> 5.2 codex or Claude Code with Opus 4.5 a try

Is using these same models but with GitHub Copilot or Replit equally capable as / comparable to using the respective first-party CLIs?

I don’t think so. My favorite tool is Codex with the 5.2-codex model. I use Github Copilot and Codex at work and Codex and Cursor at home. Codex is better for harder and bigger tasks. I’ll use Copilot or Cursor for small easy things. I think Codex is better than Claude Code as well.

I have GH Copilot from work and a personal Claude Code max subscription and have noticed a difference in quality if I feed the same input prompts/requirements/spec/rules.md to Claude Code cli and GH Copilot, both using Opus 4.5, where Claude Code CLI gives better results.

Maybe there's more going on at inference time with Claude Code cli?
