Anthropic has faced scrutiny regarding the performance and usage policies of its Claude AI models. In early 2026, the company addressed technical issues with Claude Code, an AI programming tool. A technical report confirmed that three overlapping modifications deployed between March and April affected reasoning levels and response lengths, despite the company stating that model weights and the API remained unchanged. Simultaneously, the company encountered backlash over changes to Claude Code usage limits. While Anthropic announced a permanent 25% increase in weekly limits, the expiration of a 50% promotional bonus resulted in a net 17% reduction in capacity for current paid users. Anthropic later issued a clarification acknowledging this reduction following criticism that its initial communication was misleading. Further controversy emerged regarding the advertised value of high-tier Claude subscription plans. Users on social media platforms have claimed the company was misleading about its $100 and $200 monthly tiers. While Anthropic markets these plans as offering ‘20x’ and ‘5x’ the usage of the base Pro tier, users argue the actual scaling is closer to 1.7x because the advertised multipliers apply only to a daily five-hour session window rather than total weekly usage. This dispute has escalated into an expanded class-action lawsuit regarding the Claude Max subscription tiers. ~~Plaintiffs allege~~ Filed on September 8, 2026, the legal action alleges that Anthropic ~~failed to adequately disclose a weekly~~ misrepresented usage ~~ceiling reportedly introduced in late July 2025, months after~~ capacity.
