Description

BlockjustGRPO-fast + nemotron-lab-diffusion + AM + RL

AM integration Plan

draft PR: https://github.com/zyzhou5/RL/pull/4

**Plan **

  1. Working e2e pipeline with AM backend (based on Sajad's current design https://github.com/sajadn/diffusion_RL/commits/dllm_clean/). Planning to do the following test
    1. model loading
    2. model forward/backward
    3. loss parity (algorithm)
    4. vLLM supports
    5. 100 steps of training and compare reward
  2. Other features
    1. CP
  3. Other algorithms
    1. JustGRPO

Other things

  1. Sajad mentioned about a new design of the dLLM RL pipeline in Nemo-RL (https://docs.google.com/document/d/1HHzRpLfsRalQkqLGFe0vljZjRO7dwKaKWH43jZPxCu4/edit?tab=t.0), we will need to refactor on the AM side as well once that new design is implemented in Nemo-RL
    1. Timeline - might happen in a few weeks
  2. Check if huiying's refactor on AM + Nemo-RL will cause any issue NVIDIA-NeMo/Automodel#3614
    1. Timeline - estimated to be done by the end of September
