DeepSeek-V4-Pro, released April 2026, is DeepSeek's flagship 1.6-trillion-parameter sparse MoE with 49 billion active parameters per token and a one-million-token context window. It pairs Compressed Sparse Attention (CSA) and Heavily Compressed Attention (HCA), using roughly 27% of V3.2's single-token inference FLOPs to make million-token context practical for frontier reasoning and agentic systems. The model supports both thinking and non-thinking modes and a dedicated XML-based tool-call schema, and DeepSeek reports strong agentic results including 80.6 on SWE-bench Verified, positioning it to rival the strongest closed-source models on coding and software-engineering tasks while staying open-weight. Open-sourced under an MIT license with weights on Hugging Face, V4-Pro is built for frontier research, multi-agent systems, and teams that want state-of-the-art reasoning with genuine long-context capability without proprietary lock-in.
