DeepSeek V4 Pro is a large-scale Mixture-of-Experts model with 1.6T total parameters and 49B activated parameters, supporting a 1M-token context window. Designed for advanced reasoning, coding, and long-horizon agent workflows, with strong performance across knowledge, math, and software engineering benchmarks. Built on the same architecture as V4 Flash, it introduces a hybrid attention system for efficient long-context processing and supports multiple reasoning modes.
