GRPO Multi-Environment Training

Two-environment GRPO pipeline with split configs to prevent cross-environment leaks:

• equivalence_llm_judge — FSDP v2 backend, 16 GPUs
• finance_sec_search — Megatron backend with YaRN (131K context), 64 GPUs

Qwen3-30B-A3B Production Pipeline

Full GRPO config for Qwen3-30B-A3B MoE with curriculum ordering, dynamic sampling, and context parallelism.

Rollout Scaling

Scale-independent rollout pipeline with multi-node vLLM, logical chunking, and fault-tolerant multi-seed execution via dependent_jobs.

Eval Pipeline Hardening

• DTensor v2 safetensors checkpoint conversion with .hf_metadata auto-recreation
• Separate per-environment eval output directories
• Standalone eval support (cross-session Slurm dependency handling)

Documentation

• Quick-start rewrite with per-environment stage-by-stage execution
• Dual backend guide (FSDP for demo, Megatron for production)
