It is served behind the official API id `deepseek-v4-pro` and is distinct from catalog `deepseek-v4-pro-max`, which is the maximum reasoning-effort mode of Pro rather than this dated GA build. Same Pro MoE scale as peers (1.6T total / 49B activated). It supports low, high, and max reasoning effort, a 1M-token context window, up to 384K output tokens, and DeepSeek's OpenAI-compatible Chat Completions and Responses APIs. GA open weights are on Hugging Face at `deepseek-ai/DeepSeek-V4-Pro-0813` (MIT), distinct from the April preview repo `deepseek-ai/DeepSeek-V4-Pro`. New time-of-day pricing takes effect August 16: peak rates are $0.044 cached input, $1.32 uncached input, and $3.96 output per million tokens; off-peak rates are half those amounts.
