2 reports9 月 8 日，DeepSeek 发布 DeepSeek V4.1 Flash 中间版本内测通知。该模型采用新结构，具备原生多模态支持，相比正式版能力更强、速度更快且成本更低。调用方式保持不变，需将模型名设置为 deepseek-v4.1-flash-expires-on-0910，当前计费与 deepseek-v4-flash 相同，每账号限流 20 并发。此前 DeepSeek-V4-Flash 正式版 API 于 7 月底上线公测，Agent 能力大幅增强；8 月 21 日，DeepSeek-V4-Flash-Vision-Exp 多模态视觉理解模型上线，支持输入 JPEG、PNG、GIF、WebP 等格式图片进行描述、截图文字识别及图表分析。
DeepSeek 于近日开启 DeepSeek V4.1 Flash 限时内测，该版本原生支持多模态且生成速度更快、成本更低。用户接入 API 无需修改 base_url，仅需将模型名称设为 deepseek-v4.1-flash-expires-on-0910，测试期间计费标准与 V4 Flash 相同，单账号支持 20 路并发，该版本将于 9 月 10 日自动过期。官方在反馈问卷中询问用户是否认为该模型能全面替换线上 DeepSeek V4 Pro，暗示其旨在向 Pro 靠拢而非仅做提速降本。实测显示，V4.1 Flash 中文长文写作叙事节奏更自然，前端案例中科幻飞船驾驶舱 HUD 体现了 UI 与交互细节进步，但 macOS 网页操作系统制作表现中规中矩。综合来看，该版本生成速度快且稳定，若能在保持速…
