In OpenZeka's measurement, GLM-5 (754B parameters), served in FP8 format with vLLM on DGX B300 (TP=4), reached a generation speed of 94 tok/s per request and a time to first token (TTFT) of 66 ms with a single request.
Considering the speed targets and the available KV cache capacity, the estimated capacity is 63 users for chat use and 15 for agentic use. The realistic capacity will likely fall between these two values. In scenarios dominated by coding, tool use, long workflows and multi-agent use, capacity approaches the agentic estimate; where shorter interactions, standard conversations and lighter tasks dominate, it approaches the chat estimate.
