DeepSeek V4 Flash gains vision: multimodal agent performance nears Opus 4.8

haider1 · x · 2026-08-21

DeepSeek officially launched the experimental multimodal model DeepSeek-V4-Flash-Vision-Exp, available via API as model='deepseek-v4-flash-vision-exp'. It matches V4-Flash on text (agents, reasoning, world knowledge) while making a major leap on multimodal agent benchmarks, closing in on Opus-4.8. DeepSeek Harness 0.1.1 shipped the same day with out-of-the-box support.

The retweeter's testing found it even stronger than the 0731 build on tasks that have nothing to do with vision.
