@akashc777 @madebygps Small feature, massive workflow win.

[Microsoft Developer @msdev]

GitHub CLI now lets you attach local images and videos with --attach, so you can add media directly to issues, pull requests, and comments without leaving the command line.

[Perplexity @perplexity_ai]

Portable Computer is now available on Windows PCs with @NVIDIA RTX GPUs.

Run the harness, agents, and models locally on your PC.

Work with local files and connected apps without sending tasks to the cloud. Use frontier cloud models when needed.

[Microsoft Developer @msdev]

Clear your calendars tomorrow for four hours of GitHub Copilot.

We’ll get into agents, models, the CLI, VS Code, live demos, new stuff, and plenty of code along the way.

Tune in and hang out with us.

Try ThinkingBox 👇

https://t.co/MNsxglGp9o contains the runtime. 

https://t.co/DeiNlkGeSG contains the benchmark tasks, synthetic records, and MCP servers.

[Microsoft Developer @msdev]

We built ThinkingBox to measure whether agents actually finish the job.

ThinkingBox runs agents in isolated, stateful tool environments, lets simulated users answer follow-up questions, and inspects the side effects left behind.

[GitHub @github]

Claude Fable 5.1, the latest in @AnthropicAI's Mythos model class, is now generally available in GitHub Copilot.

In our testing it showed strong performance on
➡️ long-running coding tasks
➡️ deep codebase research
➡️ complex agentic workflows

Try it out in the GitHub Copilot app, CLI or @code.

This is the story of how @code got here, told by the people who built it and the developers who helped shape it.

Then get under the hood on TokenOps’ architecture and run-scoped governance 👇
https://t.co/SQnIQUZfU2

[Microsoft Developer @msdev]

Who spent all the tokens? 👀

TokenOps gives multi-agent workflows one shared, run-scoped budget, with policies that can step in before the next model or tool call executes.

The result is real-time control over spend and agent behavior while the run is still happening.

@Azure @SpaceXAI Happy building! 🥳

@jbseltzer @ahejlsberg What are you liking most about it?

[Microsoft Developer @msdev]

In 2025, TypeScript became the most-used language on GitHub. Then came TypeScript 7, a native port built to be up to 10x faster.

Creator @ahejlsberg joins The Peterman Pod to unpack the move to Go, the technical tradeoffs, agentic AI, and more.

@saltyq @github @steipete Can't wait to hear your thoughts!

[Microsoft Developer @msdev]

OpenClaw went from a weekend project to one of @github's fastest-growing open source projects.

Six months in, @steipete and several maintainers share what they learned about scaling contributions, trust, code review, and security.
