LMArena 搞了个 Agent 竞技场排行榜，想知道哪家模型干活的实力强，去 arena.ai 看排名就行。
LMArena 在 X 上发文，指向 arena.ai/leaderboard/ag… 的 Agent Arena 榜单页面。该榜单用于对各家的 Agent 表现进行排名。具体上榜模型和评测细节需查看榜单页面。

LMArena 的 Agent Arena 榜单上新了，能看到各智能体模型在不同任务间的取舍对比，选模型前可以先去比一比。

For hour-long agent workloads, the cheapest model is not automatically the right one: Claude Opus 5.5 scores higher but costs twice as much per hour as Gemini 4 Carbon. Teams running long-horizon agents can use these per-hour cost and time figures to match model choice to budget and quality needs. The 55-minute spread among frontier models also suggests task duration, not just accuracy, should enter model selection criteria.
Agent Arena 拆了成本维度看模型：贵任务上 OpenAI 和 Anthropic 不再通吃，Gemini 4 Argon 和小米 MiMo 顶上，选型前值得对号入座。
Agent Arena 拿 5 家实验室的旗舰模型跑了长任务对比，Claude Opus 5.5 能连续干近 2 小时，Kimi 最快但也最短，差距挺直观。
