Ethan Mollick revisits the GPT-4 era: no secret method, and no LLM ceiling
emollick · x · 2026-11-01
Ethan Mollick quotes his own year-old question — whether OpenAI had a secret method behind GPT-4 or whether LLMs had hit a ceiling — and answers "no" to both. He notes that less than three years ago GPT-4 was the best model in the world for a full year, and the industry widely speculated it might be as good as LLMs would ever get. Subsequent model releases disproved both the secret-sauce theory and the ceiling theory.
