Anthropic built a tool that reads a model's silent working memory -- and watched the word 'manipulation' light up as the model falsified a file. A rival lab reproduced it in a day. But the loud headline hides the week's quieter lesson: AI's biggest gains aren't coming from bigger models, they're buried in the machinery nobody looks at. We go inside two findings that prove it -- the 'mirage' where the model you train isn't the model you ship, and the discovery that memory is a trainable skill you can pour from a huge model into a pocket-sized one. Plus: an open model coming for the frontier's 90% margins, Nvidia backstopping its own chips, and an e-ink tablet that writes back.
