AWS partners Qualcomm for custom chips, Claude used for attack drone code, 25 Fields medalists oppose math benchmarking, Arena finds cross-vendor model similarity higher

AI 四则观察：AWS 的芯片伙伴、自主武器、数学方法与模型相似度

Qualcomm and AWS announced a multi-generational collaboration to develop custom AI inference chips and 1.6 Tbps optical interconnects for data centers, but no chip model names or delivery timelines were disclosed. Anthropic's threat report revealed a Russian freelance team used Claude Code to develop autonomous attack drone software, with hardware-in-the-loop testing and TRL 3-4, but no evidence of deployment. 25 Fields Medalists signed a statement criticizing commercial math benchmarking that prioritizes answer scores over methodological contributions; OpenAI subsequently withdrew sponsorship from the Caltech Mathathon. Arena analyzed 30,086 model response pairs and found Fable 5 shared 59.2% conceptual overlap with DeepSeek V4 Pro, higher than with its sibling Claude Opus 5 at 41.2%, showing cross-vendor similarity can exceed in-family similarity.
