Navigate logical layers of code changes, visualize relationships, and explore their blast radius. 📝 WalkthroughWalkthroughAutomodel adds options for LoRA, shuffling, packing, activation checkpointing, MTP, backend kernels, and pipeline parallelism. DPO and GRPO add optimizer, environment, rollout, parallelizer, and W&B result-table options. ChangesAutomodel configuration flow
DPO and GRPO training configuration
Suggested reviewers: Priority: ➖ Normal Change: Feature Merge Risk: 🟡 Moderate · up to Several newly exposed training options do not behave as documented. Choosing a custom optimizer such as TE FusedAdam can fail before training starts. A MoE job can disable a safeguard and hit backward failures. Requested W&B result tables can be silently dropped. The memory-efficient LoRA setting has no effect. Packing and shuffle settings are not fully honored. Resolve these before merging. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)
