alt Hacker NewsThe power of Opus isn't just the model, it's in the harness too.
You can try it by using Opus through Github Copilot vs official Anthropic tools. You'll get very different results and experience (in my opinion).

open source harnesses are also improving rapidly.
Some people would claim they are already far better than CC and Codex.

I’ve only used Opus in GitHub copilot and was hugely underwhelmed. It was barely usable. Are you saying it’s better with the official Anthropic tools?

GitHub Copilot in vscode has two ways to access Opus: the Copilot harness or the Claude Code Agent SDK within Copilot.
And that's if we assume that the vscode GHCP default Agent ("Local") is the same as the "Copilot CLI" one that is also selectable in vscode. I have not tried that one.
A few weeks ago the Claude Code Agent SDK was much better than the default Copilot Agent, but nowadays I am not sure.
