Day 25/ We are doubling all usage limits for all Pro 100/200/500 tiers and Business Premium, effective today. We heard your kind feedback and won’t be reducing usage limits for Pro 200, so your Work and Codex usage will stay the same. We’re also going to continue offering extended limits for dots for now, and usage of your dot will still continue to be separate from your default usage. And we'll of course also keep shipping better models and other efficiency improvements that increase your effective usage over time.

I have nothing but respect for the ChatGPT/Codex team, I know you're all working very hard to give us better intelligence/dollar, this is just my perspective on the upcoming usage changes As a longtime $200 Pro user, cutting our usage in half feels somewhat out of left field in that we're the only plan not benefiting from the recent gains in cost efficiency, and in some ways we're actually getting less usage than we have in the past The newer Luna, Terra, and Sol models cost ~half as much as their 5.6 counterparts. This is great news for Plus and $100 Pro users, since they'll get ~twice as much usage with those models as they did with 5.6, and their Astra usage stays the same Unfortunately for $200 Pro, the lower cost is offset by halving the allowance, so we get roughly the same usage as we had with 5.6 models, and half as much Astra and image generation Like let’s say hypothetically that 6.1 Astra costs half as much as 6 Astra. $100 Pro would get twice the usage relative to 6 Astra now, while $200 Pro would be exactly where we are right now, meanwhile we're struggling with Astra usage already If you're familiar with Claude subs, this change is functionally similar to how Claude Max plans cap Fable at 50% of weekly usage. It seems OpenAI is going for a similar effect with Astra (by cutting limits), but only for the $200 Pro tier which is frustrating I know a ton of $200 Pro users who already feel like they're burning through their usage and are reliant on resets, and this is before any cuts. Some even told me they plan to cancel their OpenAI subscriptions in favor of Claude bc they feel they'll get better value for their money without the sporadic resets We pay a substantial premium month after month because we believe in the product and want to support improving it. As models become cheaper and more efficient, the customers who've supported OpenAI (at what was its highest price point) are the only ones seeing their access shrink rather than grow I'm not saying we need to be 'rewarded for our loyalty' or anything like that, but it's frustrating to feel like we're being penalized for it. I really hope OpenAI will consider increasing the $200 tier to 15x instead of 10x (or simply increasing plus usage). It would make the $200 plan feel more worthwhile for current subscribers, while giving us a better reason to move up through the tiers as well

I did say we'd be releasing our models periodically...introducing Gemini 4 Carbon, our next frontier model. Following Argon's release just two weeks ago, Carbon shows the pace at which we’re pushing the frontier, it ranks #1 on the recently updated v5.0 of @ArtificialAnlys Intelligence Index at 59. It also leads across key cybersecurity evaluations scoring 88.2% on SEC-bench Pro for finding vulnerabilities, 54.8% on ExploitGym for exploitation, and 71.0% on CWE-bench for patching. We’re seeing significant improvements in long-horizon tasks even compared to Argon, and we’ve strengthened frontier safeguards. As we did with Argon, we’re going to roll it out gradually + responsibly. Some trusted cyber defenders will get access starting this week. We'll be expanding it to more partners through our Fairwind Program, ahead of wider availability soon, so hang tight!

OpenAI reducing limits on October 30th will be a disaster for the company. I am SHOCKED at how bad the limits are already, I'm at 12% left with 5days left until the plan renews. This will cause a mass exodus from Codex. If they do follow through on this plan, once my resets are done, and my one tie allotment of 62500 credits are gone, i'll be shifting my Pro plan to Claude Max.

So deserved, Harry. Congratulations. ❤️

Another British Fumble! £2bn AI data centre in Essex. 23,000 Nvidia chips, planning permission sorted, Microsoft signed up as the anchor tenant Microsoft has reportedly now walked. Because the grid told them they can't have the power until 2033/34 The government literally named this site in its own AI action plan. They talk about AI growth zones every other week. And we can't get 90MW to a field in Essex for 8 years Same story as the reservoirs. We don't build the boring stuff, so the exciting stuff can't happen here

Jensen Huang on why the UK is in a great position in AI: “The UK is in a Goldilocks moment. You have every aspect necessary to take advantage of this new Industrial Revolution. You just have to activate it” He went on say how crucial fixing energy prices are in the UK if we want to take advantage of this moment.
