deepseek v4

DeepSeek-V4 is a next-generation open model designed for the million-token era. With native 1M context length, it unlocks entirely new possibilities in long-document reasoning, agent workflows, and high-complexity problem solving.

Available in two versions — **V4-Pro** and **V4-Flash** — it balances state-of-the-art performance with cost-efficiency. From advanced coding agents to deep knowledge reasoning, DeepSeek-V4 delivers top-tier capabilities across open and proprietary model benchmarks.

Powered by a novel sparse attention architecture, DeepSeek-V4 dramatically reduces compute and memory overhead while scaling context to unprecedented lengths — making ultra-long context not just possible, but practical.
