🌌 GPT-6 Astra from OpenAI is now generally available in GitHub Copilot. This new model is designed for long-horizon, autonomous coding and agentic tasks. Our internal testing shows 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 extensive coding jobs with fewer steps than prior OpenAI models. Try it out in the GitHub Copilot app, CLI, or Visual Studio Code. 🚀 https://lnkd.in/es9nB7A8

Join us for the first-ever GitHub Copilot Day! 📅 Hear directly from the people building Copilot and learn more about Project HydraFusion, our new research preview that delivers frontier intelligence through runtime orchestration.

Open source can feel intimidating when you’re staring at a mature repository with thousands of stars and no idea where to start. In this episode of Open Source Friday, Andrea Griffiths sits down with ✨Angela W., an engineer on GitHub’s Copilot platform, to walk through a first contribution from repository discovery to pull request. They cover finding a `good first issue`, reading `README` and `CONTRIBUTING.md`, forking and syncing a repository, creating a draft pull request, navigating CI checks, and setting realistic expectations with maintainers. They also discuss using Copilot responsibly. If you want another human to review your work, you need to read it first. Stay through the end for a step-by-step beginner walkthrough. Then tell us: what was the first open source project you contributed to, and why?

4.9 percentage points higher verified task quality. 67% lower estimated cost. Project HydraFusion delivered those results against Claude Opus 5 on Terminal-Bench 2.1 in controlled offline evaluations. HydraFusion orchestrates the models and workflow for each coding task. You select it like any other model. Try HydraFusion through /experimental in GitHub Copilot CLI. https://lnkd.in/esguKUf4
