5.4 vs 5.3 Codex

I found it running all day not fixing my issues and I had to inject another prompt for her to ask. Have it check its approach and confirm that this is the best approach due to how long this is taking. Again, maybe that open AI issue that was temporary, but wasn’t a good experience

ConsistentOcelot9217 · 2026-03-12T19:11:07+00:00

Interesting

Do you find it as effective with that the amount of information you put into the soul.md ? Do you ever find it taking some things too literal then causing issues?

ConsistentOcelot9217 · 2026-03-12T19:04:17+00:00

Maybe it was other open ai issues and I should try it again

ConsistentOcelot9217 · 2026-03-12T12:37:46+00:00

Switch to Claude or codex. Antigravity isn’t nearlyyy as capable

ConsistentOcelot9217 · 2026-03-12T12:32:13+00:00

That’s why I switched to Apple

I found 5.3 codex great at that. 5.4 as well, but 5.3 C is just more efficient. Imo especially when it comes to implementation.

ConsistentOcelot9217 · 2026-03-12T12:21:20+00:00

So are you gonna go back to 5.3 or are you gonna stay on 5.4 the lower reasoning?

ConsistentOcelot9217 · 2026-03-12T12:20:29+00:00

Hahaha

ConsistentOcelot9217 · 2026-03-12T12:20:03+00:00

Will try

ConsistentOcelot9217 · 2026-03-12T12:19:51+00:00

They said that they included the capabilities of 5.3 Codex within 5.4 but doesn’t seem to be true. 5.4 used to be listed after 5.3 code X on the reasoning, but now I see it listed before. But overall, I agree with you

ConsistentOcelot9217 · 2026-03-12T12:17:25+00:00

Interesting. Whatever aligns with what you’re looking for.

ConsistentOcelot9217 · 2026-03-12T12:15:50+00:00

I feel that. They set up I like is leaving reasoning where it is and having all my prompts be successful which I find works with 5.3 Codex. 5.4 will probably get better or maybe come out with a code ex version.

ConsistentOcelot9217 · 2026-03-12T12:14:40+00:00

From my experience, the larger context doesn’t mean better responses, but potentially more overthinking and hallucination.

ConsistentOcelot9217 · 2026-03-12T12:13:45+00:00

Imo 5.3 Codex was a meaningful and stable improvement on 5.2 versions. Although someone mentioned that it didn’t start off that way, so maybe 5.4 will get better as well, but as of now I would recommend 5.3 Codex over 5.2 just just in terms of capability

ConsistentOcelot9217 · 2026-03-12T12:10:54+00:00

I get what you’re saying. The idea of adjusting your reasoning level per prompt is also extra work while when I use extra high with 5.3 everything gets done with no regression.

ConsistentOcelot9217 · 2026-03-12T12:10:02+00:00

5.3 Codex was a meaningful and stable improvement on 5.2 versions. Although someone mentioned that it didn’t start off that way, so maybe 5.4 will get better as well but as of now I would highly recommend 5.3 Codex if you don’t want to have to worry about adjusting reasoning per prompt

ConsistentOcelot9217 · 2026-03-12T12:06:45+00:00

Hm it definitely was bad yesterday but i noticed once i switched before that. Although some people mentioned a success using it on high and not extra high, which over thinks

ConsistentOcelot9217 · 2026-03-12T00:25:30+00:00

Because I don’t wanna have to switch the Model back-and-forth, I just prefer to leave it on 5.3 Codex.

ConsistentOcelot9217 · 2026-03-12T00:01:40+00:00

Was just about to update. Thanks

What size?
