# Text generation web UI

A gradio web UI for running Large Language Models like LLaMA, llama.cpp, GPT-J, Pythia, OPT, and GALACTICA.

Its goal is to become the [AUTOMATIC1111/stable-diffusion-webui](https://github.com/AUTOMATIC1111/stable-diffusion-webui) of text generation.

## Installation

### One-click installers

[oobabooga-windows.zip](https://github.com/oobabooga/text-generation-webui/releases/download/installers/oobabooga-windows.zip)

Just download the zip above, extract it, and double click on "install". The web UI and all its dependencies will be installed in the same folder.

* To download a model, double click on "download-model"
* To start the web UI, double click on "start-webui" 

Source codes: https://github.com/oobabooga/one-click-installers

> **Note**
> 
> Thanks to [@jllllll](https://github.com/jllllll) and [@ClayShoaf](https://github.com/ClayShoaf), the Windows 1-click installer now sets up 8-bit and 4-bit requirements out of the box. No additional installation steps are necessary.

> **Note**
> 
> There is no need to run the installer as admin.

### Manual installation using Conda

Recommended if you have some experience with the command-line.

On Windows, I additionally recommend carrying out the installation on WSL instead of the base system: [WSL installation guide](https://github.com/oobabooga/text-generation-webui/wiki/WSL-installation-guide).

#### 0. Install Conda

https://docs.conda.io/en/latest/miniconda.html

On Linux or WSL, it can be automatically installed with these two commands:

```
curl -sL "https://repo.anaconda.com/miniconda/Miniconda3-latest-Linux-x86_64.sh" > "Miniconda3.sh"
bash Miniconda3.sh
```
Source: https://educe-ubc.github.io/conda.html

#### 0.1 (Ubuntu/WSL) Install build tools

```
sudo apt install build-essential
```


#### 1. Create a new conda environment

```
conda create -n textgen python=3.10.9
conda activate textgen
```

#### 2. Install Pytorch

| System | GPU | Command |
|--------|---------|---------|
| Linux/WSL | NVIDIA | `pip3 install torch torchvision torchaudio` |
| Linux | AMD | `pip3 install torch torchvision torchaudio --index-url https://download.pytorch.org/whl/rocm5.4.2` |
| MacOS + MPS (untested) | Any | `pip3 install torch torchvision torchaudio` |

The up to date commands can be found here: https://pytorch.org/get-started/locally/. 

#### 2.1 Special instructions

* MacOS users: https://github.com/oobabooga/text-generation-webui/pull/393
* AMD users: https://rentry.org/eq3hg

#### 3. Install the web UI

```
git clone https://github.com/oobabooga/text-generation-webui
cd text-generation-webui
pip install -r requirements.txt
```

### Alternative: manual Windows installation

As an alternative to the recommended WSL method, you can install the web UI natively on Windows using this guide. It will be a lot harder and the performance may be slower: [Windows installation guide](https://github.com/oobabooga/text-generation-webui/wiki/Windows-installation-guide).

### Alternative: Docker

```
cp .env.example .env
docker compose up --build
```

Make sure to edit `.env.example` and set the appropriate CUDA version for your GPU, which can be found on [developer.nvidia.com](https://developer.nvidia.com/cuda-gpus).

You need to have docker compose v2.17 or higher installed in your system. For installation instructions, see [Docker compose installation](https://github.com/oobabooga/text-generation-webui/wiki/Docker-compose-installation).

### Updating the requirements

From time to time, the `requirements.txt` changes. To update, use this command:

```
conda activate textgen
cd text-generation-webui
pip install -r requirements.txt --upgrade
```
## Downloading models

Models should be placed inside the `models` folder.

[Hugging Face](https://huggingface.co/models?pipeline_tag=text-generation&sort=downloads) is the main place to download models. These are some examples:

* [Pythia](https://huggingface.co/models?sort=downloads&search=eleutherai%2Fpythia+deduped)
* [OPT](https://huggingface.co/models?search=facebook/opt)
* [GALACTICA](https://huggingface.co/models?search=facebook/galactica)
* [GPT-J 6B](https://huggingface.co/EleutherAI/gpt-j-6B/tree/main)

You can automatically download a model from HF using the script `download-model.py`:

    python download-model.py organization/model

For example:

    python download-model.py facebook/opt-1.3b

If you want to download a model manually, note that all you need are the json, txt, and pytorch\*.bin (or model*.safetensors) files. The remaining files are not necessary.

#### GPT-4chan

[GPT-4chan](https://huggingface.co/ykilcher/gpt-4chan) has been shut down from Hugging Face, so you need to download it elsewhere. You have two options:

* Torrent: [16-bit](https://archive.org/details/gpt4chan_model_float16) / [32-bit](https://archive.org/details/gpt4chan_model)
* Direct download: [16-bit](https://theswissbay.ch/pdf/_notpdf_/gpt4chan_model_float16/) / [32-bit](https://theswissbay.ch/pdf/_notpdf_/gpt4chan_model/)

The 32-bit version is only relevant if you intend to run the model in CPU mode. Otherwise, you should use the 16-bit version.

After downloading the model, follow these steps:

1. Place the files under `models/gpt4chan_model_float16` or `models/gpt4chan_model`.
2. Place GPT-J 6B's config.json file in that same folder: [config.json](https://huggingface.co/EleutherAI/gpt-j-6B/raw/main/config.json).
3. Download GPT-J 6B's tokenizer files (they will be automatically detected when you attempt to load GPT-4chan):

```
python download-model.py EleutherAI/gpt-j-6B --text-only
```

## Starting the web UI

    conda activate textgen
    cd text-generation-webui
    python server.py

Then browse to 

`http://localhost:7860/?__theme=dark`

Optionally, you can use the following command-line flags:

#### Basic settings

| `--notebook`                               | Launch the web UI in notebook mode, where the output is written to the same text box as the input. |
| `--chat`                                   | Launch the web UI in chat mode. |
| `--model MODEL`                            | Name of the model to load by default. |
| `--lora LORA`                              | Name of the LoRA to apply to the model by default. |
| `--model-dir MODEL_DIR`                    | Path to directory with all the models. |
| `--lora-dir LORA_DIR`                      | Path to directory with all the loras. |
| `--model-menu`                             | Show a model menu in the terminal when the web UI is first launched. |

| `--settings SETTINGS_FILE`                 | Load the default interface settings from this json file. See `settings-template.json` for an example. If you create a file called `settings.json`, this file will be loaded by default without the need to use the `--settings` flag. |
| `--extensions EXTENSIONS [EXTENSIONS ...]` | The list of extensions to load. If you want to load more than one extension, write the names separated by spaces. |
| `--verbose`                                | Print the prompts to the terminal. |

Out of memory errors? [Check the low VRAM guide](https://github.com/oobabooga/text-generation-webui/wiki/Low-VRAM-guide).

## Presets

Inference settings presets can be created under `presets/` as text files. These files are detected automatically at startup.

By default, 10 presets by NovelAI and KoboldAI are included. These were selected out of a sample of 43 presets after applying a K-Means clustering algorithm and selecting the elements closest to the average of each cluster.
