amd / ReasonLite-0.6B
Model's Last Updated: January 22 2026
Introduction of ReasonLite-0.6B
Model Details of ReasonLite-0.6B
ReasonLite is an ultra-lightweight math reasoning model. With only 0.6B parameters, it leverages high-quality data distillation to achieve performance comparable to models over 10× its size, such as Qwen3-8B, reaching 75.2 on AIME24 and extending the scaling law of small models.
- 🔥 Best-performing 0.6B reasoning model
- 🔓 Fully open-source — weights, scripts, datasets, synthesis pipeline
- ⚙️ Distilled in two stages for both efficiency and high performance
🚀 Model
The model is trained in two progressive distillation stages . First, short-CoT data is used to distill Qwen3-0.6B into AMD-0.6B-Turbo , improving AIME24 accuracy from 11.0 → 57.1 . Then, long-CoT data is used to obtain AMD-0.6B , further boosting accuracy to 75.2 .
