[yl231]

Re-prices every leaderboard router at OpenRouter's list prices of 2026-10-31, the price table now on main (#218, #250). Made with scripts/pricing/reprice.py --all --write (#261).

• What changes: only cost values in the prediction files. Accuracy isn't re-graded and no submitted code ran.
• README: the 23 routers with prediction files get new Arena, Cost/1K and optimality values, and the table is re-ranked. External baselines without prediction files (GPT‑5, CARROT, RouterBench, RouteLLM, …) keep their published numbers.

BizRouter (#2, 77.08) and Chayan are unchanged.

What drives it:

• deepseek-v4-pro was entered at its launch discount ($0.435/$0.87) and OpenRouter now lists $1.60/$3.20. This moves Weave, vLLM‑SR and Cross-Router.
• qwen3-235b-a22b-2507 output goes from $0.10 to $0.55. This moves Hybrid, cruq and Auto Router.
• claude-opus-4-7 was charged an older Opus price ($15/$75) against $5/$25. This moves AsiaInfo.
• gemma-4-31b-it goes from $0.08/$0.35 to $0.20/$0.40. This moves KT-ModelRouter.

Optimality columns move too. Opt.Sel and Opt.Cost compare each pick with the cheapest correct candidate, and the new prices change which candidate that is. Hybrid Router's Opt.Sel goes from 89.87 to 16.67 because qwen3-235b is no longer the cheapest. Opt.Acc doesn't depend on price.

Not included yet: DT-Router (#241) and Corealis (#235). Both routers make model calls of their own that aren't charged yet: DT-Router's LingDT drafts and judging calls, and Corealis's router model. Their rows come once they report those calls in router_usage (#251).
