Qwen3-VL-4B-Instruct (4.4B parameters), served in FP8 format with vLLM on Jetson Orin NX 16GB, starts answering a single camera that sends one 720p image after 1.67 s, then writes 14.2 tok/s.
With 3 images per camera at 720p, the answer starts after 4 s. With one 1080p image, after 4.34 s.
At the default target of an answer starting within 3 s (720p, one image per camera), it keeps up with 2 cameras at once.
