📣 @OpenAIDevs's GPT-6 family is expanding in GitHub Copilot with two additional models now generally available.
☀️ GPT-6 Sol: the balanced model for interactive and agentic coding.
🌕 GPT-6 Luna: a lightweight, cost-efficient model for smaller tasks and the lowest-cost option in the family.
Try them in the GitHub Copilot app or @code.

Just one engineer and a team of agents ported the GitHub Copilot agent runtime to Rust, shipping 800,000 lines of production code while retaining code quality. 🚀

A language model can perform well on a clean benchmark and still struggle with the cases that matter in real-world use.
Here are the evaluation practices that helped us move from promising prototype results to production. ✅

AI coding tools increase developer output. But growing pull request backlogs can easily overwhelm engineering teams, contributing to what’s known as “review fatigue.”
Here’s how to calibrate your workflows for agentic development. Improve prompts, use stacked pull requests, and recognize how the developer role is changing.

Most alt text checkers confirm that an accessible name exists, but not that it says anything useful. So alt="IMG_2847.png" passes, and so does the same rating text pasted onto five different star icons.
More than one in four images on the top million home pages have alt text that is missing, vague, or duplicated from a neighbor.
That's why we built an alt text plugin for the GitHub Accessibility Scanner.

A sneak peek at some of the speakers taking the stage at #GitHubUniverse# 2026 ⭐️
See you in October 👋
The September 2026 GitHub Monthly Enterprise Roundup is now available.
Explore how GitHub’s Agentic Engineering System helps enterprise teams use AI to accelerate software delivery while maintaining quality, security, governance, and human oversight.
This edition also highlights Project HydraFusion, along with Copilot’s expanding agent, app, CLI, SDK, IDE, and collaboration experiences.
We cover three priorities for enterprise leaders:
• Build an agentic engineering operating model
• Measure adoption by outcomes, not output
• Embed quality, security, and human approval into AI-assisted workflows
Scale a more productive, secure, and resilient engineering system.

Be honest. How many tabs do you have open alongside your pull request? 👀
Sometimes you need context or answers to questions outside the platform, but GitHub agent apps can bring that context where you already are.
You can use services you depend on, like Amplitude, Endor Labs, LaunchDarkly, and PagerDuty, without ever leaving GitHub. 👇

Wouldn't be #GitHubUniverse# without a hackable badge 🧑💻
Grab your in-person pass and secure your badge
A much-needed refresh of the repo pull requests page landed in public preview yesterday. Very much in line with the rework we did on earlier this year: queries that can do AND/OR and nesting, content assist while you type, a filter sidebar, a compact mode, and check status and unread updates inline. We've all got a deluge of PRs these days, so we're working to make them easier to manage.
Try it out and give us feedback!
