alt Hacker NewsWorking at Microsoft, I've just now hooked up to Claude Code (my department was not permitted to use it previously), through something called "Agent Maestro", a vscode extension which I guess pipes claude code API requets to our internally hosted Claude models, including Opus 4.6.
I do wonder if there is going to be much of a difference between using Claude Code vs. Copilot CLI when using the same models.

Is this an indictment of OpenAI's models -- that Microsoft has access to through their investment?
I honestly don’t think the models are as important as people tend to believe. More important is how the models are given tools - find, grep, git, test runners, …
Compare their system prompts and the agent harness logic. It's 99% of what makes the agent useful, and it can be quite different.

I’m also at MS, not (yet?) using Claude Code at work and pondering precisely the same question.
