趋势解读：Expanded technical preview availability for the GitHub Copilot，聚焦 Agent 工作流

The GitHub Copilot app technical preview is now available to all existing Copilot Pro, Pro+, Business, and Enterprise customers. Download the Copilot app for Windows, macOS, or Linux to get started. Copilot Free users and customers not yet on Copilot can join the waitlist to be notified when broader access becomes available. Existing Pro+ customers can upgrade to the new Copilot Max plan for greater included usage. This release is also where the app’s center of gravity shifts. As agents do more per session, the work that falls to you changes into managing their output: reading chat transcripts, hunting for the diff that matters, and repeating yourself to course-correct. The headline addition in this release, canvases, is our answer to that shift. Canvases give agent work a place to take shape, become visible, and get verified. All this happens alongside the chat where you steer it. The Copilot app is the desktop home for agent-native software development on GitHub. In one app you can: Start a session from an issue, pull request, prompt, or prior session, across all your connected repositories from a single My work view. Run parallel agent sessions, each on its own git worktree and branch, with isolated files, conversation, and task state. Start from any local folder, not just a git repository, and use it as context for new agent sessions, prototypes, explorations, or workflows. Review the plan and diff, then validate behavior in an integrated terminal and browser. Open a pull request that uses your team’s existing reviews, checks, and merge requirements, and let Agent Merge address review comments, fix failing checks, and merge when your conditions are met. Choose the model behind each session, connect external tools via MCP servers, and package recurring work as reusable skills and scheduled automations. Canvases are bidirectional work surfaces for humans and agents. The agent updates the canvas as it works, and you can edit, reorder, approve, or redirect work directly on that same surface. This is the beginning of agent experience (AX) in the Copilot app: interfaces designed not only for people to use, but for people and agents to operate together. The agent session remains where you instruct, discuss, and reason through ambiguity. Canvases are where that intent becomes visible work you can inspect, steer, and verify.
