Anthropic CEO Calls for AI Development Slowdown After Researcher Exit

Anthropic CEO Dario Amodei publicly urged artificial intelligence companies to decelerate their development efforts, marking a significant shift in tone from one of the industry's leading figures on AI safety.

The statement, posted to Amodei's personal website Saturday, follows the departure of AI researcher Jacob Coxon from the field. Coxon, who previously worked at OpenAI before joining Anthropic, left the industry entirely days earlier with a stark warning that AI firms are "gambling with our lives" as they race to build self-improving models.

Why it matters

Amodei's call represents a notable escalation in concerns about AI development pace from within the industry itself. As CEO of a company backed by billions in funding and competing directly with OpenAI, his willingness to advocate for slower progress signals that safety worries may be reaching a critical threshold even among those building the technology. The departure of researchers like Coxon over ethical concerns adds pressure on AI companies to demonstrate they can balance innovation with responsible development.

A Shift Toward Caution

"We must slow the pace at which we improve the capabilities of AI models," Amodei wrote. "Progress will still seem fast, and we must make wise use of the time we gain."

The CEO acknowledged the fundamental tension facing AI developers: building too slowly could cede advantages to authoritarian governments, while moving too quickly courts serious risks. Amodei said Anthropic has attempted to navigate a "middle way" since he and his sister Daniela co-founded the company in 2021.

However, he indicated his position has evolved. "Over the last few months, I have become convinced that fully addressing the risks requires even more prudence," Amodei stated.

Growing Concerns Over Superintelligence

The warnings center on the potential emergence of superintelligent systems—AI models that could surpass human capabilities and potentially improve themselves without human oversight. Coxon's decision to leave both OpenAI and Anthropic underscores the depth of concern among some researchers that current safety measures may prove inadequate.

Amodei framed AI as "such a powerful technology" that its associated risks must be treated as serious threats. His statement stops short of calling for a complete halt to development, instead advocating for a measured reduction in the velocity of capability improvements.

Industry Implications

The public nature of Amodei's comments may increase pressure on competitors to address safety concerns more transparently. Anthropic has positioned itself as a safety-focused alternative to other AI labs, but Coxon's departure suggests even companies emphasizing responsible development face internal tensions over the pace and direction of their work.
