-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

-So aider has

-This rapidly uses up tokens and can hit the limits of the context window.

 Aider disables the

-The `gpt-3.5-turbo` context window is too small to include a repo map.
-Evaluation is still needed to determine if `gpt-3.5-turbo-16k` can make use of a repo map.

 In practice, this means you can use aider to edit a set of source files
 that total up to the sizes below.

 This minimizes your use of the context window, as well as costs.
