c43-sft-checkpoint-1004
Intermediate checkpoint, not the final model. This is the SFT-stage checkpoint that the
GRPO stage started from, released so the training pipeline can be resumed from the middle.
For inference use sjin59/c43g-s600m2.
The task: given 4 shuffled frames from a video plus a caption describing what happens,
recover the original chronological order. Output is four letters, e.g. "C,B,A,D".
