DeepSeek V5
DeepSeek hasn't said a word about V5 — but the runway is being cleared. V4 Pro and V4 Flash have sat in open-weight preview since April 24, and the API's legacy deepseek-chat / deepseek-reasoner aliases retire July 24 — the cleanest signal yet that V4 goes GA, with V5 behind it. We watch the API either way: the second anything new answers, ArtificialWatch fires.

The API housecleaning: legacy aliases retire July 24
DeepSeek's docs set July 24, 15:59 UTC as the retirement of the legacy deepseek-chat and deepseek-reasoner aliases — the kind of housecleaning labs do right before a stable release. V4 GA first; V5 is the follow-through. via DeepSeek API docs

Both variants shipped to Hugging Face under MIT: V4 Pro at 1.6T parameters (MoE, ~49B active per token) and V4 Flash at 284B (~13B active). Preview status, no stable date announced. via DeepSeek · Hugging Face
