# Text generation web UI
|
|
|
|
A gradio web UI for running large language models like gpt-j-6B, gpt-neo, opt, galactica, and pygmalion on your own computer.
|
|
|
|
Its goal is to become the [AUTOMATIC1111/stable-diffusion-webui](https://github.com/AUTOMATIC1111/stable-diffusion-webui) of text generation.
|
|
|
|
**[Try it on Google Colab.](https://colab.research.google.com/github/oobabooga/AI-Notebooks/blob/main/Colab-TextGen-GPU.ipynb)**

## Features
|
|
|
|
* Switch between different models using a dropdown menu.
|
|
* Notebook mode that resembles OpenAI's playground.
|
|
* Chat mode for conversation and role playing.
|
|
* Generate nice HTML output for GPT-4chan.
|
|
* Generate Markdown output for [GALACTICA](https://github.com/paperswithcode/galai), including LaTeX support.
|
|
* Support for [Pygmalion](https://huggingface.co/models?search=pygmalionai/pygmalion) and custom characters in JSON format (just place the files under `characters/`).
|
|
* Stream the text output in real time.
|
|
* Load parameter presets from text files.
|
|
* Load large models in 8-bit mode.
|
|
* Split large models across your GPU(s), CPU, and disk.
|
|
* CPU mode.
|
|
* Get responses via API.
|
|
* Works on Google Colab ([see the full guide](https://github.com/oobabooga/text-generation-webui/wiki/Running-on-Colab)).
|
|
|
|
## Installation
|
|
|
|
Open a terminal and copy and paste these commands one at a time ([install conda](https://docs.conda.io/en/latest/miniconda.html) first if you don't have it already):
|
|
|
|
```
|
|
conda create -n textgen
|
|
conda activate textgen
|
|
conda install pytorch torchvision torchaudio pytorch-cuda=11.7 git -c pytorch -c nvidia
|
|
git clone https://github.com/oobabooga/text-generation-webui
|
|
cd text-generation-webui
|
|
pip install -r requirements.txt
|
|
```
|
|
|
|
The third line assumes that you have an NVIDIA GPU.
|
|
|
|
* If you have an AMD GPU, you should install the ROCm version of pytorch instead.
|
|
* If you are running in CPU mode, you just need the standard pytorch and should replace the third command with this one:
|
|
|
|
```
|
|
conda install pytorch torchvision torchaudio git -c pytorch
|
|
```
|
|
|
|
Once you have completed these steps, you should be able to start the web UI. However, you will first need to download a model.
|
|
|
|
## Downloading models
|
|
|
|
Models should be placed under `models/model-name`. For instance, `models/gpt-j-6B` for [GPT-J 6B](https://huggingface.co/EleutherAI/gpt-j-6B/tree/main).
|
|
|
|
#### Hugging Face
|
|
|
|
[Hugging Face](https://huggingface.co/models?pipeline_tag=text-generation&sort=downloads) is the main place to download models. These are some noteworthy examples:
|
|
|
|
* [GPT-J 6B](https://huggingface.co/EleutherAI/gpt-j-6B/tree/main)
|
|
* [GPT-Neo](https://huggingface.co/models?pipeline_tag=text-generation&sort=downloads&search=eleutherai+%2F+gpt-neo)
|
|
* [OPT](https://huggingface.co/models?search=facebook/opt)
|
|
* [GALACTICA](https://huggingface.co/models?search=facebook/galactica)
|
|
* [\*-Erebus](https://huggingface.co/models?search=erebus)
|
|
* [Pygmalion](https://huggingface.co/models?search=pygmalion)
|
|
|
|
You can automatically download a model from HF using the script `download-model.py`. Its usage is very simple:
|
|
|
|
python download-model.py organization/model
|
|
|
|
For instance:
|
|
|
|
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 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 under `models/gpt-j-6B`:
|
|
|
|
```
|
|
python download-model.py EleutherAI/gpt-j-6B
|
|
```
|
|
|
|
You don't really need all of GPT-J 6B's files, just the tokenizer files, but you might as well download the whole thing. Those files will be automatically detected when you attempt to load GPT-4chan.
|
|
|
|
#### Converting to pytorch (optional)
|
|
|
|
The script `convert-to-torch.py` allows you to convert models to .pt format, which is sometimes 10x faster to load to the GPU:
|
|
|
|
python convert-to-torch.py models/model-name
|
|
|
|
The output model will be saved to `torch-dumps/model-name.pt`. When you load a new model, the web UI first looks for this .pt file; if it is not found, it loads the model as usual from `models/model-name`.
|
|
|
|
## Starting the web UI
|
|
|
|
conda activate textgen
|
|
python server.py
|
|
|
|
Then browse to
|
|
|
|
`http://localhost:7860/?__theme=dark`
|
|
|
|
Optionally, you can use the following command-line flags:
|
|
|
|
| Flag | Description |
|
|
|-------------|-------------|
|
|
| `-h`, `--help` | show this help message and exit |
|
|
| `--model MODEL` | Name of the model to load by default. |
|
|
| `--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.|
|
|
| `--cai-chat` | Launch the web UI in chat mode with a style similar to Character.AI's. If the file profile.png or profile.jpg exists in the same folder as server.py, this image will be used as the bot's profile picture. |
|
|
| `--cpu` | Use the CPU to generate text.|
|
|
| `--load-in-8bit` | Load the model with 8-bit precision.|
|
|
| `--auto-devices` | Automatically split the model across the available GPU(s) and CPU.|
|
|
| `--disk` | If the model is too large for your GPU(s) and CPU combined, send the remaining layers to the disk. |
|
|
| `--disk-cache-dir DISK_CACHE_DIR` | Directory to save the disk cache to. Defaults to `cache/`. |
|
|
| `--gpu-memory GPU_MEMORY` | Maximum GPU memory in GiB to allocate. This is useful if you get out of memory errors while trying to generate text. Must be an integer number. |
|
|
| `--cpu-memory CPU_MEMORY` | Maximum CPU memory in GiB to allocate for offloaded weights. Must be an integer number. Defaults to 99.|
|
|
| `--no-stream` | Don't stream the text output in real time. This improves the text generation performance.|
|
|
| `--settings SETTINGS_FILE` | Load the default interface settings from this json file. See `settings-template.json` for an example.|
|
|
| `--listen` | Make the web UI reachable from your local network.|
|
|
| `--share` | Create a public URL. This is useful for running the web UI on Google Colab or similar. |
|
|
|
|

|
|
|
|
## 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.
|
|
|
|
## System requirements
|
|
|
|
Check the [wiki](https://github.com/oobabooga/text-generation-webui/wiki/System-requirements) for some examples of VRAM and RAM usage in both GPU and CPU mode.
