DeepSeek V4 Flash Vision Exp as a Labs experiment, open for a short test window: temporary, not a permanent id. DeepSeek's first multimodal V4 model, served from the official DeepSeek-V4-Flash-Vision-Exp open weights: the fast agentic coding MoE (284B total, 13B active) with native image understanding, on a 1M-token context. Reasoning has four modes: non-think (none), think low (low, the default), think high (high) and think max (max). Access is seat-gated through the Labs page while an experiment is live. It is offered at limited capacity and low availability, so expect it to be flaky and to go down under load: crash it, give it a moment, and try again. For production work we recommend umans-coder or umans-deepseek-v4-pro-0813.
