completion_ids 生成的途径

[lsm2842035890]

直接输入input_ids给model得到logits进而得到completion_ids vs 输入input_ids给model.diffusion_generate多步生成completion_ids
这两种方式对grpo训练有什么影响吗，选择后者的原因是什么~

For diffusion models, if you only sample once, the sampling sequence would be very in-accurate. That's why we need to call diffusion_generate.
