The Big LLM Architecture Comparison

This article provides an in-depth technical comparison of LLM architectures from models like DeepSeek V3, Llama 4, Gemma 3, and Qwen3. It examines key architectural innovations including attention mechanisms, normalization techniques, mixture-of-experts designs, and efficiency improvements, analyzing how these structural changes define modern language models beyond just performance metrics.
