Several developers said they received DeepSeek upgrade emails on June 29 stating
the V4 production release will go live mid‑July and introduce peak–off‑peak API
pricing. V4 Pro and V4 Flash off‑peak rates remain unchanged; peak‑hour rates
will be twice normal levels. Peak hours are 09:00–12:00 and 14:00–18:00 daily.
Peak V4 Pro rates: cache‑hit input 0.05 yuan/MLN tokens, cache‑miss input 6
yuan/MLN tokens, output 12 yuan/MLN tokens. Peak V4 Flash rates: cache‑hit input
0.04 yuan/MLN tokens, cache-miss input 2 yuan/MLN tokens, output 4 yuan/MLN
tokens.
