Anthropic’s Claude AI experienced a widespread outage on Wednesday, triggering error messages for thousands of users across the Claude.ai web portal, Claude Code and the Claude API. DownDetector logged more than 4,000 reports at the peak, but by 3 p.m. PT the figure had fallen to roughly 150 as the platform recovered. Anthropic’s status page flagged “elevated errors across all models” before noting a rebound in success rates. By mid‑afternoon the service was back online, ending a day of disruption that followed earlier hiccups on Monday with the Opus 5 and Haiku 4.5 models.Leggi di più

Anthropic has introduced an Import Memory tool that lets users transfer saved context from OpenAI's ChatGPT to its Claude chatbot. The feature, now available on both web and desktop versions, simplifies the switch for people who rely on personalized prompts or past conversations. By toggling memory settings in each app and copying a generated prompt, users can move their chat history in a few minutes, with the process completing in up to 24 hours. The move comes as some users seek alternatives to ChatGPT’s recent policy shifts.Leggi di più

OpenAI announced the ChatGPT for Academic Researchers program, offering free access to its latest GPT-5.6 Sol Pro model for up to 100,000 scientists, mathematicians and engineers through 2027. The initiative starts with 10,000 participants this summer and includes hands‑on support, the ability to add four institutional collaborators, and a pledge that researchers' data will not be used to train future models. The move follows OpenAI's earlier rollout of Prism, an AI tool for scholarly work, and aligns with a $250 million commitment to external scientific research.Leggi di più

Anthropic's AI tool Mythos uncovered a new meet-in-the-middle technique that slashes the number of inputs needed to attack a three‑round version of AES from thousands to just 289. The breakthrough, which relies on a Möbius Bridge fingerprinting algorithm, could accelerate cryptanalytic attacks by 200‑ to 800‑fold against the weakened cipher. Anthropic stresses that the results stem from a reduced‑round test and that full‑strength AES remains far more resistant, but the research highlights the growing role of large language models in uncovering cryptographic weaknesses.Leggi di più

Microsoft announced a $3.2 billion gain on its $5 billion Anthropic investment while taking a $600 million charge to its OpenAI holding in its fiscal 2026 fourth‑quarter results. The boost added 33 cents to diluted earnings per share, bringing the quarter’s EPS to $4.81. The company also reported $90 billion in revenue and $35.8 billion in net income, underscoring a strong finish to the fiscal year despite the mixed performance of its two flagship AI partners.Leggi di più

Meta announced its push into enterprise artificial intelligence during its second‑quarter earnings call, with CEO Mark Zuckerberg outlining a broad strategy that goes past the company’s newly launched AI agents for customer service. He said Meta will sell APIs, business‑focused agents, and even compute capacity to large firms, turning AI into a new revenue stream alongside advertising and subscriptions. Zuckerberg acknowledged that selling to businesses requires a different sales approach, but he emphasized the long‑term potential of AI tools built for both small advertisers and bigger corporate clients.Leggi di più

Lilian Weng, co‑founder of the AI startup Thinking Machines, announced her departure this week, citing health concerns and the relentless pace of startup life. Within days, OpenAI confirmed she would rejoin the organization as head of a new top‑level research group focused on accelerating internal AI work, including recursive self‑improvement. The move underscores the fierce talent competition among AI labs and highlights Weng’s shift from a founder role to a less pressure‑filled position at a larger company.Leggi di più

Microsoft reported record earnings and used the momentum to announce a broader push into home‑grown artificial‑intelligence models. CEO Satya Nadella told analysts the company will sell its own models, agents and security tools alongside OpenAI and Anthropic offerings, emphasizing a multi‑model strategy that keeps customers’ data and harnesses separate from any single provider. The move follows a fiscal year that generated $331.8 billion in revenue and $133.7 billion in profit, and comes amid growing concerns over data leaks, vendor lock‑in and recent AI‑related security incidents.Leggi di più
