MODEL GENOME: FINGERPRINTING WHETHER AN LLM WAS TRAINED FROM SCRATCH OR DERIVED

Summary from the TLDR AI newsletter

Model Genome is a pipeline that fingerprints models on architecture, tokenizer, and weights, and combines them into a single at-a-glance genotype. It can be used to help determine whether a model is truly self-developed from scratch. Building on open-weight bases is legitimate and widespread, so the tool only reports lineage, not wrongdoing.
