DeepSeek V4 Pro is a large-scale Mixture-of-Experts model with 1.6 trillion total parameters and 49 billion active, supporting a 1M-token context window. It is designed for advanced reasoning, coding and long-horizon agent workflows, with strong results across knowledge, math and software-engineering benchmarks.

It is built on the same architecture as DeepSeek V4 Flash but introduces a hybrid attention system for efficient long-context processing. Reasoning-effort levels high and xhigh are supported, with xhigh mapping to maximum reasoning. It suits complex workloads such as full-codebase analysis, multi-step automation and large-scale information synthesis, where both capability and efficiency are critical.

Pricing is usage-based: $1.74/M in · $3.48/M out. Hormouz provides stable access to the model from inside Iran, with no foreign credit card or circumvention tooling required.
