GPT-4o for Writing Dialogue: What to Use Now That It’s Retired
What made GPT-4o special for writing dialogue
GPT-4o wrote dialogue that sounded like overheard conversation, not scripted lines. It understood rhythm, interruption, the way people talk around what they really mean. It knew that the best dialogue is often about what isn't said — the pauses, the deflections, the subject changes that reveal character.
The retirement removed a model with natural dialogue instincts. Newer ChatGPT defaults produce dialogue that's grammatically correct but often too clean, too on-the-nose — missing the mess and music of how people actually talk.
