# ======================================================================
#  Vanilla Video Reward Pipeline — vLLM/OpenAI-compatible backend,
#  per-dimension scoring (3 dims):
#      - instruction_following
#      - visual_quality
#      - world_consistency
#  Definitions live in ../prompts/definitions.md.
#
#  For every video, the model is called once per scoring dimension and
#  asked to first reason, then assign an integer score in 1..5.
#
#  Input data: a point-wise benchmark JSON whose ``video_path`` field is
#  resolved relative to the JSON's directory.
#
#  Start a vLLM OpenAI-compatible server in another terminal first.
#
#  Usage:
#    bash infer.sh
#    bash infer.sh 50
#    bash infer.sh all 12 my_run
#    bash infer.sh all 12 my_run /path/data.json
#
#    $1 num_samples        : number of videos or 'all' (default: all)
#    $2 concurrency        : default 32
#    $3 output tag         : default infer
#    $4 data json path     : default ../data/firm-video-bench.json
#    $5 vLLM base URL      : default http://127.0.0.1:8000/v1
#    $6 served model name  : default Qwen3-VL-8B-Instruct
