AI Model Lifecycle PM for @github Copilot. Building tools for AI developers. Potluck enthusiast. Laughs often. Views my own.

[Cameron Foxly @CameronFoxly]

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. 👇

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!

[Kyle Daigle @kdaigle]

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.

[Mario Rodriguez @mariorod1]

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!

[GitHub @github]

.@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. https://t.co/TnkOVixjUI

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

[Kate Catlin @Kate_Catlin]

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 ♥️

[Kate Catlin @Kate_Catlin]

I vibe-coded an AI-powered GitHub Action that:
- Scrapes Discussions daily
- Uses GitHub Models to classify posts
- Auto-opens issues for bugs

Copy it to catch community bugs early - and plug AI into your workflow with GitHub Models!

We're excited to share our new project at GitHub Next called "Continuous AI"

https://t.co/t87mM5kJDz

Some details in thread!

[Kate Catlin @Kate_Catlin]

“Continuous AI” is my favorite new industry term. ✨ It means any use of automated AI to support software collaboration, on any platform.

Great list from the @GitHubNext team of "awesome" cross-industry examples:

GitHub's AI developer tools now support pay-as-you-go or bring-your-own-key.

Pay us. Pay OpenAI. Pay Azure.
Just don’t ship untested AI outputs 🙏

@github AI evaluations have gone local 😎 You can now run:
> gh models eval [your .prompt.yml file]
from your CLI and get the same evaluators you’d use in the GitHub Models UI.
