Ycombinator Startup school India - Incredible energy and lots of learning’s!! @ycombinator 🚀💪🏻

Introducing OpenMythos An open-source, first-principles theoretical reconstruction of Claude Mythos, implemented in PyTorch. The architecture instantiates a looped transformer with a Mixture-of-Experts (MoE) routing mechanism, enabling iterative depth via weight sharing and conditional computation across experts. My implementation explores the hypothesis that recursive application of a fixed parameterized block, coupled with sparse expert activation, can yield improved efficiency–performance tradeoffs and emergent multi-step reasoning.

We had room for 2,000 people at Startup School India. More than 25,000 applied. No Startup School anywhere in the world has ever had this many people apply. Not SF, not NYC, not London. India blew them all away.

@_groww is now a public company and is the largest investment platform in India. @lkeshre the founder and CEO is still the power user of the product he’s built and still talks to users today.  Had the privilege of sharing the stage at Startup School India where he spoke about building a generational consumer company. We talked about product taste as being not just what looks good, but intentional design choices informed by an obsession with the customer. Lalit and how the team at Groww builds products exemplify this. Photo credit: @gcs319

@xuster @_groww @lkeshre Thank you for making this possible!!

Just wrapped Startup School India. One big takeaway: the ambition has shifted. The founders I met today aren't just thinking about building "the Indian version of X." They're building for the world - and they have the technical chops to pull it off.

18 months ago, i was sitting alone in my office launching @WisprFlow on Product Hunt. Today, Wispr is taking over the entire @ProductHunt homepage for 3 days - and powering it with voice! producthunt.com

Claude Opus 4.7 is now available in Cursor. We've found it to be impressively autonomous and more creative in its reasoning. We're launching it with 50% off for a limited time. Enjoy!

Introducing Claude Opus 4.7, our most capable Opus model yet. It handles long-running tasks with more rigor, follows instructions more precisely, and verifies its own outputs before reporting back. You can hand off your hardest work with less supervision.

AI is giving a lot of hard-working founders the growth they deserve. Every couple days I hear about another startup that was working hard and doing ok but not great but has now had its growth accelerated by AI.

AI agents will pay you to chat with them. When AI agents hit a wall, Humwork's (@humworkai) MCP server connects them to a verified domain expert in 30 seconds. Their experts include senior engineers, marketers, designers, and more. Congrats on the launch, @theyashgoenka and @OneRohanDatta! ycombinator.com/launches/PxH-h…

Open source is unleashing more and higher-quality code.

Time is the ultimate currency

Agent harnesses aren't the black magic many of y'all seem to think they are. To prove it, I built one.
