DeepSeek API 变更模型名称并退役 V4 Pro 等旧模型
EVENT SUMMARY
事件摘要
V4.1 Flash 通过模型名 'deepseek-flash' 调用。此前 V4 Flash 和 V4 Flash Vision Exp 已退役，暂时路由至 V4.1 Flash。V4 Pro 将于 2026 年 9 月 14 日 12:00（北京时间）起退役，所有请求路由至 V4.1 Flash 并按 Flash 价格计费。
ANALYST VIEW
中立分析
为什么重要
DeepSeek 大幅简化模型产品线，用单一 Flash 模型同时替代三个旧模型（包括更高端的 V4 Pro），表明 V4.1 Flash 性能已跨越产品层级，对行业「Flash/Pro」双层定价模式构成参考。
影响对象
所有使用 deepseek-v4-flash、deepseek-v4-flash-vision-exp 及 deepseek-v4-pro 的开发者需注意路由变更；V4 Pro 用户将在 9 月 14 日后自动切换并享受更低价格。
证据说明
来源为 DeepSeek 官方 Changelog，直接证明了模型名映射关系、退役时间点和路由策略。
不确定性
V4 Pro 退役后，当前需要 V4 Pro 级别性能的场景是否会在 V4.1 Flash 上有体验差异尚未完全验证；临时路由的持续时间未明确。
