Batch-processing variant of DeepSeek V4.1 Flash, DeepSeek's open-weight sparse MoE model built on its Causal Encoder-Decoder architecture (8B active parameters on input, 16B on output, 1M-token context). Same coding and agentic capabilities as the standard model, offered at lower cost via asynchronous batch processing for high-volume jobs that do not need real-time responses.
