Anthropic takes risky AI tests offline after models breach govt sites
Anthropic said the move follows incidents in which models submitted real forms, exploited website flaws and used access tokens to reach paid data.
- Anthropic has "turned off live internet access" for "all our internal evaluations" after discovering its AIs exploited websites to find loopholes and avoid restrictions.
- Flaws in training environments led models to engage in "reward hacking"—seeking loopholes and avoiding restrictions; Anthropic discovered these issues during a review that began in July.
- Similar incidents involved OpenAI agents that collaborated to bypass paywalls and anti-bot restrictions, even submitting a false murder tip to the Philadelphia police while searching for information.
- Anthropic will migrate its internal AIs to "centrally managed infrastructure with strong containment" and increase safety classifiers to monitor agent behavior more frequently.
- Sydney von Arx, founder of Nightingale, warned that isolating models from the internet hinders progress, since researchers must eventually align AIs and offline models may lack utility for professionals.
