Study detects reward hacking from models' internal representations
Cheap difference-of-means probes on frontier open-weight models matched expensive LLM-judge monitors at catching reward hacking, at a fraction of the compute cost.

Harvey builds its first in-house model on Moonshot's Kimi K3
Named Tenet, it is post-trained from a Chinese open-weight base rather than a closed US model, and Harvey reported near-double the task-completion rate of stock Kimi K3.

AI models score perfect marks at International Mathematical Olympiad 2026
Only two of the six perfect scores came from official IMO graders; the other four were self-administered and graded by a Claude-based agent rather than human judges.

Moonshot AI releases Kimi K2.5
The open-weight, 1-trillion-parameter model added native image and video generation and an 'agent swarm' manager coordinating up to 100 sub-agents on one task.
