What happened
Back to changelog August 2026 brought more control over how GitHub Copilot reasons, which models you use, how teams share specialized agents, and when you ask for a code review. The details below come from GitHub.
This report is assembled from the verified claims listed by the publishing pipeline, and states nothing beyond them.
What's new
- Highlights Here’s what’s new with GitHub Copilot in Visual Studio 2026.
- Check the Insiders channel for the latest: – Organization-level custom agents : GitHub organization and enterprise owners can publish custom agents for use across repositories in their organization.
- Visual Studio automatically detects these agents and shows both their descriptions and organization source in the agent picker.
- This functionality requires a GitHub organization.
Why it matters
– Access your Copilot usage : Open the context window from the Copilot prompt box, then select View all Copilot usage to see your full plan details. Refined notifications also make it clearer when you are approaching a limit and what options are available. – Adjust model thinking effort to match your task : Supported models now offer Low , Medium , and High thinking effort controls. Use lower effort for straightforward work or higher effort for complex debugging, algorithms, and architecture decisions.
Readers evaluating tools in this category should weigh the reported change against what they currently rely on.
Who should care
Developers and designers already working with this vendor are the most directly affected, along with teams comparing options in the same category.
Practical implications
This enables you to balance reasoning depth with token usage. – Better model control : Pin favorite models, collapse models you use less often, and select Manage models for a detailed view. The management view includes model capabilities, context window sizes, cost information, and controls for Copilot and custom models.
Anyone depending on this behaviour should confirm the specifics against the vendor documentation linked below before acting.
