DeepSeek opened API access to DeepSeek-V4-Flash-Vision-Exp, a multimodal model that reads text and images in the same prompt. The company says it delivers performance close to Opus 4.8 and matches DeepSeek-V4-Flash on text.
Calls go through Chat Completions, Messages and Responses, the endpoint set the V4-Flash line picked up during the 0731 beta. The model sits on the DeepSeek API Platform, nine days after the V4-Pro general availability build went live on August 12, 2026.
