1st 👼 angel money right here. Rahul applied to speak at AI Tinkerers in SF few yrs ago - I thought it was amazing, met him before he presented, intro’d him to seed investors. This ambitious vision coming to life!

security self audit in 2026:
step one: find the Cloudflare skill and run it using a frontier model from OpenAI or Anthropic.
step two: get flagged and prevented from running it.
step three: ask your agent to find an open model that's not restricted and start running it on Open Router, sending all your info and vulnerabilities to an inference provider in China.
On the standard endpoint, routing can go anywhere, including Chinese providers. Cost-based or automatic routing often picks the cheapest option, which is frequently the Chinese-hosted version
Celebrated 2-yr Bday of AI Tinkerers - Hong Kong, with Tim Chau (lead organizer and chapter founder) on a harbor cruise with the community - don't sleep on HK. The depth and innovation is impressive.
Can get a strong sense of the startup ecosystem from the first 15 mins of an AI Tinkerers meetup and i can tell Da Nang is rising from quality of the discussions and demos
Dropped in at AI Tinkerers - Kuala Lumpur and met entrepreneurs, roboticist, grad students and builders from KL and around the region who now call KL home! @jacoblaes @joschafeth @andreteow @500GlobalVC

⛰️TERRA is a very interesting and impressive work led by Merkourios Simos @amathislab
It substantially expands the terrain diversity we can train and evaluate MuscleMimic controllers on, going beyond flat-ground motion to diverse, non-flat environments reconstructed directly from motion data.
Huge thanks to folks who's work made this possible, @CaggianoVitt and the @MyoSuite team, @CherylWang39256, Bianca Ziliotto, @TrackingPlumes and MuscleMimic team, and the amazing teams at @GoogleDeepMind and @nvidia behind mujoco warp.
Exciting to see how quickly the field is progressing, and especially what this opens up for biomechanics and neuroscience. Please checkout our paper at: arxiv.org/abs/2609.38653
