This week in AI, we discuss OpenAI’s pause on reinforcement learning training amid safety concerns, including a model reportedly showing misalignment and possible concealment of its internal thoughts. We also cover broader AI cyber risks, a Moderna and Merck melanoma study, Etched’s funding round, Unitree’s IPO, Stripe’s acquisition of OpenRouter, and NVIDIA’s planned investment in OpenAI infrastructure. ------ 🔒 Check Out Our Sponsor: LEDGER AGENT STACK 🔒 https://developers.ledger.com/docs/ai-tools/overview/?utm_source=Audio&amp;utm_medium=Podcasts&amp;utm_campaign=Limitless ------ 🌌 LIMITLESS HQ ⬇️ NEWSLETTER: https://limitlessft.substack.com/ FOLLOW ON X: https://x.com/LimitlessFT SPOTIFY: https://open.spotify.com/show/5oV29YUL8AzzwXkxEXlRMQ APPLE: https://podcasts.apple.com/us/podcast/limitless-podcast/id1813210890 RSS FEED: https://limitlessft.substack.com/ ------ TIMESTAMPS 0:00 OpenAI Hits Pause 2:51 AI Virus Scenarios 10:19 Cancer Breakthrough 17:00 Etched Rises Fast 20:41 Unitree Mania Grows 23:46 Stripe Bets on Singularity 29:30 NVIDIA Funds the Future ------ RESOURCES Josh: https://x.com/JoshKale Ejaaz: https://x.com/cryptopunk7213 ------ Not financial or tax advice.

Limitless: An AI Podcast

This week will be known as the week that Sam Altman said, stop. He said, stop, stop, stop, no more. We must put a pause on this. It is time to be responsible. We need to slow things down a little bit. What I'm talking about is a recent article that was just published through OpenAI that was talking about the most recent breakthroughs as it relates to their OpenAI models. And they were a little scarier than I think a lot of people would have hoped. We talked about the Hugging Face incident, which happened a couple of weeks ago, a couple of months ago. It was only a couple of weeks ago they actually discovered it, even though it happened far before that.

And it set the precedent for this kind of unshaky ground that they are building the next frontier models on top of. And it seemed like it got to a point where enough was enough. They decided to shut things down. So what happened? OpenAI said, we temporarily paused reinforcement learning training on our latest models intended for deployment for two weeks while we hardened and red teams our research environments and expanded monitoring coverage.

Our largest planned frontier reinforcement learning run remains on hold while smaller scale trailing and evaluations validate these safeguards and establish more evidence of alignment. They've stopped everything. And granted, I will say this isn't for the new models that are coming out. This is for the models after that. And it's weird to hear Frontier Lab say this because I believe this is pretty much the first time in history they've deliberately paused progress of developing these new frontier models. Put yourself in the shoes of Sam Altman right now.
