FastCuRL Overview
2025-05-23
We release FastCuRL-1.5B-V3 and FastCuRL-1.5B-V2.
2025-03-17
We release FastCuRL-1.5B-Preview, a slow-thinking reasoning model that outperforms the previous SoTA DeepScaleR-1.5B-Preview with 50% training steps! We adapt a novel curriculum-guided iterative lengthening reinforcement learning to the DeepSeek-R1-Distill-Qwen-1.5B and observe continuous performance improvement as training steps increase. To better reproduce our work and advance research progress, we open-source our code, model, and data.

Training Data
Following DeepScaleR, our training dataset consists of 40,315 unique problem-answer pairs compiled from:
- AIME problems (1984-2023)
- AMC problems (before 2023)
- Omni-MATH dataset
- Still dataset
Acknowledgements
- Our training experiments are powered by our heavily modified fork of verl and deepscaler.
- Our model is trained on top of
DeepSeek-R1-Distill-Qwen-1.5B.
