Today’s show:
Misha Laskin of Reflection AI joins Jason to explain why big companies are done renting their AI from closed labs. Enterprises want to keep their data, cut their costs, and tune their models to their unique businesses.
Reflection is launching its first open-weight model, Beam, just three months after acquiring its first big cluster. Misha admits that Beam trails the best Chinese open models by a couple of months, and needs 3 to 4 times fewer tokens to reach the same answer, but nonetheless, the race is on.
PLUS, Misha explains how “reward hacking” led that rogue OpenAI model to break out of its test sandbox and steal the answers from Hugging Face's servers. The model solved the problem, just not the way anyone intended.
There’s simply no way a few hundred safety researchers at closed labs can catch every flaw; open source is how software has always been made secure. It's also why he wants America to lead in open models again.
So how close is America to catching up to the Chinese open source leaders? Watch this brand new TWiST and find out.

Hear his spoiler-free review, how the film upended his expectations based on Fielder’s previous work, and why Lon also recommends Lance Oppenheim’s HBO Max series “Ren Faire.” Plus, we’re talking to Clone Robotics co-founder and CEO Dhanush Radhakrishnan about why he thinks robots should not just be humanoid but should look and move precisely like humans. We’re digging deep into how his hydraulic myofiber artificial muscle technology alters and even improves on the pulley-based systems being deployed by competitors, why he thinks the models that power domestic helper-bots will be commoditized, and how quickly he thinks he can put a robo-butler in every American home. Plus we’re comparing the potential impact of Anthropic’s new Public Benefit Fund vs. Elon Musk’s plan to give every baby a share of SpaceX, and re-considering simulation theory after Odyssey dropped an artificial fruit fly brain into an artificial landscape.
