A new paper introduces MarginGate, a method to ensure reproducible decoding for large language models even when using the faster BF16 format. This addresses a subtle bug where the order of requests in a batch can cause different tokens to be emitted for the same prompt. MarginGate achieves reproducibility by selectively re-checking only the low-margin decoding steps, which are prone to numerical inaccuracies, thus minimizing performance overhead compared to always using more precise FP32 verification.
