How to Tell If an LLM Was Really Trained From Scratch: A Reproducible Fingerprinting Method Detect whether an LLM was trained from scratch or derived from Qwen, Llama, or DeepSeek — by fingerprinting architecture, tokenizer, and weight provenance from public Hugging Face artifacts. Includes the two traps almost everyone hits.
