Yeah. This work is over claiming the novelty quite a bit.

Any of the Best of N papers that exploded in popularity after GRPO. Likelihood is not fundamental to the spirit of GRPO, any exploratory mechanism would work. That sequential LLMs …

You're right about the original GRPO proposal, but there are simplified variants that do just use best of K sampling. GRPO (or GRPO like approaches) for diffusion/flow matching sim…

That's fair. On the other hand, Minibatch OT (optimal transport) was one of the more fundamental advancements early on in flow matching & rectified flow models. This best of K appr…

This is just GRPO (proposed by DeepSeek), which similarly samples many plausible generations, selects the best of K, and trains that sample. Minibatch OT in flow matching also has …
