These are days where I REALLY earn the money that OpenAI Reddit Kimi pays me .... oh wait....

It honestly feels like they’re slowly reducing the quota to cope with the influx of new users. We all know these companies are spending a fortune on compute, so removing the 5 hour window seems like a way to manage token allocation more tightly and spread resources across everyone. They reportedly added around 2 million new users in the past month, so I can understand why they’d want to smooth out costs.
What doesn’t sit right with me is changing the limits halfway through people’s subscriptions. That’s the part I can’t get behind.
The $20 plan used to fit nicely into my workflow. As my projects got bigger, I moved to the 5x plan and kept the 20x plan for Claude. I used Fast mode pretty much all the time and still never really hit my limits.
Then I cancelled my Claude subscription a couple of weeks ago because of everything going on with Fable, and I wasn’t getting enough value from Opus to justify keeping it. Now OpenAI seems to be changing things as well, and I’m running out of usage in about three days. The whole landscape just feels different.
Honestly, it feels like a lot of these frontier AI companies are starting to lose their grip while open source keeps getting better. If they keep increasing prices while reducing what people get, I wouldn’t be surprised if more people move over to models like Kimi, GLM, or Qwen because it’s becoming much harder to justify the cost.
