# LLM powered development for Neovim
**llm.nvim** is a plugin for all things LLM. It uses [**llm-ls**](https://github.com/huggingface/llm-ls) as a backend.
This project is influenced by [copilot.vim](https://github.com/github/copilot.vim) and [tabnine-nvim](https://github.com/codota/tabnine-nvim)
Formerly **hfcc.nvim**.

> When using the Inference API, you will probably encounter some limitations. Subscribe to the *PRO* plan to avoid getting rate limited in the free tier.

## Features
### Code completion
This plugin supports "ghost-text" code completion, à la Copilot.
### Choose your model
Requests for code generation are made via an HTTP request.
You can use the Hugging Face [Inference API](https://huggingface.co/inference-api) or your own HTTP endpoint, provided it adheres to the APIs listed in [backend](#backend).
### Always fit within the context window
The prompt sent to the model will always be sized to fit within the context window, with the number of tokens determined using [tokenizers](https://github.com/huggingface/tokenizers).
## Configuration
### Backend
**llm.nvim** can interface with multiple backends hosting models.
You can override the url of the backend with the `LLM_NVIM_URL` environment variable. If url is `nil`, it will default to the Inference API's [default url](https://github.com/huggingface/llm-ls/blob/8926969265990202e3b399955364cc090df389f4/crates/custom-types/src/llm_ls.rs#L8)
When `api_token` is set, it will be passed as a header: `Authorization: Bearer `.
#### Inference API
##### **backend = "huggingface"**
[API](https://huggingface.co/docs/api-inference/detailed_parameters#text-generation-task)
1. Create and get your API token from here https://huggingface.co/settings/tokens.
2. Define how the plugin will read your token. For this you have multiple options, in order of precedence:
1. Pass `api_token = ` in plugin opts - this is not recommended if you use a versioning tool for your configuration files
2. Set the `LLM_NVIM_HF_API_TOKEN` environment variable
3. You can define your `HF_HOME` environment variable and create a file containing your token at `$HF_HOME/token`
4. Install the [huggingface-cli](https://huggingface.co/docs/huggingface_hub/quick-start) and run `huggingface-cli login` - this will prompt you to enter your token and set it at the right path
3. Choose your model on the [Hugging Face Hub](https://huggingface.co/), and, in order of precedence, you can either:
1. Set the `LLM_NVIM_MODEL` environment variable
2. Pass `model = ` in plugin opts
Note: the `model`'s value will be appended to the url like so : `{url}/{model}` as this is how we route requests to the right model.
#### [Ollama](https://ollama.com/)
##### **backend = "ollama"**
[API](https://github.com/ollama/ollama/blob/main/docs/api.md)
Refer to Ollama's documentation on how to run ollama. Here is an example configuration:
```lua
{
model = "codellama:7b",
url = "http://localhost:11434/api/generate",
-- cf https://github.com/ollama/ollama/blob/main/docs/api.md#parameters
request_body = {
-- Modelfile options for the model you use
options = {
temperature = 0.2,
top_p = 0.95,
}
}
}
```
Note: `model`'s value will be added to the request body.
#### Open AI
##### **backend = "openai"**
Refer to Ollama's documentation on how to run ollama. Here is an example configuration:
```lua
{
model = "codellama",
url = "http://localhost:8000/v1/completions",
-- cf https://github.com/abetlen/llama-cpp-python?tab=readme-ov-file#openai-compatible-web-server
request_body = {}
}
```
Note: `model`'s value will be added to the request body.
#### [TGI](https://github.com/huggingface/text-generation-inference)
##### **backend = "tgi"**
[API](https://huggingface.github.io/text-generation-inference/#/Text%20Generation%20Inference/generate)
Refer to TGI's documentation on how to run TGI. Here is an example configuration:
```lua
{
model = "bigcode/starcoder",
url = "http://localhost:8080/generate",
-- cf https://huggingface.github.io/text-generation-inference/#/Text%20Generation%20Inference/generate
request_body = {
parameters = {
temperature = 0.2,
top_p = 0.95,
}
}
}
```
### Models
#### [Starcoder](https://huggingface.co/bigcode/starcoder)
```lua
{
tokens_to_clear = { "<|endoftext|>" },
fim = {
enabled = true,
prefix = "",
middle = "",
suffix = "",
},
model = "bigcode/starcoder",
context_window = 8192,
tokenizer = {
repository = "bigcode/starcoder",
}
}
```
> [!NOTE]
> These are the default config values
#### [CodeLlama](https://huggingface.co/codellama/CodeLlama-13b-hf)
```lua
{
tokens_to_clear = { "" },
fim = {
enabled = true,
prefix = "
",
middle = " ",
suffix = " ",
},
model = "codellama/CodeLlama-13b-hf",
context_window = 4096,
tokenizer = {
repository = "codellama/CodeLlama-13b-hf",
}
}
```
> [!NOTE]
> Spaces are important here
### [**llm-ls**](https://github.com/huggingface/llm-ls)
By default, **llm-ls** is installed by **llm.nvim** the first time it is loaded. The binary is downloaded from the [release page](https://github.com/huggingface/llm-ls/releases) and stored in:
```lua
vim.api.nvim_call_function("stdpath", { "data" }) .. "/llm_nvim/bin"
```
When developing locally, when using mason or if you built your own binary because your platform is not supported, you can set the `lsp.bin_path` setting to the path of the binary. You can also start **llm-ls** via tcp using the `--port [PORT]` option, which is useful when using a debugger.
`lsp.version` is used only when **llm.nvim** downloads **llm-ls** from the release page.
#### Mason
You can install **llm-ls** via [mason.nvim](https://github.com/williamboman/mason.nvim). To do so, run the following command:
```vim
:MasonInstall llm-ls
```
Then reference **llm-ls**'s path in your configuration:
```lua
{
-- ...
lsp = {
bin_path = vim.api.nvim_call_function("stdpath", { "data" }) .. "/mason/bin/llm-ls",
},
-- ...
}
```
### Tokenizer
**llm-ls** uses [**tokenizers**](https://github.com/huggingface/tokenizers) to make sure the prompt fits the `context_window`.
To configure it, you have a few options:
* No tokenization, **llm-ls** will count the number of characters instead:
```lua
{
tokenizer = nil,
}
```
* from a local file on your disk:
```lua
{
tokenizer = {
path = "/path/to/my/tokenizer.json"
}
}
```
* from a Hugging Face repository, **llm-ls** will attempt to download `tokenizer.json` at the root of the repository:
```lua
{
tokenizer = {
repository = "myusername/myrepo"
api_token = nil -- optional, in case the API token used for the backend is not the same
}
}
```
* from an HTTP endpoint, **llm-ls** will attempt to download a file via an HTTP GET request:
```lua
{
tokenizer = {
url = "https://my-endpoint.example.com/mytokenizer.json",
to = "/download/path/of/mytokenizer.json"
}
}
```
### Suggestion behavior
You can tune the way the suggestions behave:
- `enable_suggestions_on_startup` lets you choose to enable or disable "suggest-as-you-type" suggestions on neovim startup. You can then toggle auto suggest with `LLMToggleAutoSuggest` (see [Commands](#commands))
- `enable_suggestions_on_files` lets you enable suggestions only on specific files that match the pattern matching syntax you will provide. It can either be a string or a list of strings, for example:
- to match on all types of buffers: `enable_suggestions_on_files: "*"`
- to match on all files in `my_project/`: `enable_suggestions_on_files: "/path/to/my_project/*"`
- to match on all python and rust files: `enable_suggestions_on_files: { "*.py", "*.rs" }`
### Commands
**llm.nvim** provides the following commands:
- `LLMToggleAutoSuggest` enables/disables automatic "suggest-as-you-type" suggestions
- `LLMSuggestion` is used to manually request a suggestion
### Package manager
#### Using [packer](https://github.com/wbthomason/packer.nvim)
```lua
require("packer").startup(function(use)
use {
'huggingface/llm.nvim',
config = function()
require('llm').setup({
-- cf Setup
})
end
}
end)
```

```lua
require("lazy").setup({
{
'huggingface/llm.nvim',
opts = {
-- cf Setup
}
},
})
```
#### Using [vim-plug](https://github.com/junegunn/vim-plug)
```vim
Plug 'huggingface/llm.nvim'
