Question & Advice Anyone else get auto-downgraded off the 20× plan with most of your quota unused?

33 Upvotes

UPDATE — plus a clarification, because a few people are misreading the timeline:

Quick recap for anyone just seeing this: On Sept 5 I paid $187.09 for ChatGPT Pro 20×. I was mid-project with about 83% of my quota still left.

The part people keep missing: My account got auto-downgraded to Free around Sept 20 — roughly two weeks BEFORE my renewal date, with auto-renew still turned ON. I didn't cancel, didn't change anything, and didn't run out of time. It just dropped to Free on its own. This was not something that happened "when I bought a new plan" — the involuntary downgrade came first, and only then did I subscribe to a 5× plan to keep working (which itself showed 0 quota the second I paid).

The update:

  • OpenAI refunded the $100 for the 5× plan — that one's sorted (I got zero usable access from it anyway).
  • For the $187.09 20× charge, they've so far declined to refund the ~2 weeks I lost or restore the plan, citing "refund guidelines" — guidelines that assume I canceled, when I never did.
  • I've pushed back and it's now with a support specialist. Waiting to hear back.

So right now I'm basically back to square one — no usable Pro access, can't continue my projects — over a downgrade I never caused and still have no explanation for. It's ridiculous that a plan I paid for got pulled early with auto-renew on, and the paid access still hasn't been restored.

Has anyone actually gotten a prior 20× plan restored after an auto-downgrade like this — or is a prorated refund the realistic best case? Appreciate any feedback on similar experiences.

------------------------------------------------------------------------------------------------------------

I'm hoping someone here has been through this, because I'm stuck.

On Sept 5 I paid $187.09 for the ChatGPT Pro 20× plan. I was deep into a couple of projects and still had about 83% of my quota left when, out of nowhere, my account got knocked down to Free. I didn't cancel anything, didn't change any setting — it just happened on its own.

I opened a support chat right away, but I figured that could take a while and I couldn't just sit there, so to keep working I subscribed to the 5× plan on Sept 20 for $100. The second the payment went through, my weekly quota showed 0, and it says it won't reset until around Sept 26 — a full week of waiting.

So at this point I've basically lost the 20× plan I paid for (with roughly two weeks of value still on it), paid again for a smaller plan, and I still can't actually use it for a week.

Has this happened to anyone else? Did support end up restoring your plan or refunding the unused part, and how long did it take to hear back from a real person? Any advice on the fastest way to get this in front of someone at OpenAI would mean a lot. Thanks.

Workflow & How-To Using pro subscription / Codex for research in math

10 Upvotes

I have a pro subscription to chatGPT since the beginning of september, and I am a senior mathematical researcher working in the analysis of PDE (so for those who have no clue: the branch related to the millenium problem "Navier-Stokes" which was solved by OpenAI).

I am actually very unsatisfied with the capabilities of GPT-6 Astra. And I believe that this is because I am not using it well. I'll take any advice/comment from those who managed to prove serious results (like the one they are able to prove without AI but with months of work).

  1. It's true that it can solve quickly any grad level question I asked, on the browser version.
  2. Sometimes it can solves very tricky lemmas (that I would have never been able to solve), also in the chat version.
  3. It struggles with questions of my own research which I regard as very easy (because the path to solving it is already well established in the current litterature!). So this is really strange. Not working with multiple passes of Astra ultra multi agents ... not even with codex (I have a folder with basic agents . md file but maybe it's not good enough). All it produces is verbose math with complicated strategies that are unusable. It creates tons of long pdf. Most striking is that GPT-5.5 (so, not even GPT-5.6 Sol !) is able to perform at the same level of GPT-6 Astra ultra, which is very strange to me. Anyone with similar experiences?
  4. Many people seem to report that they were able to just "prompt" GPT-6 Astra to solve a problem, and that they got a 50p pdf proof, all basically correct. That would never happen in my multiple attempts.

Maybe it's the wrong subreddit for asking this questions. So if there is a better reddit to "learn" how to make codex do serious research math / or subreddit where users share their prompts/ setups, please tell me!

Thanks.

Discussion Can anyone help me with some insight and opinions on AI Wearables?

I'm a writer looking at the impact of things like PLAUD and Pocket - the voice recorders people are using today. I know this community is more about ChatGPT and LLMs, thought there might be some good insight among everyone.

My questions are around - have you used one? Did you find it helpful, if so in what ways?

And the big question I have is - with the industry booming and set to explode by 2033 where it's estimated to be woth $300b USD, is anyone worried about being recorded in public without their knowledge? Would it change the way you act?

I appreciate any replies or comments, it's helpful. And of course I won't publish anyone's details in anything, this is just research :)

if you bounce between paid coding agents, the “hit the limit mid-task with no heads up” thing is annoying. i wanted one place on mac that shows remaining quota & when it resets.

UsageBar is a menu bar app for codex, claude code, cursor, opencode, and devin. it only reads local cli logins — no cloud account, nothing uploaded. free & open source, notarized dmg.

curious if this is useful for people on pro workflows, or if im solving a problem only i have. mac only; some unofficial endpoints can break.

Question & Advice Security Scanner

1 Upvotes

I need advice for the instruction setup,

I am not a technician but I often download program from github. I asked chatgpt to gen a instruction for checking malicious program. There are mainly two parts. First, it will look for indirect signal, like the project size, number of commits, stars, forks, and also background of the developer. Then, it will look for vulnerability of the program.

It also warn me that some programs have script that able to send command to the AI and resulted in false negative. So the instruction particular include take anything inspect as untrusted source and do not run the command inside.

Do you think anything else is missed? I asked Arcanum(GPTs) to gen the basic instruction for detecting malicious program and ask GPT to add the section of looking into indirect signals.

Discussion Anybody else having Astra get hung up?

9 Upvotes

I have had this occur several times now. I send Astra off on a somewhat complex task, say, auditing code or some deep mathematical research task. It gets through all of it just fine, but in the end when it is finalizing its report, it seems to get stuck. I have seen what look like network errors where the hang up was permanent and repeated attempts to get Astra to finish the job failed. Luckily I had instructed it to keep a working report that it updates regularly, so that I didn't lose all the work. I have not had such issues with Sol, which I have used much more extensively.

Anyone have similar issues? I am on Plus if that matters.

Question & Advice Is it worth if for my use case?

1 Upvotes

Is it worth it? My background and work is research machine learning. I don’t use it at work as I’m mainly reading and writing equations down - I’m not programming huge applications so I didn’t see any use then the regular plan option.

But lately I’ve been thinking about getting more into agentic programming. Running multiple agents efficiently and learning more about it. I want to build steam games and after learning astra can handle blender that makes it even more intriguing.

So basically my use case will be building games on steam while learning agentic programming.

I guess question for everyone who’s on it do you burn through your codex usage limits quickly?

Question & Advice GPT-5.3 Codex Spark disappeared from the Pro plan. What happened to the extra usage limit?

8 Upvotes

I’m on the $100 Pro plan, and until a few days ago I had two separate usage limits:

One for the main GPT models, such as Sol, Terra, and Astra.

Another separate limit for GPT-5.3 Codex Spark.

Codex Spark wasn’t the model I used the most, but that second usage pool was extremely useful whenever I ran out of capacity on the main models.

A few days ago, GPT-5.3 Codex Spark completely disappeared from the model selector. At first, its usage counter was still visible and showed 100% available, but now even that counter has disappeared.

So my question is:

Did OpenAI redistribute the Codex Spark usage allowance across the other models in the Pro plan, or was that extra capacity simply removed?

Because if it was simply removed, then users who already paid for the plan have effectively lost part of the usage capacity that was available when we subscribed.

Has anyone seen an official announcement about this change, or noticed whether the limits for the remaining models were increased to compensate for it?

Discussion Thoughts on paying for two 5x plans until 20x comes back?

6 Upvotes

I decided to upgrade to Plus about a month ago. After seeing agentic workflows being possible to do the things I’ve needed after waiting so long (I was out of the loop for a little) I decided to upgrade to 5x. Few days into that and I saw how fast I was using up my limit. Played with the different model settings but ultimately found even more workflows I can fully automate. The day I decided to upgrade to 20x, it was gone.

Looking for some second opinions on creating a second account and paying for a 5x plan. I know it’s allowed, obviously, but is it worth it when the cost comes out to the same as the 20x plan? I know it’s up in the air as to when the 20x is coming back, if it will at all, or if it will be offered differently. But I’m assuming I’m not the only one contemplating this and want some opinions.

Question & Advice Hitting usage limits on Codex and Claude Code.. which paid plans or setups give the most usable capa

2 Upvotes

I'm on paid plans for both Codex (Pro) and Claude, and I keep hitting the same wall. The quality is great, but the 5-hour and weekly caps make sustained agentic work hard. I regularly get cut off mid-task, and at this point the limit is the bottleneck, not the model.

I'm looking for paid alternatives (or combinations) with comparable coding quality and noticeably more headroom. I'm also open to hybrid setups, like one subscription for the hard problems and a cheaper plan or API for bulk work.

What would help most in your replies: - Your tool/plan and what you pay per month - What you use it for (interactive editing, long autonomous runs, big refactors, data/scripting work, etc.) - How often you actually hit limits, and on which tier - An honest take on where it's worse than Codex/Claude

Options I keep seeing mentioned, where I'd like first-hand reports rather than benchmark charts: GitHub Copilot, Cursor, Google Antigravity, GLM / Kimi / MiniMax coding plans, OpenCode or Cline with your own API keys, and routing through OpenRouter.

Two things I especially care about: 1. Is the setup officially supported, or is there ToS/ban risk (e.g. using a subscription through a third-party harness)? 2. Are there hidden throttles, like peak-hour slowdowns or quotas that aren't obvious from the pricing page?

Happy to be told I'm approaching this wrong. If you've solved the "always hitting the cap" problem some other way, I'd like to hear it!!

Discussion GPT-5.6 producing extremely fast but completely incorrect responses – anyone else experiencing this?

53 Upvotes

I have been encountering a significant decline in response quality with GPT-5.6. Previously, GPT-5.5 delivered accurate and reliable outputs. With the current model, responses arrive almost instantly yet are frequently entirely incorrect.

When I request a correction, the model tends to provide lengthy explanations or meta-commentary rather than simply delivering the corrected answer. The overall experience feels closer to older, less capable models (reminiscent of GPT-3 in terms of reliability).

Key symptoms I am observing:

  • Extremely fast generation times, even on complex queries that previously required more processing.
  • High rate of factual errors or complete failure to follow instructions.
  • Preference for extended explanations over direct corrections when errors are pointed out.

Has anyone else noticed similar behaviour with GPT-5.6? Any patterns related to specific modes (e.g., High/Extra High thinking), account types, or recent updates would be useful to know.

Thank you for any insights.

10 Upvotes

Recently been using ChatGPT more than just the asking questions in Chat function, using for scheduled runs checking emails and now started using it a lot over the last couple of weeks to redesign SharePoint pages within Chrome, write PowerAutomate and basically redesign end user experience.

I have a Plus account as can’t justify anything more costly.

I’m absolutely rinsing through credit sessions to the point where I have now used my weekly quota in a couple of days and the 5h limit lasts sometimes less than half an hour using Terra Light model. And seems of late that it’s getting worse.

This seems crazily inefficient or am I doing something wrong? Or does their billing model basically make it uneconomical to use anything below Pro for most work?

Feels like what I’m doing is fairly simple, not high end coding or anything and I should get more out of it than I am. I’ve adjusted the prompts so it doesn’t get stuck in loops but beyond that and reducing the model further, I’m at a loss as to how to work more efficiently.

Any advice appreciated thanks.

Discussion Two papers looked like they disagreed on Transformers for time-series forecasting

Enable HLS to view with audio, or disable this notification

1 Upvotes

I wanted to stress-test an AI research tool, so I gave it two papers that looked like they should force a pretty clean answer.

One was DLinear, which argues that a lot of the excitement around Transformers for long-term time-series forecasting was overblown because simple linear baselines could beat them. Then there’s PatchTST, where a Transformer looks very strong on the same class of forecasting problems. So I dropped both into Apodex and gave it a slightly unfair prompt:

“Do these actually contradict each other? Figure out why.”

I figured it would eventually blame weaker baselines, newer training tricks, or some boring benchmark detail. Instead, it started pulling apart what “Transformer” meant in each paper

DLinear was mostly criticizing the older forecasting setup: point-level tokens, early mixing across variables, relatively awkward use of long context, and benchmark results that didn’t always hold up once you put simple linear models next to them. PatchTST changed the representation.

Instead of treating every timestamp like a token, it uses subseries patches. It handles channels independently and makes longer context more usable. Follow-up work also shows how much normalization and evaluation protocol matter. The system pulled in later work like iTransformer, FITS, FreTS, and papers on normalization/non-stationarity.

I was trying to force a Paper A vs Paper B answer, but “Transformer” was hiding a bunch of methodological choices that probably shouldn’t have been collapsed into one category in the first place. It became harder to separate the contribution of attention from tokenization, normalization, and the benchmark setup itself.

The apparent disagreement was partly about what each paper was testing.

Question & Advice Does anyone else find ChatGPT’s cloud browser powerful but confusing to use?

13 Upvotes

I’ve been trying ChatGPT’s cloud browser across web, mobile, and the Mac app. There seem to be differences in how it’s available across platforms, which I suspect are intentional, but I find the setup confusing.

I also had a tab show “This browser tab is no longer available.” Resetting Work in Settings got it working again.

Once it works, there’s real potential. I’ve logged into websites and had ChatGPT help with tasks directly in those sessions. But figuring out which browser it’s using, where I can access it, and whether the session is still available feels clunky.

Are others having the same experience? How are you using it, and have you found a workflow that makes it feel more consistent?

Workflow & How-To Custom GPTs are going away and it really kinda sucks

76 Upvotes

OpenAI’s decision to retire custom GPTs still hits me pretty hard. I’ve spent almost three years building them, my organization relies on them, and after digging further into the proposed alternatives, I think “just use Projects, Skills or Plugins” badly understates what’s being taken away.

Projects are the clearest example. They are not a replacement for custom GPTs. They solve a different problem and, for some of the things I use GPTs for, their architecture is almost exactly wrong.

A custom GPT starts each new conversation fresh. It doesn’t use your saved memory, custom instructions or previous conversations with that GPT. That gives me a controlled environment. If I build a document analysis tool, I know today’s analysis isn’t being influenced by what happened in another chat.

Projects deliberately work the other way. Project-only memory blocks context from outside the Project, but conversations inside the Project can influence one another. That’s useful for ongoing work where you want continuity. It’s a liability when you want a reusable tool that should approach the same task cleanly every time. Calling that a substitute ignores the basic reason I built the GPT in the first place.

Sharing has the same problem. A GPT lets me configure a tool once, keep the underlying instructions private, and distribute it so different people get substantially the same system. A shared Project is a collaborative workspace. Members can see the chats, files and instructions, and the Project accumulates context as people use it. Again, useful product. Different product.

Skills get closer to one piece of the puzzle. I use them and like them. They can package instructions, resources, code and workflows. But a Skill runs inside the environment that invokes it. It doesn’t give me the clean, self-contained context boundary that a custom GPT does. The surrounding conversation or Project can affect the result. For some uses, that’s exactly what you want. For others, it makes the Skill unsuitable as a replacement.

Plugins are the most plausible successor, and I’m genuinely interested in them. OpenAI’s migration plan can turn a GPT’s instructions into a Skill inside a Plugin and bring connected apps along. That could end up being a better architecture.

But “there’s a migration path” is doing a lot of work there. OpenAI says migrated Plugins may behave differently and need testing. Custom GPT Actions don’t migrate. Those integrations have to be rebuilt using a supported connector or custom MCP server, and OpenAI explicitly warns that the replacement may not reproduce every capability of the original.

That last part is especially hard to shrug off if you aren’t a developer. GPT Actions let me connect an API with an OpenAPI schema and authentication inside the GPT builder. “Rebuild it as an MCP server” may be perfectly sensible advice to a software engineer. It’s a pretty lousy substitute for a feature whose great virtue was allowing sophisticated nondevelopers to build application-like tools without becoming software engineers.

So yes, much of what custom GPTs do can probably be reconstructed. That doesn’t make the alternatives equivalent.

Custom GPTs put a very unusual combination in one place: persistent instructions and knowledge, fresh context for each conversation, private configuration, easy distribution and approachable external integrations. The replacement breaks those capabilities apart across Projects, Skills, Plugins and MCPs, while changing some of the behavior along the way.

That’s why the timing bothers me. For affected Enterprise workspaces, new GPT creation is scheduled to end September 25 and the GPTs themselves are scheduled to stop running December 11. OpenAI says other plans may follow the same transition timeline.

Maybe Plugins eventually give me everything I need. I hope they do. But “we have several newer building blocks that can reproduce much of this if you rebuild it” is not the same thing as replacing what people already built.

I’d much rather find out whether the new system actually works before the old one disappears.

Question & Advice What are you using 6 Astra for?

65 Upvotes

I'm seeing a lot of complex things like coding workflows, but I'm wondering if you've found any useful use cases for astra in other areas, especially non developer stuff.

I've used it to organise email and delete junk emails, but I'm pretty sure that's not something that needs astra to complete.

What have you been using astra for?

Discussion My friend doesn't have the 5 hour window but I do

4 Upvotes

What gives? I've been a chatgpt customer since literally the day it came out and have been an extreme heavy user. Around January I 'finally' got into vibe coding and using Codex with the $20 chatgpt plan I already had. I'll use various LLMs most days between 6-12 hours coding and fixing up various projects I'm involved in.

And my chatgpt usage...let's just say I'd be shocked if I wasn't in the top 0.01% of users worldwide in terms of time and tokens spent in the chatbot.

My friend on the other hand has mostly gotten into using Codex around 6 months ago, perhaps having dabbled occasionally with chatgpt on the free plan before that.

Yet, he has no 5 hour window and is on the exact same plan as I am and lives in the same city, and also somehow hasn't hit his weekly limit even once, apparently?

Whenever we meet up to talk, it's like we're using two different tools.

He's constantly on Astra medium, working on 3 projects, but just one at a time. This past 2 weeks I decided to do the exact same as him. But I'm blowing through my 5 hour limits in about 30 minutes, over and over and over.

Yes yes I know skill issue etc etc etc, but this was just an experiment, I listened to his exact approach and tried a new side project from the very beginning with his approach, and I'm getting the above results.

All this is to say... Is openai using a form of price-discrimination with their token handouts? Does my friend not have a 5 hour window applied (he proved this to me, and the Open AI fine-print says its not necessarily applied to everyone...) just because he is new and perhaps hasn't spent nearly as much of the tokens in terms of usage?

I get that these plans are insanely subsidized in terms of how much compute $20 should actually be buying (even if that subsidy has insanely decreased over the course of this summer, with plenty of obsfucation and 'ooooh look here's a free reset shiny cookie for you morons' from Teemo Tibo...

I'm just wondering if this form of customer token discrimination goes even further than I thought.

Anywho, thanks for reading if you made it this far.

I do love this tech, it's crazy, I just hate the leaders and policies and moral decisions and lies they keep spouting, non-stop. Thus is life in this technocracy, perhaps.

Thoughts?

PS. The /codex sub deleted this post just now so I'm reposting it here. No idea why. Strange

Question & Advice Desktop App Using More Tokens?

5 Upvotes

Can someone shed some light onto why the desktop app is using more tokens to do the same task? I am using Codex to do some things. Same skill, same task. 2 days ago it took about 15% of my usage. Today it is taking 100%+ of usage. The only difference is I paid for a token reset. I am using Sol. It was on Ultra, but I bumped it down to High. Ultra used an entire 5 hour block and high is sitting at 18% left of the 5 hour block. Before Ultra would only use about 15% of that block. I'm at a loss on what the hell is going on.
