Text generation web UI

A Gradio web UI for Large Language Models.

Its goal is to become the AUTOMATIC1111/stable-diffusion-webui of text generation.

Features

To learn how to use the various features, check out the Documentation: https://github.com/oobabooga/text-generation-webui/tree/main/docs

Installation

One-click installers

  1. Clone or download the repository.
  2. Run the start_linux.sh, start_windows.bat, start_macos.sh, or start_wsl.bat script depending on your OS.
  3. Select your GPU vendor when asked.
  4. Have fun!

How it works

The script creates a folder called installer_files where it sets up a Conda environment using Miniconda. The installation is self-contained: if you want to reinstall, just delete installer_files and run the start script again.

To launch the webui in the future after it is already installed, run the same start script.

Getting updates

Run update_linux.sh, update_windows.bat, update_macos.sh, or update_wsl.bat.

Running commands

If you ever need to install something manually in the installer_files environment, you can launch an interactive shell using the cmd script: cmd_linux.sh, cmd_windows.bat, cmd_macos.sh, or cmd_wsl.bat.

Defining command-line flags

To define persistent command-line flags like --listen or --api, edit the CMD_FLAGS.txt file with a text editor and add them there. Flags can also be provided directly to the start scripts, for instance, ./start-linux.sh --listen.

Other info

  • There is no need to run any of those scripts as admin/root.
  • For additional instructions about AMD setup, WSL setup, and nvcc installation, consult this page.
  • The installer has been tested mostly on NVIDIA GPUs. If you can find a way to improve it for your AMD/Intel Arc/Mac Metal GPU, you are highly encouraged to submit a PR to this repository. The main file to be edited is one_click.py.
  • For automated installation, you can use the GPU_CHOICE, LAUNCH_AFTER_INSTALL, and INSTALL_EXTENSIONS environment variables. For instance: GPU_CHOICE=A LAUNCH_AFTER_INSTALL=False INSTALL_EXTENSIONS=False ./start_linux.sh.

Manual installation using Conda

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

0. Install Conda

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

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

curl -sL "https://repo.anaconda.com/miniconda/Miniconda3-latest-Linux-x86_64.sh" > "Miniconda3.sh"
bash Miniconda3.sh

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/WSL CPU only pip3 install torch torchvision torchaudio --index-url https://download.pytorch.org/whl/cpu
Linux AMD pip3 install torch torchvision torchaudio --index-url https://download.pytorch.org/whl/rocm5.4.2
MacOS + MPS Any pip3 install torch torchvision torchaudio
Windows NVIDIA pip3 install torch torchvision torchaudio --index-url https://download.pytorch.org/whl/cu117
Windows CPU only pip3 install torch torchvision torchaudio

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

3. Install the web UI

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

AMD, Metal, Intel Arc, and CPUs without AVX2

  1. Replace the last command above with
pip install -r requirements_nowheels.txt
  1. Manually install llama-cpp-python using the appropriate command for your hardware: Installation from PyPI.

  2. Do the same for CTransformers: Installation.

  3. AMD: Manually install AutoGPTQ: Installation.

  4. AMD: Manually install ExLlama by simply cloning it into the repositories folder (it will be automatically compiled at runtime after that):

cd text-generation-webui
git clone https://github.com/turboderp/exllama repositories/exllama

bitsandbytes on older NVIDIA GPUs

bitsandbytes >= 0.39 may not work. In that case, to use --load-in-8bit, you may have to downgrade like this:

  • Linux: pip install bitsandbytes==0.38.1
  • Windows: pip install https://github.com/jllllll/bitsandbytes-windows-webui/raw/main/bitsandbytes-0.38.1-py3-none-any.whl

Alternative: Docker

ln -s docker/{Dockerfile,docker-compose.yml,.dockerignore} .
cp docker/.env.example .env
# Edit .env and set TORCH_CUDA_ARCH_LIST based on your GPU model
docker compose up --build
  • You need to have docker compose v2.17 or higher installed. See this guide for instructions.
  • For additional docker files, check out this repository.

Updating the requirements

From time to time, the requirements.txt changes. To update, use these commands:

conda activate textgen
cd text-generation-webui
pip install -r requirements.txt --upgrade

Downloading models

Models should be placed in the text-generation-webui/models folder. They are usually downloaded from Hugging Face.

  • Transformers or GPTQ models are made of several files and must be placed in a subfolder. Example:
text-generation-webui
├── models
│   ├── lmsys_vicuna-33b-v1.3
│   │   ├── config.json
│   │   ├── generation_config.json
│   │   ├── pytorch_model-00001-of-00007.bin
│   │   ├── pytorch_model-00002-of-00007.bin
│   │   ├── pytorch_model-00003-of-00007.bin
│   │   ├── pytorch_model-00004-of-00007.bin
│   │   ├── pytorch_model-00005-of-00007.bin
│   │   ├── pytorch_model-00006-of-00007.bin
│   │   ├── pytorch_model-00007-of-00007.bin
│   │   ├── pytorch_model.bin.index.json
│   │   ├── special_tokens_map.json
│   │   ├── tokenizer_config.json
│   │   └── tokenizer.model
  • GGUF models are a single file and should be placed directly into models. Example:
text-generation-webui
├── models
│   ├── llama-2-13b-chat.Q4_K_M.gguf

In both cases, you can use the "Model" tab of the UI to download the model from Hugging Face automatically. It is also possible to download via the command-line with python download-model.py organization/model (use --help to see all the options).

GPT-4chan

Instructions

GPT-4chan has been shut down from Hugging Face, so you need to download it elsewhere. You have two options:

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.
  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

When you load this model in default or notebook modes, the "HTML" tab will show the generated text in 4chan format:

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

Flag Description
-h, --help Show this help message and exit.
--multi-user Multi-user mode. Chat histories are not saved or automatically loaded. WARNING: this is highly experimental.
--character CHARACTER The name of the character to load in chat mode by default.

--lora LORA [LORA ...] The list of LoRAs to load. If you want to load more than one LoRA, write the names separated by spaces.
--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 yaml file. See settings-template.yaml for an example. If you create a file called settings.yaml, 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.
--chat-buttons Show buttons on chat tab instead of hover menu.

Model loader

Flag Description

--cpu Use the CPU to generate text. Warning: Training on CPU is extremely slow.
--auto-devices Automatically split the model across the available GPU(s) and CPU.
--gpu-memory GPU_MEMORY [GPU_MEMORY ...] Maximum GPU memory in GiB to be allocated per GPU. Example: --gpu-memory 10 for a single GPU, --gpu-memory 10 5 for two GPUs. You can also set values in MiB like --gpu-memory 3500MiB.

--load-in-8bit Load the model with 8-bit precision (using bitsandbytes).
--bf16 Load the model with bfloat16 precision. Requires NVIDIA Ampere GPU.
