AI fixes AI in MIT study, Mistral's open model & Google Genie 4

Visit Mixture of Experts podcast page to get more AI content → https://ibm.biz/~Rz77ywquX How close are we to AI that can improve itself? This week on Mixture of Experts, guest host Aili McConnon is joined by Chris Hay, Sascha Brodsky and Kiyu Gabriel tackle that question and more from the latest AI headlines. First, MIT researchers demonstrate a technique that uses AI to modify another model's weights. The panel considers how close this brings us to recursive self-improvement and whether reward hacking poses a more immediate risk. Next, Mistral releases a trillion-parameter open-weight model while NVIDIA expands its open model offerings. With open models approaching frontier-level capabilities, will developers still need to rely on proprietary AI? Finally, Google DeepMind introduces Genie 4, its new world model. The panel debates how much these models actually understand about physics and what happens when a convincing simulation gets the real world wrong. All that and more on Mixture of Experts. 00:00 – Intro 01:08 - AI self-improvement and MIT's research 16:28 - New open models from Mistral and NVIDIA 25:27 - Google’s Genie 4 simulates 3D worlds "The opinions expressed in this podcast are solely those of the participants and do not necessarily reflect the views of IBM or any other organization or entity.
