 ## GPT-4 vs GPT-3.5
 
-Aider supports the `gpt-4` model and has new, experimental support for `gpt-3.5-turbo` and `gpt-4-32k`.

+Aider supports `gpt-4`, `gpt-3.5-turbo` and `gpt-4-32k`.
 You will probably get better results with GPT-4, because of its larger context window and
 greater competance at coding.
