DeepSeek R1 Distill Qwen 1.5B

NVIDIA
DeepSeek R1 Distill Qwen 1.5B is a lightweight dense reasoning-focused language model developed by DeepSeek AI through distillation from the larger DeepSeek R1 model. It features a 1.5B parameter transformer architecture with 28 layers, 12 attention heads, and a 1,536 hidden size, built on the Qwen 2.5 architecture and fine-tuned using reasoning traces generated by DeepSeek R1. The model transfers core reasoning behaviors into a compact efficient model optimized for mathematics, coding, and logical analysis, supporting a 128K token context window for extended reasoning tasks.
