Research Paper Overview
InfiR2: A Comprehensive FP8 Training Recipe for Reasoning-Enhanced Language Models
Summary
This paper presents an end-to-end FP8 training recipe integrating continual pre-training and supervised fine-tuning for large language models. It uses a fine-grained, hybrid-granularity quantization strategy to maintain numerical fidelity while improving computational efficiency. Experiments on a 160B-token corpus show stable, lossless performance comparable to BF16 baselines with up to 22% faster training, 14% less memory usage, and 19% higher throughput, establishing FP8 as a practical alternative for large-scale model training.
