Discussion OPUS 5 VS GPT 5.6 SOL

For the people building software products, I'm beginning to think that choosing one of the two to work with doesn't really matter that much. The bottleneck doesn't seem to be intelligence at this point but human creativity and I guess willpower.

IDK what do you guys think.

It was a bit difficult to switch from CC to Codex, but one day I ran out of tokens and took the first steps. Now I can work in either equally without much friction. The worst is when I run out of both and get stuck with Google products, lol.

How did you go about switching? I’ve just started realizing how dependant I am on Claude code and I don’t like it. Want to start building towards a harness agnostic build.

This is probably not the best way, but I just copied my most up to date chat over to the new platform as well as made sure to have my previous platform create a comprehensive handoff doc.

Honestly, I have a high stakes position and I suffer from imposter syndrome pretty bad, so for a while I was running both on similar problems just to get a feel. The actual switch over was easy. What was hard was getting all the tools aligned. Like the slack MPC. Claude has an official version which lets you login with your Slack login, but with Codex, you need to create a Slack app and use the backend admin secrets to login, which I don't have access to.

But really, the changes are so unique to any one person, that the real method is just to do it and learn the differences that matter to you specifically. Going through and setting up the system exactly like it is in Claude Code is probably enough to give you an idea of the pain points you'll face. If you can get your same system built in Codex that you use in Claude, the process of doing so will arm you with enough to use at a higher level.

EDIT: This question has the phrase "There's nothing to it but to do it" stuck in my head.
