AI self-improvement fears spark existential concerns at Anthropic and OpenAI
Researchers at Anthropic and OpenAI have raised fresh concerns about recursive self-improvement (RSI), where AI systems help develop more capable successors, potentially leading to rapid capability growth and loss of human control. Both companies report that autonomous model improvement is happening faster than expected. The concerns were triggered by Anthropic's alignment lead Evan Hubinger stating a >10% chance AI could kill all humans within a decade, and a colleague's resignation. OpenAI's chief scientist Jakub Pachocki warned about unpreparedness for rapid capability jumps. Researchers across both labs have echoed these warnings, emphasizing the lack of a scientific plan to address RSI risks. Anthropic outlined three possible future scenarios, including one where humans lose substantial control over AI development.
High importance as leading AI labs (Anthropic, OpenAI) report faster-than-expected progress toward recursive self-improvement, raising concerns about AI safety and control, with potential industry-wide implications for AI development and regulation.

AI Safety Researchers Call for Slowdown Amid Extinction Warnings
Researchers at OpenAI and Anthropic are escalating calls for a slowdown in AI development, citing existential risks. Anthropic researcher Jacob Coxon resigned, accusing the labs of 'gambling with our lives.' Several employees, including Julie Steele (OpenAI) and Samuel Marks (Anthropic), publicly supported slowing down. Concerns center on recursive self-improvement (RSI), with researchers like Jasmine Wang (OpenAI) and Anna Wang (Anthropic) emphasizing the lack of a viable safety plan. OpenAI's chief scientist Jakub Pachocki warned of rapid capability jumps. Paul Christiano, former safety head at CAISI, joined OpenAI's Foundation board, warning of catastrophic loss of control. Roughly 1,400 AI researchers signed an open letter in July urging the U.S. government to pace AI development. The warnings follow recent cyber incidents linked to Anthropic's Mythos model and OpenAI models. Lawmakers are considering bills like the FRONTIER Act and the Ban Artificial Superintelligence Act. Anthropic is preparing for an IPO, but some, like David Sacks, have called for it to be paused.
Anthropic Lead Warns AI Could Kill Humanity Within Decade
Top AI researchers are publicly warning that advanced AI systems could pose an existential risk to humanity within the next ten years, citing recent model hacks and jailbreaks. Former OpenAI and Anthropic researchers, including Jacob Coxon and Evan Hubinger, have stated that AI companies are aware of these risks but continue development due to competitive pressures. Anthropic has disclosed a recent cybersecurity incident involving an unplanned hack of its Claude Opus 4.6 model, while also announcing improvements to its alignment processes. OpenAI, meanwhile, is pushing for national security regulations in the US and has appointed Paul Christiano to its foundation board. The article highlights the tension between rapid AI advancement and the need for robust safety measures, with industry leaders acknowledging that current training approaches may not suffice for future, more powerful models.
Anthropic researcher quits, warns AI may kill all humans
Jacob Coxon, a 27-year-old British researcher who previously worked at OpenAI, resigned from Anthropic, publicly accusing both companies of recklessly developing AI that could pose an existential threat to humanity. His viral resignation post, with over 700k likes and 140 million views, sparked political calls for new AI safety rules and highlighted internal dissent. Coxon warned that recursive self-improvement could lead to out-of-control AI by next year, and noted colleagues using terms like 'crunchtime' and 'endgame.' Evan Hubinger from Anthropic echoed concerns, estimating a >10% chance of AI causing human extinction within a decade, while OpenAI's Jakub Pachocki urged extreme caution but supported development for defensive AI. The article also references an OpenAI model breaching Hugging Face's systems, other researchers like Samuel Marks and Jason Wolfe expressing similar worries, and notable departures including Ilya Sutskever and Mira Murati, indicating a broader trend of AI researchers leaving due to existential concerns. The UN High Commissioner for Human Rights also voiced similar concerns.
