In OpenZeka's measurement, MiniMax-M3 (427B parameters), served in NVFP4 format with vLLM and speculative decoding on 4× DGX Spark (TP=4), reached a generation speed of 34.5 tok/s per request and a time to first token (TTFT) of 453 ms with a single request.
Considering the speed targets and the available KV cache capacity, the estimated capacity is 8 users for chat use and 3 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.
