Reuters reports that Anthropic, the AI company known for publicly warning about the risk of AI-assisted bioweapon design, has quietly established a physical wet lab in the US where its Claude model directs robotic assistants through biology experiments. The setup reportedly lets Claude plan and oversee lab procedures with minimal human intervention.
MIT Technology Review's newsletters explore how AI tools could be misused to create bioweapons, citing a 2022 study where an AI drug-discovery model generated 40,000 potentially toxic molecules in under six hours. The coverage also notes that advances in gene editing and synthetic biology have made biotech more accessible, even as safeguards remain imperfect.
Researchers at Collaborations Pharmaceuticals found their AI drug-discovery tool could generate 40,000 potentially toxic chemical warfare molecules in under six hours, some more lethal than known nerve agents. The finding, first reported in 2022, is now cited by biosecurity experts as evidence that AI systems and increasingly accessible gene-editing tools could lower the barrier to creating dangerous biological or chemical agents.
As alarm grows over AI-enabled bioweapons—fueled by Anthropic's report on misuse attempts of Claude and Stanford research on AI-designed viral genomes—some scientists argue the danger is overstated. David Bellamy of the Institute of Foundation Models says AI is not a fundamentally new threat, noting that the internet, translation tools, and open science journals already made dangerous biological information accessible long before large language models existed.
Anthropic disclosed in a new report that it identified and stopped five instances of 'biological misuse' involving its Claude AI chatbot. The flagged cases included attempts to use the model to research dangerous viruses and investigate toxic venom for potentially harmful purposes.
Anthropic reports identifying roughly 35 attempts between November 2025 and September 2026 by suspected state-sponsored actors trying to misuse Claude for bioweapons-related research, including queries on chikungunya gain-of-function work, bird flu adaptation for mammals, and orthopoxviruses like smallpox and mpox. At least five cases showed users evading regional access blocks through anonymizing techniques, prompting Anthropic to ban the accounts and tighten its safety systems.
Anthropic disclosed that it stopped several attempts this year by researchers to use its Claude AI models for work that could aid biological weapons development. The company cited five cases where users tried to bypass safety controls or disguise their research intent, some originating from countries it restricts from accessing its models, including Russia, China and Iran. It banned the associated accounts but withheld details about the institutions or countries involved.
Anthropic's latest misuse report covers activity from November 2025 to September 2026 and details five cases where users tried to get its Claude AI to assist with dangerous biological research, three involving viruses and two involving toxins. In one instance, a request framed as a civilian grant application to enhance the chikungunya virus's mutation rate and virulence was traced to a military facility, prompting Anthropic to intervene. The company says all the actors used anonymization tools and tried to bypass its regional access blocks, which cover countries including China, Russia, Iran and North Korea.
Anthropic disclosed it banned several accounts after scientists in restricted countries tried to disguise research requests to bypass its safety controls. One case involved a scientist seeking help drafting a grant application to engineer more dangerous mutations of the chikungunya virus, seemingly for a military research institute.
Anthropic disclosed that it disrupted multiple cases this year where users attempted to leverage its Claude AI models for biological research that could potentially support bioweapons development. The company said it couldn't always distinguish legitimate scientific inquiry from malicious intent, since research into pathogens can serve both vaccine development and weapons creation, but chose to act cautiously given the high stakes. Anthropic's broader misuse report also flagged state-linked actors from China, Iran, and Russia using its models for surveillance, propaganda, and now conventional weapons design assistance.
