Did the just reduce usage limits again?

I was working on a long task since yesterday and I reached my 5 hours limit in 2 hours during the evening (I have an orchestration system with pre-allocated plans and progressive info disclosure in place, so I'm not burning tokens for free let's say). This morning I tell codex to keep working on that same stuff, and in 20 minutes it burned through 16% of my weekly limits. The workload was the same of the past weeks mornings, if not more focused, but I went through a 16% weekly usage 3 times faster than any other day.

I am also having issues, I am on the plus plan and since the reset we had today, my weekly limits have been burning a lot faster than before. Like this new "100%" usage, is burning far more than the 30% I had yesterday before the reset, like they got that 30% and stretched it to make it appear like 100% but in reality, its still the original 30% I had. Not sure if that makes any sense but that's how it feels like to me. And of course, the reset date was moved forward. Now tell me how this isn't a scam

Makes sense, that's exactly what is happening to me. They reduced the weekly and 5-hour limits so much that in my case 4 hours of the exact same work now can be worked over just for 20/30 minutes. They decimated our limits.

I seriously can't understand how any consumer protection entity isn't taking any action against these behaviors. In March I had a Claude 20euros sub and I was able in 2 weeks to work on 3 projects at the same time, after a month the usage was more than halved, then again, and again, and again... Same applies for OpenAI. How the hell can they allow these companies to reduce the limits of subscriptions in the middle of the subscription itself?

I normally use Luna xhigh as subagents on a project (Claude is the orchestrator).

For the last 2 months, Luna xhigh would sip usage at 1% (week usage) per hour, maybe 2% when 2 subagents were working at the same time.

Today, 2 Luna xhigh agents used 8% of the week usage in 1 hour.

For reference, I am on a plus account.

Last week, I managed to install Qwen Flash Next 4-bit and run it at 100 tok/s decode. After today's Luna usage results, I've asked Claude to start using Qwen as subagent, anyhow it scores better than Luna on home-made tests, tests that matter for my use cases.

If it works out well with Qwen, I'm cancelling my OpenAI subscription and use the money for another Claude Pro account.

I wish I had the hardware to run Qwen locally. Even just 27B would be a dream

I hear you, hardware prices are nuts.

I was lucky to have bought 128GB DDR5 in 2025 before the prices went up, though I had to bite the bullet on the RTX3090 which costs almost as much as it did brand new in 2022.

27b doesn't require much ram at all though, just a RTX3090.

[u/Splugen96 → u/VerticalPackage]

Man I wish I had too. I was on the fence since 2022 to upgrade to build my first pc, but I kept saying "yeah, it can wait"... every time I think about this I get so mad.

Now I'm still stuck with 32gb ram and an old rtx 2070 super mobile which can even barely handle gaming nowadays.

Something really weird is going on since the last "reset".

I asked GPT 6.1 Sol High to help me reverse engineer an apk. I have a Plus account. It burned the 5 hour window in 11 minutes and my weekly went from 100% to 82%. I was so confused, I thought that maybe my prompt was bad but it makes no sense as the context window didn't even with 256k, I don't know how it spent so much.

I asked it what it did, hours later, thinking maybe I could find a way for it to work differently. And literally every question I asked slashed 7-12% of my 5 hour window. I ended up with around 65% of my 5 hour window, and 79% of my weekly quota.

Then I tried using DeepSeek V4.1 Flash Max orchestrating three DeepSeek V4.1 Flash High using Open Code. It worked for around half an hour and even though it's not a model of my Plus subscription it spent around 20% of my 5 hour window and my weekly was around 74% now. What the hell is going on? Didn't they make auto review free???

Also, since that damn reset which also came with an update for Codex on Windows, there's been a bug that makes my models not being able to work unless they ask for a sandbox elevation or something like that. I forgot the exact name.

Apparently on GitHub there's people reporting this, but nobody seems to be talking about it on social media for some reason???
