Open-R1: Update #1 — Replicating DeepSeek R1 & Synthetic Data Generation

AI Impact Summary

Open-R1 Update #1 details the replication efforts surrounding the DeepSeek R1 model, focusing on reproducing its benchmark results and generating synthetic reasoning traces. A key finding is the significant token length of DeepSeek R1 responses, posing challenges for training with GRPO and requiring substantial GPU memory. The team is experimenting with configurations, including switching from two 8xH100 nodes to four, to optimize throughput and manage GPU cache utilization, and exploring streaming inference to stabilize GPU utilization.
