DeepSeek-V4.1-Flash 登顶 Agent Arena 开源模型第一
DeepSeek 这版 Flash 模型在 Agent Arena 拿下开源第一，跑任务成本只有 GPT-6.1 Sol 的四分之一左右，写网页还追平了闭源大模型，做智能体的可以看看。
DeepSeek-V4.1-Flash-20261017 (Max) 在 Agent Arena 上成为排名第一的开源模型，总榜第 11 名，基于超过 7500 次真实任务会话，净提升 5.1%。在 Confirmed Success 指标上提升 11.5%，位列第 8，且无 Tool Hallucination 问题。每次任务中位成本 0.20 美元，约为 GPT-6.1 Sol 成本的 27%。在 Code Arena: WebDev 上也以 1670 分成为第一开源模型，超过 Kimi K3 (Max)，与 GPT-6 Sol (Max) 相差约 10 分。
Big news: DeepSeek-V4.1-Flash-20261017 (Max) by @deepseek_ai is now the #1 open model in Agent Arena! It just landed at #11 overall with +5.1% net improvement across +7.5K real-world sessions. This performance also reshapes the Agent Arena Pareto frontier! All models above V4.1-Flash 20261017 in performance are proprietary at much higher cost. At $0.20 median cost per task, that’s ~37% of GPT-6.1 Sol’s improvement for about 27% of the cost. By signal, this release achieves: - #8 in Confirmed Success with +11.5% ( #1 open) - #11 in Praise vs. Complaint with +5.9% ( #1 open) - #12 in Bash Reliability with +5.4% ( #1 open) - #13 in Steerability with +2.5% ( #1 open) - No issues with Tool Hallucination Find more info on signals at the link in thread on Agent Arena. Congrats to the @deepseek_ai team on this release!
