{% data variables.product.prodname_copilot %} supports a range of AI models. Different models have different strengths. For example, some prioritize low latency, while others are optimized for complex reasoning or large context windows. For a full list of supported models, see AUTOTITLE.
Depending on the surface you're using, your plan, and any policies your organization or enterprise has set, you can often choose which model handles your request, or let {% data variables.copilot.copilot_auto_model_selection_short %} choose one for you. Model choice affects the speed, cost, and quality of your results, so understanding your options helps you get the most out of every feature.
In addition, {% data variables.product.prodname_copilot_short %} also has utility models that run automatically in the background, and for {% data variables.copilot.copilot_business_short %} and {% data variables.copilot.copilot_enterprise_short %}, base and long-term support (LTS) models for extended stability.
When you're using {% data variables.product.prodname_copilot_short %}, whether that's on {% data variables.product.github %}, {% data variables.copilot.copilot_cli_short %}, the {% data variables.copilot.github_copilot_app %} and supported IDEs, you can select the model that best suits your task. For guidance on which model fits common tasks, such as general-purpose coding, large-scale refactors, or documentation writing, see AUTOTITLE.
The models you see in {% data variables.product.prodname_copilot_short %} depend on several factors:
- Your plan. Some models are available on all plans, while others, such as premium models, require a paid plan. See AUTOTITLE.
- The {% data variables.product.prodname_copilot_short %} surface or client you're using. Not every model is available in every IDE, on {% data variables.product.github %}, in {% data variables.copilot.copilot_cli_short %}, or in the {% data variables.copilot.github_copilot_app %}. See AUTOTITLE.
- Administrator policies. If you're part of an organization or enterprise, administrators can enable or disable specific models, which affects what you and {% data variables.copilot.copilot_auto_model_selection_short %} can use. See AUTOTITLE.
- Model availability over time. Providers periodically release new models and retire older ones, so the specific models available to you can change. Check AUTOTITLE for the current list.
Rather than requiring you to track every model's strengths yourself, you can select Auto in the model picker. {% data variables.copilot.copilot_auto_model_selection_short_cap_a %} then routes your request to an appropriate supported model based on the complexity of your task and real-time model availability. See AUTOTITLE.
With bring your own key (BYOK), you (or your enterprise) can connect a custom or provider-hosted model to {% data variables.product.prodname_copilot_short %}. Availability depends on the mechanism you use and the client you're working in. See AUTOTITLE.
Some {% data variables.product.prodname_copilot_short %} features, such as generating a commit message or a chat session title, run on small utility models that work automatically in the background. Utility models aren't part of the model picker, and you can't select them directly. See AUTOTITLE.
{% data variables.copilot.copilot_business_short %} and {% data variables.copilot.copilot_enterprise_short %} accounts have access to two additional model designations:
- A base model is used automatically when no other model is enabled for the account.
- A long-term support (LTS) model is supported for a defined extended period of time, currently one year from its designation date.
See AUTOTITLE.
