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. ⬇️

Kimi K2.7 Code is now generally available for Copilot Business and Enterprise accounts. This is the first open-weight model offered as a selectable option in the Copilot model picker, providing more choice for developers at a lower cost.
Plan administrators can enable the Kimi K2.7 Code policy in Copilot settings to make it available for their organization.

Feedback heard: GitHub Copilot launched our first open-weight model yesterday - Kimi K2.7 Code 🎉
Keep telling us how to make your @github experience better, and we'll keep listening!
🆕 @Kimi_Moonshot's Kimi K2.7 Code is now generally available in GitHub Copilot.
This is the first open-weight model offered as a selectable option in the Copilot model picker. 🎉
Early testing shows Kimi K2.7 is a lower-cost option with strong performance comparable to highly popular frontier models.
Try it out now in @code and look out for it in more GitHub Copilot surfaces. 👇

A coworker and I just published a post on VS Code’s blog about the recent token efficiency improvements we’ve made in GitHub Copilot Chat.
Please give it a read and let me know what you think!

Claude Fable 5 is now rolling out for @code, GitHub Copilot CLI, and GitHub Copilot app developers!
📣 Claude Fable 5, the first in @AnthropicAI's Mythos model class, is now generally available and rolling out in GitHub Copilot.
It is designed for long-horizon, autonomous coding and knowledge-work tasks. Try it out in @code or the GitHub Copilot app. ⬇️

In the age of AI slop, some of us are still making things by hand, I promise ❤️ Octocat for the new GitHub Copilot App was modeled, rigged, and animated in Blender...

🆕 @OpenAIDevs GPT-5.5 is now generally available and rolling out in GitHub Copilot.
Our early testing shows
➡️ It delivers its strongest performance on complex agentic coding tasks
➡️ It resolves real-world coding challenges previous GPT models couldn’t
Try it out in Copilot CLI or @code. 👇

@GitHub plugin in the Codex app.
Fascinating data from the Copilot team! I do want to plug how high-performing selecting auto is, which allows Copilot to select the right model for you. Plus, it gets you a 10% discount on PRUs!
Hot take from looking at @github Copilot telemetry: benchmarks make coding models look wildly different. Production workflows make them look much more similar. 👀
We looked at 23M+ Copilot requests and examined one simple metric: code survivability.

Copilot CLI can now use memory 🧠. We also published a blog about our challenges and solution.

🚀 We’re now launching new models in Copilot straight to GA.
We heard the feedback: public preview was frustrating and slowed adoption.
No compromise on safety or quality: We moved the same rigorous reviews pre-launch so models can ship GA on day one.
GPT-5.2-Codex was the first. More coming!
.@OpenAI’s GPT-5.2-Codex is now rolling out in GitHub Copilot.
This model excels at large code changes like refactors or migrations, and has improved performance in Windows environments. Try it out in @code. github.blog/changelog/2026-0…
I'm on substack now! Kicking things off with everything i've figured out about public speaking - spoiler: it's mostly just being excited and talking in relatable ways.

Use AI to reduce the toil and focus on what you actually enjoy in development!
Awesome guide from @phazonoverload on using @GitHub Models in Actions to:
- Auto-reply to bug reports
- Write release notes from PRs
- Summarize + prioritize weekly issues

"By making high-quality inference a free default for every developer on @github, GitHub Models gets rid of the biggest blocker to OSS AI adoption. And that opens the door to more contributions, faster onboarding, and happier users." - @sjgoedecke
github.blog/ai-and-ml/llms/s…
Really cool GitHub Models use case from @slicknet that's especially helpful for OSS maintainers - Given a GitHub repository and release, it creates a social post summarizing the key changes and improvements:

"When intent approaches perfect clarity, resistance approaches zero."
Great line from a substack someone just sent me regarding AI agent design, but I can also see this in a textbook about product management ♥️
