DeepSeek-V4-Pro: Million-Token Context MoE Model
DeepSeek-V4-Pro, developed by DeepSeek-AI, is a powerful 1.6 trillion parameter (49 billion activated) Mixture-of-Experts (MoE) language model designed for highly efficient long-context intelligence. A standout feature is its support for an impressive one million token context length, achieved through a novel hybrid attention mechanism combining Compressed Sparse Attention (CSA) and Heavily Compressed Attention (HCA). This architecture dramatically reduces inference FLOPs and KV cache requirements compared to previous versions.
