margins

OpenAI cut GPT-5.6 Luna by 80% three weeks after launch and said the cut was funded by Sol rewriting OpenAI's own production kernels. The coverage called it a blink at China. The better story is who did the optimizing — and what it means when a model becomes a line item on both sides of its own P&L.

In twelve days, Chinese labs pushed the capability floor toward zero, Anthropic halved the price of the frontier, and Google cut Flash tokens again. Read together, the fortnight says one thing: the capability premium is over, and margin is the only battleground left. A ledger of who pays.
