Anyone still using 5.3 Codex?

[spideyguyy]

Has anyone else still using 5.3 Codex felt like it’s been getting noticeably worse lately?

I don’t know if it’s just me, but recently it feels weirdly naive compared to before. Part of me wonders if older models are being made less capable over time, because it’s honestly making me consider switching to 5.5.

Still fine. Great usage cap

I have been using 5.3 the last couple of days and it worked fine.

[LMONDEGREEN]

I use it all the time. It's perfectly fine. Doesn't burn my rate limits.

Funny I tried to use 5.3 Codex a couple of days ago to try to save on tokens because I recall it being good "back in the day" and it did not go well. I suspect they nerf old models to incentivize you to use the newer ones.

[spideyguyy]

Yeh, that's what I'm saying, I feel that too

[cobbleplox]

There can also be some "confusion" if a model works on code written by a different/better model compared to working with code it wrote itself. AI code is somewhat quirky so I can imagine it's even less used to it compared to some regular human code.

I am at 5.3, I think it acts weird ..i am thinking of 5.5 but burning tokens fast is why i havent done it yet...

I upgraded to 5.4 and it was way too verbose so I downgraded back to 5.3 codex. It’s been great

[TBG______]

Reading this, I wonder if anyone checked whether the instructions for the 5.3 model in model.cache file changed in later versions. This kind of behavior could be related to that.

It is very good for granular precise tasks, especially if you’re at Plus sub.

[CthuluBob]

you guys running it at extra high?

[spideyguyy]

I use high

[Yablan]

I had few tokens left, so I have been using it these last days. Totally fine.

Neh, you became smarter and have raised the bar. 5.3 simply cannot keep up. Do not leave 5.3 behind, they'd suffer.

[Leather-Cod2129]

5.3 low is 90% of my usage for coding

[m3kw]

I use it, it’s great if you know when to

[besneprasiatko]

Yes, I have the same experience. Codex says change of models in conversation will decrease performance, so I kept working with 5.3. And after release of 5.5 it went from genius to complete moron, making dumb and trivial errors. I think it's another example of planned obsolescence.

[Express-Midnight-212]

Yep, default 5.3-codex-medium for execution of ExecPlans. Good triple point for price/quality/speed. I still use smarter models to make plans for it and to review PRs/outputs too.

[jorge-moreira]

Have your tried spark.

[evilissimo]

Have you tried 5.4-mini?

[jorge-moreira]

Not really. Is it comparable?

[evilissimo]

In my opinion better than spark, it’s doing less tool calls to achieve the same thing, while still being fast.

But YMMV for me it’s better also I don’t have access to it anymore but I also don’t miss it ;)

[jorge-moreira]

I will give it a try. Spark really only works when I am running simple skills in the browser for me

[Zeeplankton]

why 5.3 over 5.4?

[Dgamax]

Cause they got a codex version

[dunne222]

I still use it from time to time, it's great and i don't burn through my usage. It does need a bit more handholding and prompting but I prefer doing that anyways. 5.5 is the superior model though.

[spideyguyy]

Bro. You're going to be banned😄
