• Actionable error message shown when GitHub API rate limit is hit during copilot update
• Add /rubber-duck command for adversarial feedback on code and designs
• Plugin slash commands (/plugin install, uninstall, update, marketplace add/remove/browse) now show immediate feedback while the operation is in progress
• Canceling a running shell command (Ctrl+C on a !command, or aborting an agent command — including in sandboxed and background-promoted shells) now terminates the whole process tree instead of leaving orphaned processes running
• Canvas providers can return file:// URLs in open results for local file previews
• Symlinked directories appear in /cwd completion suggestions
• In Azure DevOps-only repositories, the built-in GitHub MCP server now exposes only the web_search tool instead of being fully disabled
• Quota footer shows remaining requests as a rounded percentage
• /lsp show, /lsp test, and /lsp reload correctly discover project LSP config when the CLI is launched from a subdirectory
• MCP server timeout configuration is preserved after tools list changes
• /skills add and /skills remove correctly handle paths wrapped in quotes (e.g., from Windows Explorer "Copy as path")
• Running copilot with an unquoted multi-word prompt now shows a helpful "quote your prompt" hint instead of a raw commander error
• Default networking transport is now HTTP/1.1, improving reliability on some network paths. Opt into HTTP/2 with COPILOT_ENABLE_HTTP2=1.
• Plugins auto-installed from repository settings no longer leak into user global config
• Grep tool correctly handles tsx and jsx as file type filters
• COPILOT_HOME is honored for the server discovery registry directory

• @-mention file search matches files regardless of query letter casing
• copilot plugin marketplace list now honors repo-level extraKnownMarketplaces settings from .github/copilot/settings.json
• Queued prompts in the footer are capped to a single line, preventing them from pushing session messages off screen
• MCP servers configured with npx --registry are no longer incorrectly blocked by policy
• Session no longer hangs indefinitely after an error occurs during internal event processing
• Installed plugins no longer include the .git directory from the plugin source repository
• New reasoning after tool calls appears at the bottom of the timeline instead of above earlier output
• Pasting text copied from a browser, editor, or terminal no longer leaves a stray empty line, broken box-drawing lines, or a misplaced cursor in the prompt
• preToolUse hook errors now deny the tool call instead of silently allowing execution
• Session resume works correctly after a crash that left partial data in the session log
• High-contrast diff backgrounds use darker colors to improve text readability
• Add showTipsOnStartup setting to control whether startup tips are shown
• Surface the underlying reason (e.g. GitHub API rate limit) when SDK auth-token validation fails, instead of the misleading "Session was not created with authentication info or custom provider" message.
• /diff defaults to branch diff when there are no unstaged changes

Software developers are some of the most ambitious makers we serve. They push devices harder, ask more of their tools and expect their environment to help define the pace of modern software creation. Development today means longer running jobs, larger models and a growing need to prototype and iterate locally rather than paying for every cloud call. That is why we embarked on a project to build two new Surface devices designed specifically for the needs of these makers. Earlier this week, we introduced Surface Laptop Ultra, a high-performance laptop built for developers, creators and technical professionals who need serious performance wherever they work. Today at Microsoft Build, we are introducing Surface RTX Spark Dev Box, a compact developer PC engineered with NVIDIA RTX Spark superchip and built on the Windows developer platform, designed for local-first AI development. Surface RTX Spark Dev Box is for developers who want to prototype, fine-tune and run capable models on their desk, and reach for the cloud when the work calls for it. Together, Surface Laptop Ultra and Surface RTX Spark Dev Box represent the next step for Surface: purpose-built devices for the people building what’s next. https://youtu.be/VlAI1_JkXL4?si=t7VDdKcaaxgdXBDW

A new category of Surface, built for developers

The way developers build software is fundamentally changing. AI models are growing in capability and complexity, agentic workflows demand sustained compute, and every iteration can incur cloud costs, even when the work doesn’t require state-of-the-art models. Surface RTX Spark Dev Box changes that equation. It’s a purpose-built Windows AI developer box that puts up to 1 petaflop of AI compute directly on the desk. By bringing powerful AI compute to the edge, developers can reserve frontier model calls for truly frontier problems and handle the rest on their own hardware. The result is a development workflow that can be more efficient and responsive, with developers in control of where their compute dollars go.

Sustained AI performance in a compact form factor

At the heart of this new developer machine is the NVIDIA RTX Spark superchip, combining a powerful NVIDIA Blackwell RTX GPU and an ultra-efficient NVIDIA Grace CPU to deliver up to 1 petaflop of AI compute with 128 GB of unified memory. That’s enough compute power to run 120B+ parameter models with 1 million token context locally at interactive speeds or fine-tune models that previously required cloud GPU instancesⁱ. With an aluminum chassis engineered to double as a heatsink, Surface RTX Spark Dev Box is designed for the workloads that matter most to developers: long-running training jobs, large model inference and complex agentic pipelines that benefit from consistent, sustained performance.

Built for the tools and workflows developers already use, out of the box

Surface RTX Spark Dev Box ships with Windows 11 Pro pre-configured for developers at the image level. This brings a purposeful set of defaults, preinstalled tools and tuned settings so the development environment is the default from first sign-in. The setup keeps developers in their workflow: dark theme, taskbar simplified for development, Widgets removed, Do Not Disturb on. Developer Mode is enabled. PowerShell 7 is the default shell. Under the hood, WSL 2 is configured with GPU passthrough and CUDA support. VS Code, GitHub Copilot, Git, Python and Node.js are installed. Your favorite IDEs, agents, coding assistants, frameworks and libraries all work on Surface RTX Spark Dev Box, whether you prefer the Windows side or WSL. Surface RTX Spark Dev Box is also a world class entry point to the rest of the Microsoft AI stack. AI Toolkit for VS Code brings model conversion, fine-tuning and evaluation into the editor developers already use. Windows ML with TensorRT, and Windows Copilot Runtime give you a consistent local inference surface. Microsoft Foundry connects local prototyping to production deployment, so the model you tune locally ships through the same tools and identity you use every day. GitHub Copilot scales from CLI to enterprise on the same machine. That is what we mean by best Microsoft experience for developers: the local box, the OS, the developer tools and the cloud platform working as one stack.

Secure by design

For developers working with sensitive models, proprietary data and valuable IP, security isn’t optional. It’s foundational. The powerful GPU and unified memory mean more of your models and IP can stay local and lets developers keep more of their models and data local. Surface RTX Spark Dev Box is built on chip-to-cloud security aligned with Microsoft’s Zero Trust principles:

• Secured-core PC architecture
• BitLocker encryption
• Microsoft Defender protection

For organizations, Surface RTX Spark Dev Box integrates with Entra ID and Intune for management and governance at scale. With Surface Laptop Ultra and Surface RTX Spark Dev Box, we’re expanding the Surface line with two products built specifically for makers. Surface Laptop Ultra is built for high-performance work that moves with you, from compiling and debugging to creative production and AI experimentation, while Surface RTX Spark Dev Box is built for the local compute developers need when models, agents and long-running workloads belong on the desk. Different form factors, same direction: giving developers the best option and more choice in where and how they build.
