In OpenZeka's measurement, Muse-Spark-Open-816B-A42B (816B parameters), served in NVFP4 format with vLLM and speculative decoding on DGX B300 (TP=4), reached a generation speed of 306.7 tok/s per request and a time to first token (TTFT) of 46 ms with a single request.
Considering the speed targets and the available KV cache capacity, the estimated capacity is 128 users for chat use and 48 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.
