This section provides links to valuable external tutorials and resources related to multimodal AI:

Reasoning and Knowledge Distillation

• Distilling DeepSeek R1 into Qwen: A tutorial demonstrating how to distill the reasoning abilities of DeepSeek R1 (a 671B parameter MoE model) into smaller models like Qwen using the NVIDIA NeMo 2.0 Framework. The repository includes notebooks for extracting reasoning data and training models with the distilled knowledge.
