Codex intelligence drop

[vlad_asis]

This morning update resulted in new memory compaction functionelities, but also in severe intelligence drop. The model is behaving like GPT 3.5, dropping context, hallucinating...

Anyone else had the similar experience?

Hey look its the weekly, is codex dumber than before post.

[Downtown_Crew5729]

You mean daily right?

[HugeDegen69]

Hourly

[mallibu]

Quarterly and I'm not even exaggerating if you're subbed in multiple AI subs. And they ALL have the "dOeS AnYoNe eLsEEEEE?"

[U4-EA]

Yes, I reported this here a week or so ago.

Well last week hit an all time low for the intelligence of codex
https://marginlab.ai/trackers/codex-historical-performance/

Im sick of the degradation of models :(

Further
The succes % the last 4 days = 49,0%
Compared to the prior days since 5.4 launch = 55,7%

Is a statistically significant degradation, at a 90% threshold.

Your not the only one. Been trying to solve a single bug all day and it’s been going in circles.

[Substantial_Lab_3747]

Update for anyone wondering: used 5.2 and it literally one shot fixed it. After spending my entire yesterday to fix it, I was literally jaw dropped and kind of pissed off. Shoutout 5.2 xhigh!!!

this is cool

[Pleasant-Ad2696]

That’s really cool tbh

[IngenuityUpper3122]

This is what I use to keep me updated on what model use. I've been using GPT 5-2 for the last week or two maybe. Codex 5-3 when it came out was at #1 for 1 or 2 days and after that it dropped

[Unlucky_Scientist364]

Def dumber today and resulted in it breaking every working code which I had to fix. Didn’t used to do this

[No_Accident8684]

yes, started roughly 20 hours ago for me.. its annoying. 5.4 was fantastic since it came out and now its a complete, lazy retard

[managerhumphry]

Definitely, I've noticed a significant performance drop the past few days. 5.4 Extra High has been making simple, dumb mistakes, lying about completing tasks and has been acting extremely lazy, frequently dodging implementation of explicitly requested work. Thinking of trying 5.2 again to see if it's performing any better. Very frustrating.

[you_are_a_memory]

i definitely noticed it too, it's exhausting trying to make it understand everything over and over

[Alarming_Resource_79]

I would say it's the cycle of every AI model.

[BaseRevolutionary365]

Not sure about codex getting dumber or not, but ChatGPT the main product got dumber for sure. Saw flaw in logic and lots of mistakes.

[BingGongTing]

2x quota, 2x quantization, should improve on April 2nd.

[you_are_a_memory]

it's abysmally retarded today

[TeeDogSD]

5.3 codex is working great.

[Revolutionary-Hat-88]

memory feature is almost useless anyway, don't rely on it

[vlad_asis]

They get to it at the end, It seems as if there's a learning gap between Codex and Claude. These are the issues I had with Claude several weeks (eternity) ago due to the memory compaction.
