# FastH3 OmniRef (Ref2VA) on one DGX Spark (GB10, unified memory): the full NVFP4 stack, one clip per prompt.
#
# Point model_path at a composed OmniRef model directory: the distilled
# transformer_ref export (with its packed nvfp4_weights.safetensors) symlinked
# together with base MiniMax-H3's text_encoder, tokenizer, processor, vae and
# audio_vae. examples/inference/basic/basic_fasth3_omniref_pdd.py builds that
# directory and runs the same stack with --profile spark.
#
# The contract in the export's fastvideo_inference.json fixes the attention
# backend, the VSA tile size and the eight-forward PDD partition; the run only
# picks the device's offload policy and its environment:
#
# GB10: everything stays resident; cuDNN mm_fp4 and the dense batched decoder.
