Open-Sourcing GLM Training Stack: Solving RL Train-Rollout Numerical Mismatch

hsu_byron · x · 2026-08-11

Slime Framework has open-sourced its deterministic train–rollout alignment stack used for GLM-5.2-scale training.

The release tackles the persistent numerical mismatch between training and rollout in RL infrastructure. The stack includes comprehensive support for FP8 weights + FP8 KV rollout, DeepEP, DeepGEMM, and sparse attention, offering a tradeoff-free solution for production-scale alignment.
