* Description :unfold:
This module integrates LLMs into Emacs for analyzing or generating code and
text, powered by the [[https://github.com/karthink/gptel][gptel]] package. Out of the box, ChatGPT is the default
backend, but it can talk to other LLMs given [[*Configuration][some configuration]].

Doom exposes these keybinds for gptel's commands:

* Configuration

#+end_quote

To use this module with only ChatGPT, you only need to set ~gptel-api-key~ to your
OpenAI key. For other LLMs you'll need to call one of the ~gptel-make-*~ functions
in an ~(after! gptel ...)~ block. Examples of these calls can be found [[https://github.com/karthink/gptel?tab=readme-ov-file#other-llm-backends][in gptel's
readme]].
