dot is my favorite openai product so far! it is amazing to me that each day it feels noticably better as it learns more of my workflow and style. having it do the stuff i don't like doing--and usually just builds up as a gravity well of dread--has me very happy.

Stop what you’re doing and build a plugin extension for ChatGPT. We’ve grown over 2000% since the announcement!

this guy really loves talking about buttholes

I got to try ChatGPT’s new dots personal assistant ahead of time as part of their Dev Early Access Community testing. TL;DR: It saved my day today. Longer version: I had an early train to London today. I woke up to find it had been cancelled (yay, UK trains!), and I had to get a later train – I would end up being late for my event, and the later train would likely be swamped with people. There was an earlier train available, but it was in 20 minutes; there was no way I could get there in time. It turns out that my dot had spotted the problem, read the cancellation email to see my ticket was valid on earlier trains, then looked up the live tracking for the earlier train and found that it was running late – it hadn’t even left its starting station yet. It did this with zero input from me; not even an initial request, just fully autonomously. So, I was able to leave more or less as normal, head to the train station, and catch the earlier train just fine. Train: Caught. Day: Saved. Me: Impressed.

Having the library is a competitive advantage

following up after astra launch week and the navier-stokes announcement i wanted to share a little bit about how we think about and build for the over 1 billion people who use chatgpt every week, most of whom use it for free. we’re on a mission to distribute the benefits of agi, and i think this is the most impactful way to do that: giving people as much access as we can safely and feasibly distribute. we want to scale the utility that everyone gets from ai. over the past 6 months, we've been working to bring the greatest possible capabilities to the broadest possible set of users, including both free and paying users. of course there are some practical limitations and we can’t ship the largest models to everyone, but since march (gpt-5.3 instant), we’ve improved the default chatgpt experience meaningfully: - responses with a major factual error are down 65%, and they are down 72% in high stakes categories like finance - gpt-5.6 sol at instant and gpt-5.6 luna at medium are smarter than o3 at high reasoning effort, our frontier reasoning model from 17 months ago, while being considerably faster, 30%+ faster time to last token (evaluated via GPQA diamond) - chatgpt is far more usable and enjoyable while bringing extreme sycophancy down 80% and overall sycophancy down 83% - on our high-stakes medical eval, chatgpt produced 83% fewer answers flagged for hallucinations, resulting in hundreds of millions of better health conversations per month - we're seeing people find more ways to use chatgpt. for a recently joined cohort, we saw the number of use cases pursued at least three times weekly go up 20-30% not only have we improved the default chatgpt experience dramatically, we’ve also expanded access significantly for all. free users now: - have access to unlimited text chats - can use higher reasoning effort - now have access to automations, letting them schedule tasks to happen later - have access to better memory through dreaming. this allows chat to personalize much more effectively we’re always looking for ways to expand access to the billion+ people who use our product weekly. this is the master plan: bring the default experience as close to the capability frontier as possible, expand access to everyone, making intelligence maximally abundant, and make our product much more usable. this last point, usability, is something we’ve been focusing on as we bring personal agi to everyone. the current top of the line capabilities are staggering, but only the savviest users and insiders know how to use them. our vision is of a progressive, model assisted, onboarding to agi. chatgpt will guide people from all walks of life to the highest utility applications of ai for them. this really is the only way – we think technology that is hard to learn ultimately fails to reach a broad audience. your personal agi will just understand your goals, and automatically use the right set of features and capabilities to get things done for you lots more to come soon. onwards to scaling utility for all

Say no to slop

This has been happening every week since I joined OpenAI.

ChatGPT memory is currently incredible. It has pretty much perfect recall whenever I ask. @ChatGPT @OpenAI

An internal version of our next major model produced 10 new results on long-standing open problems in mathematics and theoretical computer science, using roughly $2,000 worth of tokens at GPT-5.6 Sol API rates.

Turns out GPT-5.6 Sol is actually SoTA on ARC-AGI-3. Just took two setting changes. You just have to allow it to reason and work over multiple context windows with the help of our canonical compaction implementation. openai.com/index/how-two-set…

10M! New day, new usage reset for paid users of Codex and ChatGPT Work. Lands in the next hour. Enjoy.
