Code Arena 数据：10 月用 1/20 价格超越 4 月最强编码模型
这份分析把 Code Arena 半年的榜单和价格数据掰开了看：MiMo-V2.6-Flash 花 1/20 的钱就干掉了 Claude Opus 4.7。做编码应用选型的人能直接从中看出哪个价位段最划算。
LMArena 基于 Code Arena WebDev 榜单的分析显示，2025 年 12 月至 2026 年 10 月期间共上线 105 个模型，来自 24 个实验室，覆盖 44 期周榜。到 10 月，Xiaomi 的 MiMo-V2.6-Flash 以不到 1/20 的价格在得分上超过了 4 月的榜首 Claude Opus 4.7。
发布节奏明显加快：去年冬天每月约有 5 个新模型进入 Code Arena，7 月到 10 月则达到每月 12 到 14 个，几乎两天一个。2026 年 5 月至 10 月，榜单最高分爬升速度是冬季的 3 倍。价格区间也拉开差距：单次回答成本在 5 美分到 1 美元之间的模型中，10 月最佳模型对 4 月最佳模型的估计胜率达 65-80%。
对开发者而言，这意味着同样的编码任务预算在半年内能买到显著更强的能力，中低价位段竞争尤其激烈。分析全文由 Dawid Galarowicz 撰写，发布在 Arena.ai。
Beating April’s best coding model cost 20x less by October. We analyzed every model listed on Code Arena: WebDev from December 2025 to October 23, 2026: 105 models from 24 labs across 44 weekly leaderboards, plus what every answer cost from April to October. The pace of releases has stepped up. Last winter, about five new models entered Code Arena each month. From July to October, it was 12 to 14, almost one every other day. And from May to October, the top score climbed 3x faster than it did over the winter. Even though the labs are racing, it’s the users who are winning. By October, Xiaomi’s MiMo-V2.6-Flash outscored Claude Opus 4.7, April’s top model, at less than a twentieth of the price. And for answers costing between 5 cents and $1, October’s best model had an estimated 65-80% win rate against April’s best at the same price. Read more about how the AI race is speeding up, and what it means for the field, in the article by @DawidGalarowicz below.
