the rest of the grid

Score is the Artificial Analysis Intelligence Index. Price is list, per million tokens. Usage is the share of tokens over the trailing seven days on OpenRouter and on the Vercel AI Gateway usage data, both licensed under CC BY 4.0; a dash means too small to call. Specs come from Vercel AI Gateway's model list and the lab's own documentation. Timing by sleds, which routes work across every lab and favours none.
