GitHub Enables Copilot Models by Default for Business and Enterprise

As the new policy takes effect on August 26, 2026 ▸ github.blog • 1, organizations have a clear understanding of how the default enablement policy will impact their use of Copilot models.

Implementation Details

The default enablement policy for Copilot models on Business and Enterprise plans allows organizations to access new models as they become available, with a single control to opt-out ◉ github.blog · 1. This means that models which haven’t been explicitly configured will be relabeled from “unconfigured” to “inherits default” and will begin following the organization's policy setting.

According to the policy, if the organization's policy is enabled, those models become available to users ◉ github.blog · 1. Explicit choices for model enablement or disablement are preserved, ensuring that organizations have control over which models are used.

Exclusions and Exceptions

Open-weight models, such as DeepSeek and Kimi K2.7, are excluded from the default enablement policy ◉ github.blog · 1. Additionally, models not covered by GitHub's data retention agreement, such as Fable 5, are also excluded.

These exclusions ensure that organizations have control over which models are used and can opt-out of using certain models if needed ◉ github.blog · 1.
