DeepSeek V4.1-Flash 上线 DeepSeek API 并在 WorkBuddy 开放，原生支持多模态，WorkBuddy 提供两周免费试用。V4-Flash 与 V4-Flash-Vision-Exp 已退役，deepseek-v4-flash 等相关名称临时路由到 V4.1-Flash；多方差测显示 V4.1-Flash 在性能、成本、速度与总运行时间上超过 V4-Pro，V4-Pro 将逐步下线。自 2026 年 9 月 14 日 04:00 UTC 起，所有 deepseek-v4-pro 请求将按 V4.1-Flash 费率路由到 V4.1-Flash，直至 V4.1-Pro 发布；WorkBuddy（含 Codebuddy）与 opencode 等官方合作伙伴已全面支持。
推荐理由
DeepSeek 以 V4.1-Flash 取代 V4-Pro，读者可以据此了解模型迭代在性能、成本与速度之间的取舍。

⚡ V4.1-Flash is now live on the DeepSeek API with native multimodal support. Set your model to deepseek-flash. 🔹 V4-Flash & V4-Flash-Vision-Exp are retired. For compatibility, deepseek-v4-flash and deepseek-v4-flash-vision-exp temporarily route to V4.1-Flash. 🔹 Tests by multiple parties put V4.1-Flash ahead of V4-Pro on performance, cost, speed & total runtime. We’re phasing out V4-Pro. 🔹 Starting at 04:00 UTC on Sept 14, 2026, all deepseek-v4-pro requests will route to V4.1-Flash at V4.1-Flash rates.
