-### I want better completions, should I use GPT-4?
+### I want better completions, should I use GPT-5?
 
-Perhaps surprisingly, the answer is no. The models that we suggest for autocomplete are trained with a highly specific prompt format, which allows them to respond to requests for completing code (see examples of these prompts [here](https://github.com/continuedev/continue/blob/main/core/autocomplete/templating/AutocompleteTemplate.ts)). Some of the best commercial models like GPT-4 or Claude are not trained with this prompt format, which means that they won't generate useful completions. Luckily, a huge model is not required for great autocomplete. Most of the state-of-the-art autocomplete models are no more than 10b parameters, and increasing beyond this does not significantly improve performance.
