Open the original- What it measures
- The entry adds that, more informally, the term means any Transformer-based language model, and it names Gemini and GPT as examples.
- What it does not show
- The glossary does not give a threshold for 'very high', so the definition is relative and changes as models grow. It describes the term, not the quality of any particular model.
