Why it matters
Offers a way to detect personality drift during conversation or and to flag training data that causes it, usable on models like Qwen and Llama.
Terms in this piece · Glossary
- hallucination — When a model states something false with full confidence — inventing facts, citations, or APIs that don't exist.
- fine-tuning — Taking a trained model and training it a bit more on your own examples so it gets better at one specific job.
- open weights — A model whose trained parameters are published for anyone to download and run — unlike API-only models you can access but never possess.
