Isaac-0.2-2B + SAM2 · Jetson Thor · FP16 full-generation baseline

Measurement details

Model & hardware

Isaac-0.2-2B + SAM2 · NVIDIA Jetson Thor · TensorRT backend.

Execution

Baseline: FP16 response generation completes before coordinate output. Optimized: FP8 response generation stops at coordinates; image understanding remains FP16.

Measurement

Instruction submission to completed target-coordinate output: 3.16 s → 0.30 s. This is prompt-response time, not time to first token.

Recording

The recording shows target selection, segmentation, and tracking following a text instruction.
