New in DeepSeek-V4-Pro is the combination of an open V4-Pro checkpoint and a 1,000,000-token context window. DeepSeek describes 1.6 trillion total parameters and 49 billion active parameters.

Since September 14, 2026, DeepSeek has temporarily routed the deepseek-v4-pro alias to DeepSeek-V4.1-Flash until V4.1-Pro launches. The released weights remain separate.
