# Enabling AI CodeFix
Sonar’s AI CodeFix uses a large language model (LLM) to automatically generate AI-driven code fixes for the issues discovered by SonarQube Server. The feature is available in SonarQube Server, Enterprise and Data Center editions.
Using AI CodeFix is simple. When you request a fix, the affected code and issue description are sent to an LLM. AI CodeFix then proposes an edit that resolves the problem without changing the code’s functionality.
AI CodeFix currently uses space.vars.SQS\_20253\_Supported\_LLM\_version your own [Azure OpenAI LLM Service model](https://learn.microsoft.com/en-us/azure/ai-services/openai/concepts/models?tabs=global-standard%2Cstandard-chat-completions), to suggest fixes for a select set of rules in Java, JavaScript, TypeScript, Python, HTML, CSS, C#, and C++. To learn more about which rules are eligible for AI CodeFix, please see[#ai-codefix-rules](https://docs.sonarsource.com/sonarqube-server/2025.3/user-guide/rules/rules-for-ai-codefix#ai-codefix-rules "mention").
## Sharing your code with Sonar
When you select a self-hosted LLM, your code stays within your network. However, Sonar’s AI CodeFix service needs to send the latest prompts and supported rule descriptions therefore, your instance of SonarQube server will still need internet connectivity.
If you use Sonar’s AI CodeFix LLM, the affected code snippet will be sent by the AI CodeFix service to the selected LLM. Service agreements with Sonar’s LLMs prevent your code from being used to train those models.
For details about terms and conditions, please refer to the [AI CodeFix terms](https://www.sonarsource.com/legal/ai-codefix-terms/) in our [Legal Documentation](https://www.sonarsource.com/legal/).
## Enabling AI-generated fix suggestions
As an Instance Admin, you can enable or disable AI-generated fix suggestions on your projects. To enable AI CodeFix:
1. Go to **Administration** > **Configuration** > **General Settings** > **AI CodeFix** and select **Enable AI CodeFix**.
2. Select your **Provider**:
* The default option is Sonar’s **OpenAI** which uses space.vars.SQS\_20253\_Recommended\_LLM\_version.
* To choose your own **Azure OpenAI** LLM:
1. Select **Self-hosted Bring Your Own Model**.
2. Provide your Azure OpenAI **Endpoint**. The endpoint URL should include the `deployment-id` and `api-version` parameters.\
Here is an example: `https://.openai.azure.com/openai/deployments//completions?api-version=`
3. Provide your Azure OpenAI **API Key**. For information about using Azure AI models, see the [Azure OpenAI Service documentation](https://learn.microsoft.com/en-us/azure/ai-services/openai/).
4. Optional for enhanced security: Navigate to **Configuration** > **General Settings** > **Security** and select **Enforce Azure OpenAI EndPoint Domain** to only accept service endpoint URL domains that terminate with `.openai.azure.com`. Please double-check your entry at Step 2.2.
3. Once AI CodeFix is enabled, choose either **All projects** or **Only selected projects:**
When choosing **Only selected projects**, add projects individually from the list to activate the feature. New projects will not be added automatically.
{% hint style="warning" %}
Sonar recommends using space.vars.SQS\_20253\_Recommended\_LLM\_version as your Azure OpenAI Service model because it produces the best results. Using other models may produce unexpected fix suggestions that have undesirable effects.
For more information on your choices, see the [Azure documentation on service models](https://learn.microsoft.com/en-us/azure/ai-services/openai/concepts/models?tabs=global-standard%2Cstandard-chat-completions).
{% endhint %}
{% hint style="info" %}
You’ll need a connection to the internet to access SonarQube Server’s AI CodeFix service.
The service is provided via api.sonarqube.io and has these static IP addresses:
* 99.83.135.55 (CIDR: 99.83.135.55/32)
* 15.197.164.24 (CIDR: 15.197.164.24/32)
{% endhint %}
Once enabled, developers can get AI-generated fix suggestions from the **Issues** page in their projects. See the [fixing](https://docs.sonarsource.com/sonarqube-server/2025.3/user-guide/issues/fixing "mention") page for more details.
### Disabling AI CodeFix
To disable AI CodeFix completely in SonarQube Server and hide the feature from all users, including Instance Admins, set the system property `sonar.ai.codefix.hidden` to `true`. For more information, see the[configuration-methods](https://docs.sonarsource.com/sonarqube-server/2025.3/server-installation/system-properties/configuration-methods "mention") page.
## Getting AI-generated fix suggestions
Once AI CodeFix is enabled, users will be able to select **Generate AI Fix** on eligible issues and copy/paste the fix into their IDE with the **Open in IDE** feature when using connected mode.
The easiest way to use AI CodeFix is by using AI CodeFix in your IDE. Simply open your project in SonarQube for [VS Code](https://app.gitbook.com/o/2ibCvzwZt86Nlk2zloB7/s/6LPRABg3ubAJhpfR5K0Y/ "mention") or SonarQube for [IntelliJ](https://app.gitbook.com/o/2ibCvzwZt86Nlk2zloB7/s/NvI4wotPmITyM0mnsmtp/ "mention"), and set up connected mode with SonarQube Server. In your IDE, select an issue marked with the  icon, open the **Rule description** > **AI CodeFix** tab, and select **Generate Fix**. A fix will be generated in the code editor and you’ll have a chance to **Apply** or **Decline** the suggestion.
* For IntelliJ, see [AI CodeFix #AI CodeFix in your IDE](https://app.gitbook.com/s/NvI4wotPmITyM0mnsmtp/ai-capabilities/ai-codefix#ai-codefix "mention").
* For VS Code, see [AI CodeFix #AI CodeFix in your IDE](https://app.gitbook.com/s/6LPRABg3ubAJhpfR5K0Y/ai-capabilities/ai-codefix#ai-codefix "mention").

## Usage limits
## Marking a project as containing AI-generated code
Sonar recognizes that AI-generated code should be monitored with additional quality standards and offers administrators a series of project labels and custom quality gate certifications described on the [overview](https://docs.sonarsource.com/sonarqube-server/2025.3/quality-standards-administration/ai-code-assurance/overview "mention") page.
