Experimental API-only vision variant of DeepSeek-V4-Flash-0731 (released Aug 21, 2026), adding image input (up to 600 images/request) while matching the text model on agents, reasoning, and world knowledge. Same rate card as V4-Flash: $0.44 in / $1.32 out peak, $0.22 / $0.66 off-peak, cache-hit $0.007 (per 1M). Benchmarks are DeepSeek's self-reported Harness numbers — close to but trailing Opus 4.8 on most rows (Terminal-Bench 2.1 83.9).
