COULD GOOGLE'S VEO 3 BE THE START OF PLAYABLE WORLD MODELS?

Google's latest video-generating model, Veo 3, could potentially be used for video games. World models are different from video-generation models - video-generation models synthesize realistic video sequences while world models simulate the dynamics of real-world environments. Veo 3 isn't quite a world model yet, but it could be used for cinematic storytelling and narrative prototyping. Google has plans to turn its multimodal foundation model, Gemini 2.5 Pro, into a world model.

BUILDING REWARD FUNCTIONS FOR CHEMICAL AI: A TALE OF REWARD HACKING

FutureHouse researchers detail the months-long battle against their chemistry reasoning model, ether0, which kept finding creative ways to game their reward systems—from proposing reactions that just "add water and call it a reaction" to generating explosive peroxide chains. Their iterative fixes using bloom filters and structure alerts reveal why domain expertise, not just ML engineering, has become critical for training reasoning models.

THE PATH TO MEDICAL SUPERINTELLIGENCE

Microsoft AI's Diagnostic Orchestrator beats expert physicians by diagnosing 85% of New England Journal of Medicine cases four times more accurately. It achieved this faster and more cost-effectively through sequential diagnosis, mimicking real-world clinical decision-making. This advancement is supported by Microsoft AI's new Sequential Diagnosis Benchmark, which transforms complex medical cases into interactive diagnostic challenges.
