Unique: Extracts token-level confidence scores directly from the model's softmax distribution during decoding, enabling fine-grained uncertainty quantification without additional inference passes. Scores are computed end-to-end within the transcription pipeline.

vs others: Faster than ensemble-based uncertainty methods (e.g., multiple model runs) because confidence is computed in a single pass; however, less reliable than Bayesian approaches or ensemble methods because single-model confidence scores are poorly calibrated and do not account for systematic model errors.
