Anthropic Confirms Claude Code Quality Problems and Promises Stricter Controls

Apr 24, 2026

Anthropic acknowledged quality problems with Claude Code after developers complained about declining performance and accused the company of secretly downgrading its Opus 4.6 model, while the newer Opus 4.7 drew mixed reviews over bugs and higher token costs. The AI company identified three sources of error and promised stricter quality controls as it grapples with surging demand that has strained compute capacity, caused a security breach exposing internal files, and led to confusion when Claude Code was removed from some $20 Pro plan subscriptions as part of a limited test. The troubles come as Anthropic faces a potential $800 billion IPO and intensifying competition from OpenAI, whose executives have publicly criticized Anthropic as elitist and accused it of overstating revenue while courting frustrated developers. Despite the operational challenges spanning product quality, pricing, security and capacity over two months, Anthropic's revenue has tripled to $30 billion this year and demand remains strong as the company pushes enterprise clients toward usage-based pricing.
