Balance- · reddit · 2026-10-30
NVIDIA released AlpaJudge on Hugging Face, a family of learned judge models for evaluating autonomous-driving reasoning, with weights under OpenMDW-1.1 and code under Apache 2.0. Two variants: AlpaJudge-RB (reference-based) takes a question, reference and candidate answer to output a 0-1 alignment probability; AlpaJudge-RF (reference-free) takes front-wide/tele camera frames, ego past/future meta-actions and a candidate rationale, outputting five rubric probabilities plus aggregated action, component and overall scores.
