## GPT-4 vs GPT-3.5
Aider supports
`gpt-4`,
`gpt-4-32k`,
`gpt-3.5-turbo`
and the the brand new `gpt-3.5-turbo-16k` model.
You will probably get the best results with GPT-4,
because of its large context window and
greater competance at coding
which will allow you to edit larger codebases.
Aider supports all of OpenAI's chat models, including
the the brand new `gpt-3.5-turbo-16k` model.
To use `gpt-3.5-turbo-16k`, install from GitHub per the instructions below and launch with `aider -3`.
The GPT-3.5 models are limited to editing somewhat smaller codebases.
They are less able to follow instructions for
returning code edits in a compact format,
so aider has
You will probably get the best results with one of the GPT-4 models,
because of their large context windows,
adherance to system prompt instructions and
greater competance at coding tasks.
The GPT-4 models are also able to use a
[repository map](https://aider.chat/docs/ctags.html)
to improve their ability to make changes in larger codebases.
The GPT-3.5 models are supported more experimentally
and are limited to editing somewhat smaller codebases.
They are less able to follow instructions and
aren't able to return code edits in a compact format.
So aider has
to ask GPT-3.5 to return a full copy of any code that needs to be edited.
This rapidly uses up the context window.
This rapidly uses up tokens and can hit the limits of the context window.
In practice, this means you can only use `gpt-3.5-turbo` to edit files that are
smaller than about 2k tokens (8k bytes).
The new `gpt-3.5-turbo-16k` model should be able to edit code up to 8k tokens (32k bytes).
Aider disables the
[repository map feature](https://aider.chat/docs/ctags.html)
when used with either of the GPT-3.5 models.
when used with GPT-3.5 models.
The `gpt-3.5-turbo` context window is too small to include a repo map.
Evaluation is needed to determine if `gpt-3.5-turbo-16k` can make use of a repo map.
To use `gpt-3.5-turbo-16k`, install from GitHub per the instructions below and launch with `aider -3`.
For now, aider just treats `gpt-3.5-turbo-16k` like the original `gpt-3.5-turbo` with a larger
context window.
Evaluation is still needed to determine if `gpt-3.5-turbo-16k` can make use of a repo map.
