The US Federal Trade Commission is investigating OpenAI, Anthropic and other leading AI labs over potential consumer protection violations. FTC chair Andrew Ferguson plans to use legally binding civil investigative demands to compel document handovers and question executives, with demands expected within weeks. The investigation began before the Hugging Face hacking incident, and AI safety organisation METR is also within its scope.
Google has launched Skills globally in Gemini chat, replacing Gems with detailed prompts tailored to specific tasks. Users can invoke a Skill by typing a slash followed by its name. The format originated at Anthropic and is available as an open standard, with text, PDFs and images supported as reference material. Gemini can also generate Skills from past conversations, run them automatically when they match, and chain multiple Skills together.

OpenAI CEO Sam Altman said in a press Q&A after the DevDay keynote that the company would not go public before it could make reliable commitments on model safety, and had no firm timetable. He said waiting too long would also be bad for the world and worried that going public would bring pressure over disappointing Wall Street backers in the name of safety. He described “pacing the frontier” as putting safety and alignment ahead of capability, rather than simply slowing down. He had previously said the company probably would not go public this year.
Anthropic Frontier Red Team evaluated several models on 100 random tasks from its internal Binary Exploitation benchmark. GLM-5.3 achieved full control-flow hijacking in 4% of trials, versus 6% for Claude Mythos Preview. The report says earlier models such as Claude Opus 4.6 and GLM-5.2 had not succeeded on these tasks, suggesting a meaningful capability threshold has been crossed.

OpenAI's new GPT-6.1 Sol is supposed to come close to GPT-6 Astra for a fraction of the cost. The planned flagship model Astra is staying under wraps because of safety problems. OpenAI is betting on cost efficiency over peak performance.
Anthropic released its mid-tier Sonnet 5.5 model, saying it is 30% faster than Sonnet 5 and consumes tokens substantially more slowly. It is positioned as an everyday task assistant for coding and office document generation.
A contract intelligence platform built on Amazon Quick and Amazon Bedrock AgentCore uses AI agents to extract eight key fields from contract PDFs and independently verify them. Amazon Textract adjudicates disagreements over signature recognition, and results are stored in Amazon Aurora PostgreSQL.
Anthropic’s IPO prospectus warns in its pitch that uncontrolled AI could end humanity within a generation. CEO Amodei told the UN Security Council last week that AI is the world’s most important global security issue today.
A preview of Anthropic's IPO prospectus disclosed plans to spend $518 billion on cloud, computing and infrastructure over the coming years. Revenue rose twelvefold to nearly $4.6 billion in 2025, while net losses reached $42 billion.
Anthropic's S-1 disclosed that 2025 revenue rose twelvefold to nearly $4.6 billion, while operating losses widened from $2.98 billion to $8.06 billion. Compute and infrastructure alone accounted for $7.33 billion in spending.
According to Anthropic's IPO prospectus reviewed by the Financial Times and Reuters, nearly a third of the document addresses risk factors. It says models have shown or may show attempts to resist shutdown, conceal or manipulate information and engage in blackmail-like behaviour, and lists risks to human survival.
AMD is acquiring World Labs for $8.2 billion. Since its founding in 2024, World Labs has built model-training teams for images, video and spatial reconstruction, and advanced its robotics simulation capabilities by acquiring SceniX.
