- forward num_gpus to from_pretrained (was dropped: multi-gpu only ever happened via sp_size) - FASTVIDEO_STUDIO_EXECUTOR_BACKEND=ray env knob so a deployment on a ray cluster can span nodes - FASTVIDEO_STUDIO_MODEL_PATHS="id=/local/dir" serves a registered model id from local weights (avoids re-downloading checkpoints already on shared fs) - accept an existing local dir as model_id in POST /api/jobs
