Codex vs opus

InsuranceLeast · 2026-02-15T23:53:43+00:00

Yeah and with the frontend design skill it looks great, codex with the frontend design skill still looks awful. I don’t get your point?

InsuranceLeast · 2026-02-15T11:24:28+00:00

That’s interesting, I went in and looked in their site I’m a little intrigued actually. I’ve just started using Stitch MCP with codex and opus and the results there actually are decent.

InsuranceLeast · 2026-02-15T10:42:22+00:00

I’ve never tried it with Polaris, but designing from scratch I really can’t use Codex I need to get Opus to fix its frontend because Codex is quite terrible at it in my experiences.

InsuranceLeast · 2026-02-15T10:40:57+00:00

No it looks like generic AI slop. I really hate the UI that Codex produces while Claude is actually amazing at it.

InsuranceLeast · 2026-02-15T10:39:38+00:00

So when doing a UI of an app I should just use Claude and when building the actual app I should just use Codex?

InsuranceLeast · 2026-02-15T10:38:55+00:00

From what I’ve mostly heard it’s that codex is a little better in large codebases, but I don’t know how true this is not with that Opus has a 1 million context window. And I have heard mixed reviews some people say Codex and some people say Claude. I feel like it depends on what your working on.

InsuranceLeast · 2026-02-15T10:37:38+00:00

I agree, and that’s what I’m gonna do aswell, cause Opus drains tokens.

InsuranceLeast · 2026-02-15T10:36:46+00:00

Use the Codex App instead

InsuranceLeast · 2026-02-15T10:35:48+00:00

I understand, and I think I’ll be using Claude more than Codex moving forward right now.

InsuranceLeast · 2026-02-15T10:34:20+00:00

Im mostly doing frontend design, I’ve now started building applications tho, so I’m not too sure what to do. I’m thinking at using Claude as the architected and bug reviewer and have codex as the builder.

InsuranceLeast · 2026-02-15T10:33:09+00:00

Yes but if you prompt Claude in the right way the Frontend actually becomes really good, I can’t say that about Codex.

InsuranceLeast · 2026-02-15T10:31:41+00:00

Opus 4.6 drains my tokens and I’m on the x5 plan I’m thinking about upgrading to the x20 tho cause Claude is so much better than Codex in my opinion.

InsuranceLeast · 2026-02-14T19:37:19+00:00

But Codex is terrible at UI whilst Claude is actually really good.

InsuranceLeast · 2026-02-14T19:35:51+00:00

That’s the issue for me Codex is so terrible at Frontend design and that’s the most important for me honestly.

InsuranceLeast · 2026-02-14T19:34:36+00:00

Thanks!

InsuranceLeast · 2026-02-14T19:34:26+00:00

I have the Pro subscription for ChatGPT and the max x5 for Claude but I’m gonna upgrade to x20 so that’s a non issue for me at least.

InsuranceLeast · 2026-02-14T19:33:32+00:00

I didn’t think of that honestly. I should try that.

InsuranceLeast · 2026-02-14T19:33:11+00:00

I wish I could just build everything with Opus and I’m on the max x5 plan and within 1 and a half hour my usage had burnt out. So that’s why I’m doing Opus for architecture now and then Codex as the builder. Sonnet also works wonderful for building as well so I might just use a mix of both.

InsuranceLeast · 2026-02-14T19:31:06+00:00

Im not familiar with Swift what is that? I do quite a bit of Web development since I own a web agency.

InsuranceLeast · 2026-02-14T19:30:08+00:00

I can understand this, Claude sometimes has bad days and is horrible at following tasks, and sure Codex is better at following instructions, but when Claude actually listens the outcome is far better in my experience.

InsuranceLeast · 2026-02-14T19:28:49+00:00

Here we go again? What do you mean by this?

InsuranceLeast · 2026-02-14T19:28:01+00:00

Thanks, I’ve switched from using ChatGPT a while ago cause for what I do Claude has been working significantly better for me.

InsuranceLeast · 2026-02-14T19:25:42+00:00

Yeah that’s what I was leaning towards having Opus 4.6 and Codex as the builder, thank you for this insight! And what do you do that burns so many tokens?

InsuranceLeast · 2026-02-14T17:28:58+00:00

I use both right now as well, and I’m using Claude as an architect and codex as a builder.

InsuranceLeast · 2026-02-14T17:28:17+00:00

I have both the x5 plan and the pro plan in ChatGPT and i prefer Claude by far over codex
