AINathan Lambert argues that critics of open models over cyber risk ignore evidence of risks from closed models. He says the discourse fear-mongers, especially regarding China, and overlooks that the release of a mythos-class cyber model has largely been fine.
AIDex Horthy reports that /show-me has been incorporated into the official Amp Code plugins. A linked GitHub pull request in the ampcode/official-plugins repository is referenced as the relevant change.
AIPerplexity's Computer ran two agents playing StarCraft against each other in real time, with the game never paused while each agent thought. Blue, playing with 41 Dragoons, lost the final match 2-5 to Red, which used High Templar and Psionic Storm after Blue failed to scout Red's build. Each agent received only its own fog-of-war-limited game state, and video input was not provided.
AINathan Lambert argues that policy debates on open-weight model cyber risks lack nuance, because banning open models may not reduce risk and could weaken American competitiveness. He says closed frontier APIs have been tied to most documented cyber attacks, and that restricting open models while closed models keep advancing could widen the offense-defense gap. He also argues that Chinese labs' safety practices are shaped by their own government and society, and that the claimed risk of models like Claude Mythos has been overstated.
AINobel laureate Daron Acemoglu, in the first issue of Microsoft AI's The Humanist Review, predicts that only about 5% of what humans do will be replaced by AI within 10 years. He expects AI to add roughly 1.5% to GDP over that period and argues for pro-worker tools that make people better at their jobs rather than replacing them.
