MiniMax H3 Raises Shape Mismatch Error with Audio Reference Input
Ok-Flatworm5070 · reddit · 2026-08-29
A user encountered a RuntimeError: shape mismatch when using MiniMax H3 with audio files (mp3, wav) as reference input. The error indicates that a value tensor of shape [412, 32] cannot be broadcast to the target shape [486, 32]. The post includes the user's prompt configuration defining the reference audio for a documentary host video, but the cause of the dimensional mismatch remains unclear.
