GitHub Copilot

This update brings support for enterprise-managed sandbox policies, cross-file cursor jumps for next edit suggestions, global project context in chat, enterprise policy diagnostics, and a new connection between terminal Copilot CLI sessions and JetBrains IDEs. It also improves model selection, the chat experience, and reliability across MCP servers and agent sessions. What's new Enterprise-managed sandbox policies in public preview Enterprise administrators can now centrally configure sandbox behavior for GitHub Copilot in JetBrains IDEs. Managed policies can control sandbox enablement, filesystem and network access, proxy settings, developer-tool access, macOS Keychain access, and more. Managed restrictions take precedence over user settings. Copilot locks affected controls in the IDE and identifies settings managed by your organization, helping administrators enforce consistent development environment boundaries. The sandbox settings under GitHub Copilot > Sandbox are visible when your organization enables the Editor Preview feature flag or configures a managed setting to enable or disable the sandbox. If neither condition applies, the sandbox settings do not appear.

GPT-6 Astra from OpenAI is now available in GitHub Copilot. OpenAI's latest general-purpose model, GPT-6 Astra, is designed for long-horizon, autonomous coding and agentic tasks. In our internal testing, GPT-6 Astra stood out for how it works, not just what it produces: it plans and validates as it goes, batches diagnosis with verification, and independently confirms its results before declaring a task done. That translated into stronger performance on long-horizon coding tasks with fewer steps than prior OpenAI models. This model is billed at provider list pricing under usage-based billing. See pricing for GitHub Copilot models and requests for details. Availability in GitHub Copilot GPT-6 Astra is available to Copilot Pro+, Max, Business, and Enterprise users. You can select the model in the model picker in:

Copilot Enterprise and Copilot Business administrators may need to enable access to the alternative models through their model policies in Copilot settings. As an administrator, you can verify availability in your organization or enterprise Copilot model settings and confirm that the policy is enabled for the specific model. Once enabled, users will see the model in the Copilot Chat model selector in supported GitHub Copilot experiences. No action is required to remove the models after they have been deprecated.

The GitHub Copilot app and Copilot CLI now respect content exclusion policies configured by enterprise, organization, and repository administrators.

You can now set your preferred GitHub Copilot model as the default for new conversations through enterprise-managed settings. This lets you choose the default model that best fits your workflows. You can also customize the default by enterprise team, assigning a different default model based on team membership. Set the model key as overridable and update team configuration files in team-mappings.json so that enterprise teams can choose their own preferred default model. All other users inherit your enterprise default. Model defaults in managed settings are generally available with Copilot Business and Copilot Enterprise in the GitHub Copilot app, Copilot CLI, and Visual Studio Code.

Claude Fable 5.1 from Anthropic is now available in GitHub Copilot. The latest model in Anthropic's Mythos class, Claude Fable 5.1 is designed for long-horizon, autonomous coding and knowledge-work tasks. In our internal testing, Claude Fable 5.1 demonstrated strong performance on substantial, long-running coding tasks, including deep codebase research, feature development, and complex agentic workflows. Unlike other Claude models in GitHub Copilot, Claude Fable 5.1 requires data retention by default to operate Anthropic's safety classifiers. Zero data retention access is available for certain eligible enterprise customers. Continue reading for more details. This model is billed at provider list pricing under usage-based billing.

Copilot now tells you when a pull request is ready to approve, and admins can authorize it to sign off on approval. The ability for Copilot to approve is off by default and configurable at the enterprise, organization, and repository level. The approval assessments will now appear as a part of the overview comment in every Copilot review. This feature is available in public preview to GitHub Copilot Pro, Pro+, Max, Business, and Enterprise plans. ✅ Approval assessments Every Copilot code review now includes an approval assessment in the overview comment. The assessment signals whether Copilot considers the pull request ready to approve, giving you an at-a-glance read on its judgment alongside its detailed comments. An approval assessment alone does not count toward merge requirements. Copilot's determination is surfaced so you can decide how to act on it. ⚙️ Turning on approvals By default, Copilot will not approve pull requests. When enabled, Copilot can submit an approval that counts toward the repository's required-approvals rule. If new commits are pushed after Copilot approves, its approval is dismissed just like a human reviewer's, and you can request a new review from

You can now set an optional expiration date on an individual user budget, and GitHub removes the budget on that date. This capability is generally available. The user then falls back to the next budget that applies to them (i.e., their cost center per-user budget or otherwise your universal budget). Previously, you had to remove every temporary budget override by hand, creating recurring cleanup work at enterprise scale. When you create or edit an individual user budget, you can choose:

• No expiration, which is the default and matches current behavior.
• Expiration at the start of the next billing cycle.
• Expiration on a specific date. You can change or clear an expiration date at any time. Set an expiration date in your billing settings, or use the expires_at field in the Budgets REST API when you create or update a budget. Expiration dates are available for the GitHub Copilot Business and Copilot Enterprise plans.

We have updated how model access is determined for Copilot users who hold seats in more than one organization. To keep billing and governance in sync, your model access is now determined only by the organization paying for your usage. What's changing Before this change, if you had Copilot seats in more than one organization, you could use a model as long as any of your organizations enabled it. With this update, your billing organization decides model access. You can find this organization under "Usage billed to" in the Copilot features page . For more information about how policies apply, read the GitHub Copilot policy documentation . What isn't changing If your Copilot access comes entirely through an enterprise or its organizations, your model access will not be impacted by this update. Table of Contents

This changelog covers VS Code v1.132 through v1.135 , shipped throughout August 2026. These releases make it easier to organize agent sessions, review changes, and navigate long conversations. Agent Host, the integrated browser, and dictation also get updates to support more ways of working in VS Code. Agent sessions and workflows The Agents window adds more ways to organize related chats, follow agent activity, and move between prompts and their file changes.

• Arrange chats side by side: Keep multiple chats visible in horizontal or vertical groups to compare results or follow your agent's work, with the layout restored when you return to the session.
• Open a side-conversation: Type /btw to open a side chat that shares the primary chat's context and prompt cache while it continues running.
• Navigate the chat conversation: Use the prompt timeline control from the transcript gutter to easily navigate to specific prompts in chat and review the related file changes.
• Install portable agent plugins: Install agent customizations from plugins that follow the Agent Plugins 1.0 standard across VS Code and other compatible agent clients.

To provide a strong, consistent Copilot experience, we're making three separate, upcoming changes to Copilot policies and billing.
