Compare

This is the batch-processing variant of GLM-5.3-Flash, Z.ai's open-weight natively multimodal mixture-of-experts model (320B total parameters, 18B active, MIT license, 1M-token context, hybrid sparse-plus-linear attention), offering the same coding and agentic capabilities at a lower cost via OpenRouter's asynchronous batch endpoint. It is best for high-volume, non-latency-sensitive coding or agent workloads where cost efficiency matters more than immediate response time.
