Train a Qwen2-Level Model on RTX 5090 for Under $5090

Puro-2B introduces a fully open recipe enabling the training of a Qwen2-1.5B-level LLM on a single RTX 5090 GPU for under $5090. This initiative aims to lower the barrier for controlled training experiments amid rising costs. The post also references an arXiv paper finding that standard learning rate decay wastes high-quality data in curriculum-based pretraining, suggesting moderate decay or model averaging as solutions.
