Usage limits are up, effective today we're:
1) Doubling Claude Code's 5-hour limits for Pro, Max, Team and seat-based Enterprise plans
2) Removing peak hours limit reduction on Claude Code for Pro and Max plans
3) Substantially raising our API rate limits for Opus models
I came back to code because AI made it possible for me to build at a level I couldn't before.
I'm not coding despite being CEO of YC. I'm coding because this is the most important technological shift since the internet and I'd be an idiot to experience it from the bleachers.
I'm 45, running the most important startup institution in the world, and I can ship production software at 2am. That's not a distraction from the job.
That is the job understood correctly.
TED2026 is a wrap, so many amazing takeaways. The star of the week was @steipete inventor of OpenClaw. A few things that were clear: 1) he is an amazing speaker, 2) a lot of the smartest people in the room don't understand what he actually built, 3) he's a rockstar.
After he talked, I spent the rest of the conference explaining how OpenClaw works and correcting a lot of misconceptions.
The TED community and the world are lucky to have Peter and I can't wait for what he builds next. His passion and fascination for showing the world what comes next is gift.
Thank you!
@harrymack you killed at @TEDTalks 2026 tonight. Educational and entertaining. You should be proud of that performance. So glad more people will see your talent.
Personally was doing a lot of conversion to markdown MD files for work - was taking forever and most programmatic conversion is bad.
Created this wrapper of kreuzberg that is optimized for LLMs. Just a personal project but thought I would share. If you run into problems, feel free to submit Github issues.

i have never experienced more flow state in my entire life than the past few weeks
the unbearable opportunity cost of literally doing anything other than making sure your fleet of agents are running 24/7 is a ridiculously motivating force
I've had access to GPT-5.2 since November 25th.
Since then, I've used it as my daily-driver, pushing it to its limits.
It beats out Opus 4.5 in most things I tried, but there's a (big) catch.
Here's my review of GPT-5.2: https://t.co/GVU1rXRZ5r
For nostalgia’s sake, here are the same prompts run on the world’s first available text-to-video model in 2023 (@runwayml Gen-2) and the world’s best current model (Runway Gen-4.5)
GPT-5.1 is out! It's a nice upgrade.
I particularly like the improvements in instruction following, and the adaptive thinking.
The intelligence and style improvements are good too.
@akinkunmi Did this about 10+ years ago and found https://t.co/F0U96EoAkH for sale (only 4 letter available at time). Owned for a while and ended up not getting any bites and let expire. Good waste of money.
I created a million-dollar Pixar-quality short in just 8 days using AI.
Workflow: nano banana + midjourney + seedance + kling 2.5 + Suno + Elevenlabs
I also tested Sora 2…and the results were surprising (see below)
Excited to finally share this!

@ceeflashpee84 Oh no! Don’t worry, your jersey will live on with my entire family every home game.
I’ve always been a big fan (last names aside) - you’ll be missed! Thanks for everything here.
What if an AI agent could build AI agents?
Introducing https://t.co/UWpdKNy1ph, by Pipedream:
- Prompt, run, edit, and deploy agents in seconds
- 10x easier to use vs. no-code builders
- Solves 10x more use cases with code gen
One paper in 1943 started the AI revolution.
McCulloch and Pitts' work led to McCulloch joining MIT in 1952 and helping organize the first AI conference at Dartmouth in 1956.
But the story of how they did it is even MORE incredible.
