MiniMaxH3Scheduler.set_timesteps(N) builds an N-point sigma grid ending at 0 and runs N-1 transformer forwards (the base model's '50 steps' preset is 49 forwards). The student was distilled on a 4-FORWARD grid (t = 1000/750/500/250 -> 0 on the shift-12 schedule), so --steps 4 was silently running a 3-forward, off-distribution grid. Default is now 5 grid points = the distilled 4-forward grid, with the convention documented on the flag. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
