Further evidence suggests the official release of DeepSeek V4 Flash is imminent. DeepSeek added a new Responses API page to its docs today, which currently only supports V4 Flash, while V4 Pro is not yet supported.
This aligns with the LMArena observation where only V4 Flash Thinking's knowledge cutoff was updated, confirming the grayscale testing of the model.
