  "title": "TRACE: Rollout-Guided Quantization-Aware Training for FP4 Reinforcement Learning of MoE Language Models",
  "summary": "TRACE replaces independent train-side and rollout-side FP4 quantization in RL post-training with rollout-guided quantization-aware training that aligns the two quantized execution paths, plus a caching scheme that selectively stores mantissa and scale data from deeper layers. It costs additional training-time machinery: quantization-information caching and communication between rollout and training paths, implementation complexity in the RL stack, and reliance on FP4-capable hardware to realize the speedup. It can fail if the target hardware lacks native FP4 support (negating throughput gains), if the workload is inference rather than RL training (where the method does not apply), or if train-rollout discrepancy is not the accuracy bottleneck in the reader's setting.",
  "rationale": "The method targets RL post-training of large-scale MoE models on multi-GPU infrastructure with FP4 hardware, none of which the reader possesses, so it is worth tracking but not adoptable now.",
