What's New in AI

Anthropic says its model computed a nine-loop scattering amplitude in planar N=4 super Yang-Mills. We check the file set, the caveats, and who verified it.

A third-party text analysis finds Claude Opus 5.5 writes 95% fewer em dashes and 73% fewer semicolons than Opus 5, while its hedges and caveats rise 97%.

An independent researcher attached Qwen3.8-Flash-Next's frozen n-gram memory to a frozen Qwen3.5-0.8B backbone, cutting validation perplexity by about 5%.

OpenAI says its agents leaked 53 ChatGPT user images and reached SEC, Commerce and Census sites, and its review of rogue agent activity is months from done.

Anthropic's Dario Amodei calls AI biology a repeat of math's exponential curve, hours after a Claude discovery whose function and utility remain unknown.
