For more information, see [Gemini Code Assist supported features](/gemini/docs/codeassist/overview#supported-features).\n\nCode customization, a feature in\n\n[Gemini Code Assist](/gemini/docs/codeassist/overview) Enterprise,\nlets you get code suggestions from Gemini Code Assist\nEnterprise that are based on your organization's private repositories, and thus\naligned to your organization's coding style.\n\nWith code customization, developers can use remote context from your\norganization directly in the IDE, as the following diagram shows:\n\nAs you code, Gemini Code Assist searches your private index for\ncode that is similar to what you're trying to write. It then includes relevant\nmatches in the code prompt and sends these matches to the\nGemini Code Assist recommendations service. Code customization\nkeeps recommendations fresh by reindexing your codebase every 24 hours to\nensure that code suggestions remain up to date.\nGemini Code Assist returns the generated code to you.\n\nUnlike the full codebase awareness feature, which is limited to searching files\nin the current folder and open tabs in your IDE, code customization searches all\nrepositories in your index. After code customization is set up, it works as part\nof the code completion and code generation features.\n\nBoth Gemini Code Assist and code customization are managed\nservices. You license usage by seats per month.\n\nSecuring access and storage of private code\n-------------------------------------------\n\nGoogle provides security of your stored private code in several ways:\n\n- We index and store your code in a dedicated single-tenant environment.\n- [Administrative access controls](https://cloud.google.com/assured-workloads/cloud-provider-access-management/docs/administrative-access) help prevent Google employees from accessing your content without justification and, optionally, explicit approval.\n- The Gemini model doesn't train on your private source code.\n- Your results are private to you, and we don't share your results with other customers.\n\nFor further details on Google's security measures, see the\n[Google security overview](https://cloud.google.com/security/overview/whitepaper).\n\nHere's how you can control access to your data:\n\n- You can use Identity and Access Management (IAM) permissions to help control individuals who can get code suggestions from your codebase.\n- You can [create an `.aiexclude` file](/gemini/docs/codeassist/code-customization#optional_choose_which_files_are_not_indexed) to choose specific repositories or parts of repositories that Gemini Code Assist indexes.\n\nTo configure code customization in your IDE, see\n\n[Configure Gemini Code Assist code customization](/gemini/docs/codeassist/code-customization).\n\n\nLimitations\n-----------\n\n- Google limits the number of code repository indexes to one for each project and for each organization.\n- The maximum number of repositories that can be indexed is 20,000.\n- The maximum number of repository groups per code repository index is 500.\n- The maximum number of repositories per repository group is 500.\n- Code customization is supported in the VS Code Gemini Code Assist extension (version 2.18.0+), the IntelliJ Gemini Code Assist plugin (version 1.1.0), Cloud Workstations, and the Cloud Shell Editor.\n- Code customization supports repositories hosted on github.com, gitlab.com, bitbucket.org, and on-premises repositories hosted on GitLab Enterprise, GitHub Enterprise, and Bitbucket Data Center.\n- Code customization doesn't support [GitHub Enterprise Cloud IP restrictions](https://docs.github.com/en/enterprise-cloud@latest/organizations/keeping-your-organization-secure/managing-security-settings-for-your-organization/managing-allowed-ip-addresses-for-your-organization).\n- Code customization supports only Developer Connect connections in the following locations (regions):\n - `us-central1`\n - `europe-west1`\n - `asia-southeast1`\n- Code customization doesn't index media. Code customization supports only\n documentation (in Markdown) and the following languages:\n\n - C, C++, and C#\n - Golang\n - Java\n - JavaScript\n - Kotlin\n - PHP\n - Python\n - Rust\n - TypeScript\n\n All other coding languages are not indexed or used in code customization. To\n request support for a coding language, click **Send feedback** on this page,\n and then select **Product feedback**.\n\nWhat's next\n-----------\n\n1.
