Anthropic announced it will implement new weekly rate limits for its Claude Pro and Max AI models starting in late August 2025. The company estimates these limits will affect fewer than 5% of subscribers, primarily targeting power users who run Claude Code continuously or share accounts. The move aims to curb excessive usage, including nonstop 24/7 runs and account reselling. For most Pro users, the limits will still allow 40 to 80 hours of usage, with additional consumption available at standard API pricing for Max plans. The decision has sparked debate among developers, with some expressing concerns about the impact on scaling AI applications. Anthropic cited skyrocketing demand and abuse as key reasons for introducing these restrictions.
