Reference mix (ours): output is 5%–15% of tokens and cache reads are 30%–80% of the input side. We pick a high cache share because coding agents re-send their context on every step. Cache writes aren't counted. Put in your own numbers below. Coding ratings: LMArena coding leaderboard, published 2026-10-15, CC-BY-4.0. A rating is about head-to-head preference on coding prompts, not about your codebase.

Each row links its official leaderboard and the date of its latest update we saw (checked 18 Oct 2026). "no public score" means the model isn't on that leaderboard; we never borrow a score from an older or preview version. Aider polyglot has no public score for either model yet, so LMArena is the only current signal here.
