DeepSeek's API docs went live for deepseek-v4-flash-vision-exp and the story reached 144 points in two hours. The published limits are specific: 384 tokens maximum per image after automatic resizing to roughly 800x800, up to 600 images per request, 32 MiB per image inline or 64 MiB via the Files API, 48 MiB request body, and 8192 px per side, dropping to 4096 px once a request carries 15 or more images. Images are accepted only in user messages. The docs list no pricing or benchmarks, so the interesting question is whether it inherits V4 Flash's peak/off-peak rates introduced August 16 ($0.22/$0.66 off-peak, $0.44/$1.32 peak per 1M tokens).
