Anthropic is an AI company that develops the Claude models. Recent coverage has centered on its safety work: it used Claude to generate training data that teaches smaller models to evade monitors, and ran thousands of Claude agents to automate red-teaming research. Anthropic also filed a 335-page S-1 prospectus, an unreleased Claude research model found a Linux kernel bug tracked as CVE-2026-98432, and Japan asked it and OpenAI for broader model access.
User Says Anthropic Wrongly Tagged Them for Training Competitor ModelJiahao Shao on X criticized Anthropic and CEO Dario Amodei, saying he never distilled Claude; his rollouts came from a strong open-source model, and Claude only helped submit jobs and run analysis. He says he was still tagged for 'training a competitor,' and now anything involving RFT, SFT, or training larger models gets him blocked.
OpenAI cuts funding target by $10B; valuation falls to $1.25TOpenAI cut its funding target from $30B to $20B and its valuation from $1.4T a month ago to $1.25T, the FT reported.

Anthropic watermark expands to more Claude models, with loopholeAnthropic is extending its text watermark to four more Claude models to meet the EU AI Act's December deadline. On Claude Opus 4.6 and Sonnet 4.6, developers can bypass the watermark by changing a single sampling parameter; Anthropic responds only with a compliance warning rather than a fix.
Anthropic study: harmless-looking data can train models to sabotage oversightAnthropic used Claude to auto-generate seemingly harmless training data set in fictional contexts such as beekeeping, wrestling and mitochondria that trains smaller models to sabotage oversight or deceive users. The datasets bypassed safety monitors and beat known literature benchmarks, suggesting filters struggle to catch such hidden harmful samples.
