 个搜索单位)。
  • 免费版是 Azure AI 搜索的免费版本,设计用于为开发者提供沙盒以测试 Azure AI 搜索的功能和实现。该版本不设计用于生产工作负载。“基本版”、“标准版”和“存储优化版”是生成从自主管理的搜索即服务解决方案中受益的应用程序的入门选项。标准版提供随着应用程序需要扩展的存储和可预测吞吐量。存储优化版本提供了明显更多的存储空间,且每 TB 的价格更低。对于极高需求应用,请联系 azuresearch_contact@microsoft.com
  • Azure AI Search is available in the new Microsoft Azure portal. First, you must sign up for an Azure subscription, then you can add an Azure AI Search account to your Azure subscription via the gallery in the preview portal. Get more information.
  • Agentic retrieval autonomously decides the best sources and methods for retrieving information, enhancing response quality through reasoning and planning. Semantic ranker improves search relevance by understanding and leveraging the semantics of user queries. Learn more here.
