As models become more capable, the risks associated with developing and testing them internally also grow. We temporarily paused reinforcement learning (RL) training on our latest models intended for deployment for two weeks while we hardened and red-teamed our research environments and expanded monitoring coverage. Our largest planned frontier RL run remains on hold while smaller-scale training and evaluations validate these safeguards and establish more evidence of alignment. https://t.co/ecbMMmVoox

Anthropic is working on a Hub Mode 👀 * Speculation - It might be related to an interface where Claude will be operating multiple sub-agents and visualizing the overall progress to the user. https://t.co/N4aIgmXAHD
