DeepSeek Flash (officially DeepSeek-V4-Flash, "0731" build) is an open-source language model from DeepSeek positioned as the cost-efficient variant of the DeepSeek-V4 model family. It uses a Mixture-of-Experts architecture with 284 billion total parameters, of which 13 billion are activated per token, and supports a 1-million-token context window. The official version released on July 31, 2026 substantially improves agentic and coding capabilities over the April preview through extensive post-training, without changing the underlying architecture.
