Day 3 of building WhatsFit in public 🚀 Need to pick an AI model for our fitness companion. For WhatsFit, I need something: → cheap enough to scale → intelligent enough to be a good coach → most importantly, talks naturally like a human I think I'll be picking one of the GPT mini models. It should do the job for me. Model nerds, give me your suggestions 👀 artificialanalysis.ai

@ThePrimeagen 😭

Just got done listening to Cats in the cradle Now I am crying I could make an incredible linked in post right now

@thsottiaux Gpt the goat

You know it's a good model when you grow more in 1 day than last two weeks combined. Install the desktop app from chatgpt.com/download/ and give it a go!

Type the letter "C" into your browser's address bar. What's the first website that autofills? Mine is always ChatGPT.

What do you think of the Whatsfit logo? Whatsfit is a WhatsApp-based fitness companion that’ll keep you consistent. New updates coming soon! 💪

@svpino AI is imagining a lot in these days,

The inevitable future of AI-generated video is interactive livestream-style experiences. More "live interactivity" rather than "static video". This reminds me of the ad screens in Minority Report. The ads reacted and catered to specific pedestrians as they passed by. It's way early for this, but here is a cool demo that shows the potential. You'll find the link in the quoted tweet below

@garrytan Lets go 🔥

We are all just getting started

This is bigger than Intel. The Trump administration reportedly pushed Apple and Nvidia toward Intel's foundry business to strengthen domestic chip manufacturing. The AI chip race is no longer just about who builds the best chips, it's also about who governments want building them. wsj.com/tech/the-white…

@marclou Lets fry that one 🥰

I want worms in my vegetables. That’s how I know they weren’t drowned in pesticides.

@gdb I will be switching to gpt this month

Sol for complex reasoning and data analysis:

@OpenAI Benchmarks are getting crowded

GPT-5.6 is a major step forward for health intelligence. Across the lineup, we’re delivering stronger performance at lower cost: GPT-5.6 Luna outperforms GPT-5.5 at its highest reasoning setting while costing 25x less. Together, these advances raise quality while making advanced models accessible to more people globally.

@elonmusk Perplexity still alive 😌

Try Grok 4.5 in Perplexity

@ThePrimeagen doctor strange: we are in the mirror dimension now.

am i the only one that thinks "to the top right" always means good has been so thoroughly and poorly executed when it comes to model cost / task? please tell me i am crazy because I hate this trend

@ThePrimeagen i am gonna create a chart "bottom left" is the top

@ThePrimeagen where is 5.6 medium 😅

the new life of benchmaxxers you have to read charts like this, consult your shaman, ask begin for a suno song, and figure out what model is right for you... Do i need to carry a protractor with me from here on out?

@ThePrimeagen Cost -> Fable-5 first price 🥇 Gemini is lonely though

@thsottiaux Thank you beautiful man!!!!

Hello beautiful people! We have reset usage limits across Codex and ChatGPT Work. And another one will come later in the day. Rejoice. Now that I have your attention, a quick update on ChatGPT Work, Codex and all the updates we shared yesterday. We’ve spent the last 24 hours reading feedback, looking at usage patterns, and talking with many of you. The short version is that there is a *lot* of excitement for GPT 5.6 Sol, ChatGPT Work on mobile & web, but also that we didn't get everything quite right. - We made it too easy to use the highest-compute settings without making the impact on usage limits sufficiently clear. - We reorganized the desktop app in one bold move, making familiar things like chats and projects harder to find. - Our launch framing was focused on ChatGPT Work and to some of our Codex fans it made it feel like Codex was going away over time. Absolutely not our intention, we love Codex and it is here to stay. - And we introduced regressions for some existing multi-agent workflows, alongside a collection of rough edges in plugins and other parts of the experience. We’re landing a first set of improvements today. We’re resetting usage twice so people can keep experimenting, changing defaults and the model picker so they don’t push people toward unnecessarily expensive settings, fixing several plugin submission issues, improving how we represent Codex in the product, and cleaning up some of the most immediate desktop problems. A larger set of improvements will land next week. We’re bringing chats and projects back into the sidebar in a more familiar and customizable way, making usage and reset timing much more visible, clarifying when to use ChatGPT Work and when to use Codex, and addressing the many other smaller pieces of great feedback we've had. The ambition behind this launch hasn’t changed. We think bringing ChatGPT and Codex together into a workspace where people and agents can collaborate is a very important step forward. But an ambitious direction doesn’t excuse avoidable confusion or regressions in the first version. Please keep the feedback coming. We’re moving quickly, and you should see the experience already get better with a few updates today; and substantially better again next week.

@levelsio Cool another startup idea

So I am trying to hit a 500 calorie deficit every day + hit my protein goal of about 150g (2g per kg bodyweight), and I used Claude chat for that, but after a week it starts losing track so I asked it to export its data as CSV and copy pasted that into Claude Code on the VPS And asked it to build a little calorie tracker called 🥩Caltrack with a Telegram bot too, so I can log whatever I eat or drink in there either via Telegram or if I want more granular via Termius SSH on the VPS I like to do this mix of Claude Code and a dashboard/chatbot because you can ask more deep questions to it like "how am I doing", "what to improve" etc. it's just much smarter and "able" on the server than the Claude chat app by itself Anyway my goal is to get @marclou levels of body fat, which is LOW, right now we're strong and lean but we can be leaner, let's try 😊😊😊 80% of body fat is decided by what you eat, only 20% what you exercise, some say even 90% vs 10%, I agree, I eat very clean but I was mostly staying on maintenance Silly calorie dense food like yogurt with low protein, taste nice but it gets you away from your calorie deficit fast, and to figure that out you kinda really gotta track things Other people suggest crash diets like eat only sardines, we know from studies though that crash diets are temporary, you just gain it back Claude says the ideal is just 500 calories deficit per day and hit your 2g/kg protein goal and you maintain muscle and reduce body fat! So I'm doing that And this app I made helps a lot!!! Thank you for your attention to this matter!!!

@tunguz Fable is slow

Fable is discursive, 5.6 is detailed.

@marclou Good one

I made TrustMRR readable by AI agents. AI Agents often miss data when they have to scroll pages or run scripts. The goal is to make the startup marketplace easier to browse from ChatGPT, Claude, Gemini, and other AI assistants, so people can discover and acquire startups from chat. So I added public startup .md pages, llms.txt, and a limited /api/ai endpoint to give agents structured data. ChatGPT alone makes nearly as many daily requests as actual humans on TrustMRR. So I'm giving all my startups the best surfboard to ride the AI tsunami.

@fidjissimo Wishing you a full recovery, Champ. Take care and come back stronger ❤️

Today, I shared with the OpenAI team that I have decided to leave my full-time role at OpenAI and transition to being a part-time advisor. Three months ago, I had to go on medical leave after a severe exacerbation of a chronic illness I’ve lived with for seven years. During that time, it became clear that the road to recovery would be much longer and more complex than I had anticipated—and that I needed to focus on it fully. When I went on leave, many people told me I was courageous for prioritizing my health. The truth is that I am only making this decision now because I failed to make it many times before. Over the years, doctors, friends, colleagues, and loved ones encouraged me to slow down. Two years after I got sick, Facebook offered me the opportunity to take a full year of medical leave. I didn’t even pause to consider it. I immediately said no. At the time, Zuck told me I should play the long game. I wish I had listened. Looking back, I realize that a lot of what made me successful also made this decision incredibly difficult. I grew up believing that opportunities were precious and that when they appeared, you grabbed them with both hands. That mindset carried me from a small town in southern France to opportunities I never could have imagined. By the time I turned 40, I had already gotten to do more than I’d ever dreamed possible as a kid growing up in Sète. I love building. My work has always given me a deep sense of purpose. OpenAI in particular felt like a role that my entire career had been building toward, which made this decision even harder. But what I’m learning now is that grit and endurance are not the only skills required to have impact over decades. Sometimes the harder thing is to stop, listen, and trust that taking care of yourself today makes it possible to contribute for much longer tomorrow. This experience has also strengthened my conviction about why this work matters. It has been a jarring experience to spend my days helping build the future while simultaneously navigating a disabling disease that still has no cure. Over the last seven years, I’ve spent countless hours in doctors’ offices, dealing with symptoms, treatments, insurance, uncertainty, and all the invisible work that comes with being a patient. Like millions of others living with chronic illness, I’ve experienced firsthand how difficult healthcare can be to navigate, even when you have every possible advantage. More than ever, I believe that some of the most important opportunities for AI lie in helping people solve real problems in their daily lives: their health, their finances, their time and the everyday burdens that shape human experience. In particular, curing disease is the most important thing AI could accomplish. I’m excited to continue working towards cures through OpenAI but also through my work with @ChronicleBioAI and @CODA_research. I’m deeply grateful to @sama, @gdb and the OpenAI board for their support during this time and for offering a way for me to continue contributing to the mission without sacrificing my chances of recovery. I’m also so thankful to my team and the many extraordinary colleagues I’ve had the privilege to build alongside. For now, my focus is recovery. But my belief in the potential of technology to solve deeply human problems has never been stronger.
