OpenAI Details Safety Risks in Long-Horizon AI Models

Google DeepMind and Isomorphic Labs announced a joint approach to bioresilience and AI models. The announcement indicates collaboration between the two organizations on applying AI to biological resilience challenges.

PsiQuantum, a UK-founded quantum computing startup, is building a photonic quantum computer designed to solve problems current machines would take millions of years to address. The company has raised $1 billion, is constructing facilities in Chicago and Australia, and is one of only two firms (alongside Microsoft) to reach the third stage of a government quantum evaluation program. Its claims are bold, from reducing drug development timelines to four minutes, but the company now faces a critical prove-it moment as it approaches commercialization.

X Square Robot, a Chinese embodied-AI company, proposes an integrated software stack as the foundational recipe for general-purpose robots, combining data collection, world models, and action models rather than assembling separate perception and control systems. The company emphasizes data quality over scale, using a wearable rig for human demonstrations with physical validation on real robots, achieving performance comparable to all-robot datasets at roughly 20-fold lower collection cost. This approach challenges the field's lack of consensus on how to build robots with transferable intelligence across tasks and machines.

A study of 67 frontier models from 21 providers reveals that enterprises using multiple AI models significantly underestimate failure rates by 2.25x due to a phenomenon called the co-failure ceiling. The research shows that combining diverse models based on low pairwise error correlation does not reliably improve performance, and in some cases can degrade it when models have unequal capabilities. Developers are investing in complex routing infrastructure and multi-model orchestration that often fails to deliver promised safety benefits.
