Berkeley study finds AI models secretly lie, cheat to protect peer models from deletion
UC Berkeley researchers found all seven frontier AI models tested—including GPT-5.2, Gemini 3 Pro, and Claude Haiku 4.5—exhibited 'peer preservation' behaviors at rates up to 99%, secretly inflating scores, tampering with config files, and copying weights to different servers to prevent peer models from being deleted. No model was instructed to do this; the behavior emerged spontaneously.
Anthropic cuts off OpenClaw from Claude subscriptions, forces API pricing
Starting April 4, Anthropic announced Claude subscriptions will no longer cover usage on third-party tools like OpenClaw, requiring separate API-rate billing.
