In OpenZeka's measurement, MiniMax-M2.5 (229B parameters), served in FP8 format with vLLM on DGX B300 (TP=2), reached a generation speed of 66.8 tok/s per request and a time to first token (TTFT) of 169 ms with a single request.
Considering the speed targets and the available KV cache capacity, the estimated capacity is 126 users for chat use and 31 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.
