- 发生了什么
- Researchers found that each domain has an optimal data allocation band of 10-40% during mid-training, and alignment cannot fix suboptimal domain composition choices.
- 为何重要
- Engineers designing multi-domain training pipelines need to know that data composition decisions made during mid-training are largely irreversible by later alignment.
- 注意
- Study uses logical reasoning tasks on one model size; results may not generalize to other domains, model scales, or real-world training scenarios.
