Supported AI models in GitHub Copilot

GitHub Copilot supports multiple models, each with different strengths. Some models prioritize speed and cost-efficiency, while others are optimized for accuracy, reasoning, or working with multimodal inputs (like images and code together).

Depending on your Copilot plan and where you're using it—such as GitHub.com or an IDE—you may have access to different models.

For all of the default AI models, input prompts and output completions run through GitHub Copilot's content filters for harmful, offensive, or off-topic content, and for public code matching when enabled.

Supported AI models in Copilot

This table lists the AI models available in Copilot, along with their release status and availability in different modes.

Supported AI models in Auto model selection

This table lists the supported AI models for Auto model selection. Available models may be limited by model policies. See About Copilot auto model selection.

Models with extended capabilities

The latest Copilot models support the following extended capabilities.

• 1 million token context window: Allows the model to process significantly more content in a single session. This is useful when working across large codebases, long documents, or complex multi-file projects. When you select a supported model, you can choose between the default context size or the extended (1 million token) context.
• Configurable reasoning levels: Controls the depth of the model's reasoning process before it generates a response. When you select a supported model, you can choose which reasoning level you want to use. Higher reasoning levels can improve the quality of responses to complex problems.

Choosing a larger context window or higher reasoning will impact AI credits consumption; more tokens will be consumed, so more credits will be used. For this reason, we recommend that you use the regular context window and regular reasoning by default, selecting the larger context window and higher reasoning for more complex tasks only.

Model retirement history

The following table lists AI models that are retired or scheduled for retirement from Copilot, along with their retirement dates and suggested alternatives.

Supported AI models per client

The following table shows which models are available in each client.

Minimum IDE versions for recent models

Some Copilot models require minimum versions of supported IDEs or Copilot extensions or plugins. The table below lists the minimum versions known from changelog entries or provided release guidance. This information is tentative and subject to change as model support rolls out. For best results, keep your IDE and Copilot extension or plugin updated to the latest available version.

Supported AI models per Copilot plan

The following table shows which AI models are available in each Copilot plan. For more information about the plans, see Plans for GitHub Copilot.

Fallback and long-term support (LTS) models

For more information about fallback and LTS models, see Base and long-term support (LTS) models.

Evaluation models

GitHub Copilot offers access to evaluation models.

Evaluation models may appear in product with codenames rather than official model or provider names. These models come from, or are fine-tuned by, one or more of the following providers: Microsoft, OpenAI, Anthropic, Google. Data handling for each provider is limited to GitHub's existing agreement with that provider, and evaluation models undergo GitHub and Microsoft testing and verification before release.

Evaluation models may be added, updated, or removed without notice. Availability and rate limits may differ from generally available models.

Access to evaluation models in auto model selection for users Copilot plans for individuals is governed by a policy. To disable evaluation models:

1. In the upper-right corner of any page on GitHub, click your profile picture, then click Settings.
2. At the top of the page, click AI controls.
3. For the Evaluation models in Copilot auto model selection setting, select Disabled from the dropdown.

Utility models

Utility models power background features across surfaces, and cannot be disabled or selected in the model picker. See Utility models.

The following models are currently used as utility models:

• GPT-4o mini
• GPT-4o
• GPT-4.1
• GPT-5.4 nano
