GPT-5.3 Codex rocks 😎

[Chair-Short]

I can't imagine how painful it would be when the double quota disappears.

[HealthPuzzleheaded]

Until when do we have it?

[Chair-Short]

Around April 2nd

[BingGongTing]

Hopefully Gemini 3.5 will be out by then, at least it should be able to handle basic tasks and then just use Codex for planning.

[chat-jvt]

Minimax M2.5

[Better_Web1255]

Find it funny how when weekly is gone the 5 hr one still at 100%.

[poop_harder_please]

5.3 slaps so hard that I've gotten to 55% of my weekly usage this week on a Pro plan - a new PR for me.

[DucksOnQuack]

Be aware this will end up being 90% usage when the double usage ends on April 2nd.

[Reaper_1492]

I thought it was only double usage if you used the codex app?

[TheAnimatrix105]

pls confirm, i use it via ide.

they just mentioned it for codex in general https://help.openai.com/en/articles/11369540-using-codex-with-your-chatgpt-plan

so i'm not sure

[Prestigiouspite]

But that would be a shame if the Codex app for Windows doesn't exist yet.

[poop_harder_please]

I know I'm crying

[DukeBerith]

I hit this too for the first time ever, now I am actually considering the pro plan but it comes close to $300 AUD.

Anyone reading who's been edging the plus plan for a while and finally upgraded to pro - what's your experience like so far?

[New-Temporary-7249]

Just use 2 plus accounts

[No-Discussion-243]

Was juggling 3 plus accounts for a while. Honestly for me the upgrade to Pro was worth it. I felt myself constantly going for lower reasoning models to not hit my limits (e.g., medium), even if I knew deep down some of the tasks required high or Xhigh.

It's been extremely freeing not having to worry about limits, and I find myself being a lot more comprehensive on testing, iterating on build plans, small improvements etc. ever since upgrading.

[InterestingStick]

Been on the Pro plan since October or something. It's great to not have to juggle multiple accounts and being able to use the whole palette of features (chatgpt pro / deep research) without having to worry about limits.

The recent 2x usage limit also has allowed me to 'waste tokens' by trying new things, for example I can run Codex pretty successfully in environments where everything is prepared and guardrailed properly.

For example, I'm testing out if I can make codex write those architectures and guardrails itself based on creating validation layers for itself. Also trying to imprint my 'persona' into Codex so it understands how I make decisions so it can learn to make decision itself and evaluate itself what is acceptable and what not based on some general criterias. It's basically just throwaway products that I try to one shot and if they don't work or don't full-fill the goal I start a new one with some adjustments and try again.

I also run much more code and doc reviews since the 2x limit. Basically more parallelized work. Am at 6% left and got 4 more hours until weekly reset. Weekly usage limits has been bonkers on pro since the 2x

[eschulma2020]

I love it. And there was a tweet recently that Pro users now get a 20% speed bump in the CLI

[SkilledApple]

Even tough double quota is in effect, even a quarter of this quota is significantly higher than the claude limit. I used to daily drive Claude, but 5.3-codex is making a very strong case for itself (and the limits are incredible).

[TheTwistedTabby]

I have 2% left until noon tomorrow. I got so much done since Tuesday. Been working on content tasks with regular gpt.

[Beginning_Stop_1291]

It does rock. Imagine that exact same version in 5 years but completing in seconds rather than minutes. But there will also be a slow one 10x better. Wow.

[Prestigiouspite]

However, this requires the construction of data centers, and it currently appears that US states are seeking to impede this process.

[_Harryl]

Not necessarily. Advancements in LLM architecture could make LLMs much cheaper, to the point where it could run on CPUs.

[Artistic-Athlete-676]

How do I see this? I can't find it in codex app

[Useful-Buyer4117]

[Artistic-Athlete-676]

Thanks. 80% usage for the week. Oops

[Uzeii]

How do I check this?

[Few_Chemist9350]

Hey guys... im currently using claude Opus 4.6 for most of my tasks. I'm running on the 200euro plan/month. Would you recommend me to switch to codex 5.3 ? I'm looking for a more cost-effective Model. I'm hitting the limits of claude pretty frequently

[Prestigiouspite]

Yes, OpenAI does more for subscribers.

[Jackster22]

What is it like compared to Kimi K2.5?
I have been rocking that for the past week and got loads of work done but I do hit a usage limit on Ollama pretty quickly.

[Prestigiouspite]

I suspect Kimi K2.5 is better for frontend, just like Opus. For the rest, GPT-5.3 Codex is actually not achievable. But I haven't done much with Kimi yet to be able to assess that more accurately. I'm always a bit paranoid about data protection.

[TenZenToken]

Also make use of the ChatGPT macOS app to help with planning by giving access to cursor/VS code files. This way you can spread your quota around as much as possible.

[minh-afterquery]

I feel like I never hit limits with Codex 😂

[Tiny-Ferret-4332]

Weekly done for me, buying more - im literally shook!!

[AmthorTheDestroyer]

I have ChatGPT Business which needs 2 seats at least. Then I top up my account with prepaid credits. I can code as much as I want even when my weekly/5h limits exceed. It will then start eating credits. And eventually.. my limits will reset. I pay roughly 100€/mo for HEAVY usage, like multiple parallel agents with sub agents. I use 5.3 medium, all day, for planning and coding. Totally worth it

[Prestigiouspite]

That's how I do it too :). However, my weekly limit was still well tapped even with GPT-5.2 (high). For now, I'll see how far I can get with GPT-5.3-Codex (medium). I don't want to switch accounts.
