My Workflow for Understanding LLM Architectures

This article by Sebastian Raschka outlines a manual workflow for understanding the architecture of new open-weight large language models (LLMs). It explains how to start with official technical reports, then inspect config files and reference implementations from the Hugging Face Model Hub and Python transformers library. The focus is on open-weight models, not proprietary ones like ChatGPT or Claude. The process is intentionally manual to aid learning, covering steps from config files to architecture insights.
