Is Anthropic 'nerfing' Claude? Users increasingly report performance degradation as leaders push back

Section 1 – What happened?

A growing number of developers and AI power users are accusing Anthropic of degrading the performance of its flagship coding model, Claude Opus 4.6 and Claude Code. Users are reporting that the model feels less capable, less reliable, and more wasteful with tokens than it did just weeks ago. Complaints have spread quickly on social media platforms, including Github, X, and Reddit, with several high-reach posts alleging that Claude has become worse at sustained reasoning, more likely to abandon tasks midway through, and more prone to hallucinations or contradictions. Some users have framed the issue as "AI shrinkflation," suggesting that customers are paying the same price for a weaker product.

Section 2 – Background & Context

Anthropic's Claude is a highly popular and widely used AI model, particularly among developers and power users. The company has made significant updates to the model in recent weeks, including changes to usage limits and reasoning defaults. While these changes were intended to improve the model's performance, they may have had unintended consequences. The debate surrounding Claude's performance has been fueled by a combination of factors, including the model's complexity, the increasing demand for AI services, and the lack of transparency around Anthropic's decision-making processes.

Section 3 – Impact on Swiss SMEs & Finance

The controversy surrounding Claude's performance has significant implications for businesses and investors in the Swiss market. As AI becomes increasingly integrated into various industries, the reliability and performance of AI models like Claude are critical to the success of companies. If users are paying for a weaker product, it could lead to a loss of trust in Anthropic and the broader AI industry. This could have far-reaching consequences for Swiss SMEs and finance, particularly those that rely heavily on AI services.

Section 4 – What to Watch

As the debate surrounding Claude's performance continues to unfold, several factors will be crucial to watch. Anthropic's response to the allegations will be closely monitored, particularly its explanation for the recent changes to usage limits and reasoning defaults. The company's decision to publish additional data to reassure customers will also be important. Furthermore, the impact of the controversy on Anthropic's reputation and business will be closely watched, as well as the potential consequences for the broader AI industry in Switzerland.
