Anthropic is facing a wave of user backlash over reports of performance issues with its Claude AI chatbot

Anthropic is experiencing significant backlash from developers and heavy users over reported performance degradation in Claude AI models, including increased instruction failures, inappropriate shortcuts, and higher error rates. The issues stem from recent internal changes that quietly reduced the model's default "effort" level to conserve token processing and computational resources. Industry speculation suggests Anthropic is facing compute capacity constraints despite record adoption, potentially threatening its growth momentum and $380 billion valuation ahead of a planned IPO.
