DeepSeek V4 Flash is a specialized Mixture-of-Experts language model engineered to balance high-level reasoning with operational efficiency. Built with 284 billion total parameters and 13 billion activated parameters, the architecture utilizes a hybrid attention mechanism that integrates Compressed Sparse Attention and Heavily Compressed Attention. This design, further reinforced by Manifold-Constrained Hyper-Connections to improve signal propagation stability, allows the model to maintain strong performance across extensive data sequences while significantly reducing the computational overhead typically associated with large-scale context processing.

As the streamlined counterpart to the broader V4 series, this model is optimized for rapid response times and cost-effective deployment in agentic workflows and coding assistants. It inherits the reasoning capabilities of its larger counterparts, performing on par with the Pro variant on standard agent tasks while providing a more lightweight footprint. By supporting configurable reasoning efforts, the model offers a flexible tool for developers who require a balance of deep analytical power and high-throughput performance in production environments.
