- 发生了什么
- Fireworks AI found that numerical mismatches between training and inference engines can collapse reinforcement learning reward, especially in mixture-of-experts models.
- 为何重要
- Engineers scaling RL training should care when using separate inference engines for rollout generation, as implementation differences can silently break learning.
- 注意
- Numerical discrepancies can mimic data, reward, or learning rate problems, causing expensive experimental runs that miss the root cause without proper validation.
