Nadella: "Any firm that doesn't have this control will not remain a firm."

On Fareed Zakaria GPS July 27, Satya Nadella escalated his July 12 "pay for intelligence twice" essay into an existential claim: companies without their own model or an AI gateway routing across several won't survive as firms. His prescription is architectural, not commercial: "by keeping the harness separate from the model and the context and memory separate from the model, you absolutely can use multiple models," with every prompt's metadata retained locally "so that you could use all of that to train perhaps your own weights or your own open model." Note the target. He's warning specifically against proprietary coding tools from the frontier labs, which is a direct shot at Claude Code and Codex lock-in. I use Claude Code every day in my personal projects and I think he's half right: the harness/model separation is correct engineering advice regardless of who's giving it. (TechCrunch)
