🚀 Policy gradient methods like DeepSeek’s GRPO are great for finetuning LLMs via RLHF. But what happens when we swap autoregressive generation for discrete diffusion, a rising architecture promising faster & more controllable LLMs? Introducing SEPO ! 📑

As an AC/SAC for too many conferences right now, I highly recommend people in these roles to gently nudge reviewers who don't reply after author rebuttal. People can be forgetful, or have busy lives but will often reply / update their scores when reminded to.
