Gemma-4-31B-it (31B parameters), served in BF16 format with vLLM on RTX PRO 6000, starts answering a single camera that sends one 720p image after 0.24 s, then writes 24.7 tok/s.
With 5 images per camera at 720p, the answer starts after 0.7 s. With one 2K image, after 0.32 s.
At the default target of an answer starting within 3 s (720p, one image per camera), it keeps up with at least 16 cameras at once: it still met the target at the highest number measured, so the real limit is higher.
