#+title: GPTel: A simple LLM client for Emacs
[[https://melpa.org/#/gptel][file:https://melpa.org/packages/gptel-badge.svg]]
GPTel is a simple Large Language Model chat client for Emacs, with support for multiple models and backends.

- It's async and fast, streams responses.
- Interact with LLMs from anywhere in Emacs (any buffer, shell, minibuffer, wherever)
- LLM responses are in Markdown or Org markup.
- Supports conversations and multiple independent sessions.
- Save chats as regular Markdown/Org/Text files and resume them later.
- You can go back and edit your previous prompts or LLM responses when continuing a conversation. These will be fed back to the model.
- Don't like gptel's workflow? Use it to create your own for any supported model/backend with a [[https://github.com/karthink/gptel/wiki#defining-custom-gptel-commands][simple API]].
GPTel uses Curl if available, but falls back to url-retrieve to work without external dependencies.

**** Kagi (FastGPT & Summarizer)
#+html: </summary>
Kagi's FastGPT model and the Universal Summarizer are both supported. A couple of notes:
1. Universal Summarizer: If there is a URL at point, the summarizer will summarize the contents of the URL. Otherwise the context sent to the model is the same as always: the buffer text upto point, or the contents of the region if the region is active.
2. Kagi models do not support multi-turn conversations, interactions are "one-shot". They also do not support streaming responses.
Register a backend with
#+begin_src emacs-lisp

** Usage
(This is also a [[https://www.youtube.com/watch?v=bsRnh_brggM][video demo]] showing various uses of gptel.)
|-------------------+-------------------------------------------------------------------------|
| *Command* | Description |
|-------------------+-------------------------------------------------------------------------|
| =gptel-send= | Send conversation up to =(point)=, or selection if region is active. Works anywhere in Emacs. |
| =gptel= | Create a new dedicated chat buffer. Not required to use gptel. |
| =C-u= =gptel-send= | Transient menu for preferences, input/output redirection etc. |
| =gptel-menu= | /(Same)/ |
|-------------------+-------------------------------------------------------------------------|
| =gptel-set-topic= | /(Org-mode only)/ Limit conversation context to an Org heading |
|-------------------+-------------------------------------------------------------------------|
*** In any buffer:
1. Call =M-x gptel-send= to send the text up to the cursor. The response will be inserted below. Continue the conversation by typing below the response.
2. If a region is selected, the conversation will be limited to its contents.
3. Call =M-x gptel-send= with a prefix argument to
- set chat parameters (GPT model, directives etc) for this buffer,
- to read the prompt from elsewhere or redirect the response elsewhere,
- or to replace the prompt with the response.
[[https://user-images.githubusercontent.com/8607532/230770018-9ce87644-6c17-44af-bd39-8c899303dce1.png]]
With a region selected, you can also rewrite prose or refactor code from here:
*Code*:
[[https://user-images.githubusercontent.com/8607532/230770162-1a5a496c-ee57-4a67-9c95-d45f238544ae.png]]
*Prose*:
[[https://user-images.githubusercontent.com/8607532/230770352-ee6f45a3-a083-4cf0-b13c-619f7710e9ba.png]]
*** In a dedicated chat buffer:
1. Run =M-x gptel= to start or switch to the chat buffer. It will ask you for the key if you skipped the previous step. Run it with a prefix-arg (=C-u M-x gptel=) to start a new session.
2. In the gptel buffer, send your prompt with =M-x gptel-send=, bound to =C-c RET=.
3. Set chat parameters (LLM provider, model, directives etc) for the session by calling =gptel-send= with a prefix argument (=C-u C-c RET=):
[[https://user-images.githubusercontent.com/8607532/224946059-9b918810-ab8b-46a6-b917-549d50c908f2.png]]
That's it. You can go back and edit previous prompts and responses if you want.
The default mode is =markdown-mode= if available, else =text-mode=. You can set =gptel-default-mode= to =org-mode= if desired.
**** Save and restore your chat sessions
Saving the file will save the state of the conversation as well. To resume the chat, open the file and turn on =gptel-mode= before editing the buffer.
** FAQ
#+html: <details><summary>
**** I want the window to scroll automatically as the response is inserted
#+html: </summary>
To be minimally annoying, GPTel does not move the cursor by default. Add the following to your configuration to enable auto-scrolling.
#+begin_src emacs-lisp
(add-hook 'gptel-post-stream-hook 'gptel-auto-scroll)
#+end_src
#+html: </details>
#+html: <details><summary>
**** I want the cursor to move to the next prompt after the response is inserted
#+html: </summary>
To be minimally annoying, GPTel does not move the cursor by default. Add the following to your configuration to move the cursor:
#+begin_src emacs-lisp
(add-hook 'gptel-post-response-functions 'gptel-end-of-response)
#+end_src
You can also call =gptel-end-of-response= as a command at any time.
#+html: </details>
#+html: <details><summary>
**** I want to change the formatting of the prompt and LLM response
#+html: </summary>
For dedicated chat buffers: customize =gptel-prompt-prefix-alist= and =gptel-response-prefix-alist=. You can set a different pair for each major-mode.
Anywhere in Emacs: Use =gptel-pre-response-hook= and =gptel-post-response-functions=, which see.
#+html: </details>
#+html: <details><summary>
**** I want the transient menu options to be saved so I only need to set them once
#+html: </summary>
Any model options you set are saved for the current buffer. But the redirection options in the menu are set for the next query only:
https://github.com/karthink/gptel/assets/8607532/2ecc6be9-aa52-4287-a739-ba06e1369ec2
You can make them persistent across this Emacs session by pressing ~C-x C-s~:
https://github.com/karthink/gptel/assets/8607532/b8bcb6ad-c974-41e1-9336-fdba0098a2fe
(You can also cycle through presets you've saved with ~C-x p~ and ~C-x n~.)
Now these will be enabled whenever you send a query from the transient menu. If you want to use these options without invoking the transient menu, you can use a keyboard macro:
#+begin_src emacs-lisp
;; Replace with your key to invoke the transient menu:
(keymap-global-set "<f6>" "C-u C-c <return> <return>")
#+end_src
See [[https://github.com/karthink/gptel/issues/94#issuecomment-1657093458][this comment by Tianshu Wang]] for an Elisp solution.
#+html: </details>
#+html: <details><summary>
**** I want to use gptel in a way that's not supported by =gptel-send= or the options menu
#+html: </summary>
GPTel's default usage pattern is simple, and will stay this way: Read input in any buffer and insert the response below it. Some custom behavior is possible with the transient menu (=C-u M-x gptel-send=).
For more programmable usage, gptel provides a general =gptel-request= function that accepts a custom prompt and a callback to act on the response. You can use this to build custom workflows not supported by =gptel-send=. See the documentation of =gptel-request=, and the [[https://github.com/karthink/gptel/wiki][wiki]] for examples.
#+html: </details>
#+html: <details><summary>
**** (Doom Emacs) Sending a query from the gptel menu fails because of a key conflict with Org mode
#+html: </summary>
Doom binds ~RET~ in Org mode to =+org/dwim-at-point=, which appears to conflict with gptel's transient menu bindings for some reason.
Two solutions:
- Press ~C-m~ instead of the return key.
- Change the send key from return to a key of your choice:
#+begin_src emacs-lisp
(transient-suffix-put 'gptel-menu (kbd "RET") :key "<f8>")

**** Why another LLM client?
#+html: </summary>
Other Emacs clients for LLMs prescribe the format of the interaction (a comint shell, org-babel blocks, etc). I wanted:
1. Something that is as free-form as possible: query the model using any text in any buffer, and redirect the response as required. Using a dedicated =gptel= buffer just adds some visual flair to the interaction.
2. Integration with org-mode, not using a walled-off org-babel block, but as regular text. This way the model can generate code blocks that I can run.

** COMMENT Will you add feature X?
Maybe, I'd like to experiment a bit more first. Features added since the inception of this package include
- Curl support (=gptel-use-curl=)
- Streaming responses (=gptel-stream=)
- Cancelling requests in progress (=gptel-abort=)
- General API for writing your own commands (=gptel-request=, [[https://github.com/karthink/gptel/wiki][wiki]])
- Dispatch menus using Transient (=gptel-send= with a prefix arg)
- Specifying the conversation context size
- GPT-4 support
- Response redirection (to the echo area, another buffer, etc)
- A built-in refactor/rewrite prompt
- Limiting conversation context to Org headings using properties (#58)
- Saving and restoring chats (#17)
- Support for local LLMs.
Features being considered or in the pipeline:
- Fully stateless design (#17)
** Alternatives
Other Emacs clients for LLMs include
- [[https://github.com/xenodium/chatgpt-shell][chatgpt-shell]]: comint-shell based interaction with ChatGPT. Also supports DALL-E, executable code blocks in the responses, and more.
- [[https://github.com/rksm/org-ai][org-ai]]: Interaction through special =#+begin_ai ... #+end_ai= Org-mode blocks. Also supports DALL-E, querying ChatGPT with the contents of project files, and more.
There are several more: [[https://github.com/CarlQLange/chatgpt-arcana.el][chatgpt-arcana]], [[https://github.com/MichaelBurge/leafy-mode][leafy-mode]], [[https://github.com/iwahbe/chat.el][chat.el]]
*** Extensions using GPTel
These are packages that depend on GPTel to provide additional functionality
- [[https://github.com/kamushadenes/gptel-extensions.el][gptel-extensions]]: Extra utility functions for GPTel.
- [[https://github.com/kamushadenes/ai-blog.el][ai-blog.el]]: Streamline generation of blog posts in Hugo.
** Breaking Changes
- =gptel-post-response-hook= has been renamed to =gptel-post-response-functions=, and functions in this hook are now called with two arguments: the start and end buffer positions of the response. This should make it easy to act on the response text without having to locate it first.
- Possible breakage, see #120: If streaming responses stop working for you after upgrading to v0.5, try reinstalling gptel and deleting its native comp eln cache in =native-comp-eln-load-path=.
- The user option =gptel-host= is deprecated. If the defaults don't work for you, use =gptel-make-openai= (which see) to customize server settings.
- =gptel-api-key-from-auth-source= now searches for the API key using the host address for the active LLM backend, /i.e./ "api.openai.com" when using ChatGPT. You may need to update your =~/.authinfo=.
