DeepSeek V4.1 Flash is DeepSeek's open-weight sparse MoE model and the first built on the company's Causal Encoder-Decoder architecture, activating 8B parameters on input and 16B on output with a 1M-token context window. It targets coding, terminal and computer-use agents, and long-horizon multi-step tasks as a low-cost, high-throughput sibling to DeepSeek's Pro line.
