The Canadian government announced that OpenAI CEO Sam Altman has agreed to implement additional safety measures for its AI services. The move follows a high‑school shooting where OpenAI flagged the suspect but did not alert authorities. New protocols will focus on law‑enforcement notifications, retroactive review of suspicious activity, and collaboration with Canadian privacy, mental‑health and law‑enforcement experts. OpenAI has pledged to provide a report outlining these changes, building on earlier efforts to tighten detection systems and prevent banned users from returning to the platform.Lire la suite

Anthropic's $200 million Department of Defense contract fell apart over a clause allowing unrestricted military use of its AI. After the Pentagon turned to OpenAI, Anthropic CEO Dario Amodei resumed talks with Pentagon official Emil Michael to seek a compromise that would limit uses such as domestic surveillance and autonomous weapons. Both sides have exchanged sharp criticism, and Defense Secretary Pete Hegseth has threatened to label Anthropic a supply‑chain risk, a move that could bar the company from future military‑related work.Lire la suite

In 2026, artificial intelligence can draft emails, summarize meetings, write code, and create caricatures, yet it still falls short in several key areas. Large language models often hallucinate, presenting fabricated facts with confidence. They struggle with simple counting tasks, lack the lived experience needed for therapy, cannot update knowledge in real time, and remain unable to truly understand human nuance. Recognizing these boundaries helps users apply AI tools responsibly and avoid costly mistakes.Lire la suite

Researchers from ETH Zurich, Anthropic and the Machine Learning Alignment and Theory Scholars program have built an automated AI system that can link pseudonymous online profiles to real identities. Using large language models to analyze writing style, posting patterns and other clues, the system correctly matched up to 68 percent of accounts with 90 percent precision, far outpacing traditional methods. The experiment cost only a few dollars per profile, highlighting a low‑cost barrier for large‑scale deanonymization. The study warns that online anonymity may be less secure than many assume, especially as AI capabilities continue to improve.Lire la suite

Anthropic CEO Dario Amodei has re‑opened talks with the U.S. Defense Department after a dispute over contract language concerning the use of the company’s AI models for bulk data analysis. The disagreement stemmed from a clause the Pentagon wanted removed, which Anthropic feared could enable mass surveillance. The department had threatened to label Anthropic a supply‑chain risk and cancel its existing agreement, a move that previously led to a presidential directive to halt the use of its technology. Both parties are now working to resolve the language issue and preserve the partnership.Lire la suite

Anthropic chief executive Dario Amodei is back at the negotiating table with the U.S. Department of Defense after talks collapsed over the Pentagon’s demand for unrestricted access to the company’s Claude AI models. The renewed discussions aim to prevent a supply‑chain‑risk designation that could bar Anthropic from future defense work. The dispute centers on the department’s push for open‑use language and Anthropic’s refusal to compromise on two red lines: prohibiting mass surveillance of Americans and banning lethal autonomous weapons without human oversight.Lire la suite
