Features

  • Multiple backends for text generation in a single UI and API, including Transformers, llama.cpp (through llama-cpp-python), ExLlamaV2, AutoGPTQ, and TensorRT-LLM. AutoAWQ, HQQ, and AQLM are also supported through the Transformers loader.
  • OpenAI-compatible API server with Chat and Completions endpoints – see the examples.
  • Automatic prompt formatting for each model using the Jinja2 template in its metadata.
  • Three chat modes: instruct, chat-instruct, and chat, allowing for both instruction-following and casual conversations with characters. chat-instruct mode automatically applies the model's template to the chat prompt, ensuring high-quality outputs without manual setup.
  • "Past chats" menu to quickly switch between conversations and start new ones.
  • Free-form generation in the Default/Notebook tabs without being limited to chat turns. Send formatted chat conversations from the Chat tab to these tabs.
  • Multiple sampling parameters and generation options for sophisticated text generation control.
  • Easy switching between different models through the UI without restarting, using the "Model" tab.
  • Simple LoRA fine-tuning tool to customize models with your data.
  • All in one folder. The requirements are installed in a self-contained installer_files folder that doesn't interfere with the system's environment.
  • Extensions support, including numerous built-in and user-contributed extensions. See the wiki and the extensions directory for details.

How to install

  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. Once the installation ends, browse to http://localhost:7860.
  5. Have fun!

To restart the web UI in the future, run the start_ script again.

This script creates an installer_files folder where it sets up the project's requirements. If you need to reinstall the requirements, just delete that folder and start the web UI again.

The script accepts command-line flags, such as ./start_linux.sh --help. Alternatively, you can edit the CMD_FLAGS.txt file with a text editor and add your flags there, such as --api in case you need to use the API.

To get updates in the future, run update_wizard_linux.sh, update_wizard_windows.bat, update_wizard_macos.sh, or update_wizard_wsl.bat.

Setup details and information about installing manually

One-click-installer

The script uses Miniconda to set up a Conda environment in the installer_files folder.

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.

  • There is no need to run any of those scripts (start_, update_wizard_, or cmd_) as admin/root.
  • To install the requirements for extensions, you can use the extensions_reqs script for your OS. At the end, this script will install the main requirements for the project to make sure that they take precedence in case of version conflicts.
  • For additional instructions about AMD and WSL setup, consult the documentation.
  • For automated installation, you can use the GPU_CHOICE, USE_CUDA118, LAUNCH_AFTER_INSTALL, and INSTALL_EXTENSIONS environment variables. For instance: GPU_CHOICE=A USE_CUDA118=FALSE LAUNCH_AFTER_INSTALL=FALSE INSTALL_EXTENSIONS=TRUE ./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=3.11
conda activate textgen

2. Install Pytorch

System GPU Command
Linux/WSL NVIDIA pip3 install torch==2.2.2 torchvision==0.17.2 torchaudio==2.2.2 --index-url https://download.pytorch.org/whl/cu121
Linux/WSL CPU only pip3 install torch==2.2.2 torchvision==0.17.2 torchaudio==2.2.2 --index-url https://download.pytorch.org/whl/cpu
Linux AMD pip3 install torch==2.2.2 torchvision==0.17.2 torchaudio==2.2.2 --index-url https://download.pytorch.org/whl/rocm5.6
MacOS + MPS Any pip3 install torch==2.2.2 torchvision==0.17.2 torchaudio==2.2.2
Windows NVIDIA pip3 install torch==2.2.2 torchvision==0.17.2 torchaudio==2.2.2 --index-url https://download.pytorch.org/whl/cu121
Windows CPU only pip3 install torch==2.2.2 torchvision==0.17.2 torchaudio==2.2.2

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

For NVIDIA, you also need to install the CUDA runtime libraries:

conda install -y -c "nvidia/label/cuda-12.1.1" cuda-runtime

If you need nvcc to compile some library manually, replace the command above with

conda install -y -c "nvidia/label/cuda-12.1.1" cuda

3. Install the web UI

git clone https://github.com/oobabooga/text-generation-webui
cd text-generation-webui
pip install -r <requirements file according to table below>

Requirements file to use:

GPU CPU requirements file to use
NVIDIA has AVX2 requirements.txt
NVIDIA no AVX2 requirements_noavx2.txt
AMD has AVX2 requirements_amd.txt
AMD no AVX2 requirements_amd_noavx2.txt
CPU only has AVX2 requirements_cpu_only.txt
CPU only no AVX2 requirements_cpu_only_noavx2.txt
Apple Intel requirements_apple_intel.txt
Apple Apple Silicon requirements_apple_silicon.txt

Start the web UI

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

Then browse to

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

AMD GPU on Windows

  1. Use requirements_cpu_only.txt or requirements_cpu_only_noavx2.txt in the command above.

  2. Manually install llama-cpp-python using the appropriate command for your hardware: Installation from PyPI.

  3. Manually install AutoGPTQ: Installation.

    • Perform the from-source installation - there are no prebuilt ROCm packages for Windows.
Older NVIDIA GPUs
  1. For Kepler GPUs and older, you will need to install CUDA 11.8 instead of 12:
pip3 install torch==2.2.2 torchvision==0.17.2 torchaudio==2.2.2 --index-url https://download.pytorch.org/whl/cu118
conda install -y -c "nvidia/label/cuda-11.8.0" cuda-runtime
  1. 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
Manual install

The requirements*.txt above contain various wheels precompiled through GitHub Actions. If you wish to compile things manually, or if you need to because no suitable wheels are available for your hardware, you can use requirements_nowheels.txt and then install your desired loaders manually.

  --verbose                                      Print the prompts to the terminal.
  --chat-buttons                                 Show buttons on the chat tab instead of a hover menu.
  --idle-timeout IDLE_TIMEOUT                    Unload model after this many minutes of inactivity. It will be automatically reloaded when you try to use it again.

Model loader:
  --loader LOADER                                Choose the model loader manually, otherwise, it will get autodetected. Valid options: Transformers, llama.cpp, llamacpp_HF, ExLlamav2_HF, ExLlamav2,
                                                 AutoGPTQ.

Transformers/Accelerate:
  --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.

  --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".
  --load-in-8bit                                 Load the model with 8-bit precision (using bitsandbytes).
  --bf16                                         Load the model with bfloat16 precision. Requires NVIDIA Ampere GPU.
  --no-cache                                     Set use_cache to False while generating text. This reduces VRAM usage slightly, but it comes at a performance cost.

  --force-safetensors                            Set use_safetensors=True while loading the model. This prevents arbitrary code execution.
  --no_use_fast                                  Set use_fast=False while loading the tokenizer (it's True by default). Use this if you have any problems related to use_fast.
  --use_flash_attention_2                        Set use_flash_attention_2=True while loading the model.
  --use_eager_attention                          Set attn_implementation= eager while loading the model.

llama.cpp:
  --flash-attn                                   Use flash-attention.
  --tensorcores                                  NVIDIA only: use llama-cpp-python compiled with tensor cores support. This may increase performance on newer cards.
  --n_ctx N_CTX                                  Size of the prompt context.
  --threads THREADS                              Number of threads to use.

  --no-mmap                                      Prevent mmap from being used.
  --mlock                                        Force the system to keep the model in RAM.
  --n-gpu-layers N_GPU_LAYERS                    Number of layers to offload to the GPU.
  --tensor_split TENSOR_SPLIT                    Split the model across multiple GPUs. Comma-separated list of proportions. Example: 60,40.
  --numa                                         Activate NUMA task allocation for llama.cpp.
  --logits_all                                   Needs to be set for perplexity evaluation to work. Otherwise, ignore it, as it makes prompt processing slower.
  --no_offload_kqv                               Do not offload the K, Q, V to the GPU. This saves VRAM but reduces the performance.
  --cache-capacity CACHE_CAPACITY                Maximum cache capacity (llama-cpp-python). Examples: 2000MiB, 2GiB. When provided without units, bytes will be assumed.
  --row_split                                    Split the model by rows across GPUs. This may improve multi-gpu performance.
  --streaming-llm                                Activate StreamingLLM to avoid re-evaluating the entire prompt when old messages are removed.
  --attention-sink-size ATTENTION_SINK_SIZE      StreamingLLM: number of sink tokens. Only used if the trimmed prompt does not share a prefix with the old prompt.
  --tokenizer-dir TOKENIZER_DIR                  Load the tokenizer from this folder. Meant to be used with llamacpp_HF through the command-line.

ExLlamaV2:

  --autosplit                                    Autosplit the model tensors across the available GPUs. This causes --gpu-split to be ignored.
  --max_seq_len MAX_SEQ_LEN                      Maximum sequence length.
  --cfg-cache                                    ExLlamav2_HF: Create an additional cache for CFG negative prompts. Necessary to use CFG with that loader.

  --cache_4bit                                   Use Q4 cache to save VRAM.
  --num_experts_per_token NUM_EXPERTS_PER_TOKEN  Number of experts to use for generation. Applies to MoE models like Mixtral.

AutoGPTQ:
  --triton                                       Use triton.
  --no_inject_fused_mlp                          Triton mode only: disable the use of fused MLP, which will use less VRAM at the cost of slower inference.
  --no_use_cuda_fp16                             This can make models faster on some systems.
  --desc_act                                     For models that do not have a quantize_config.json, this parameter is used to define whether to set desc_act or not in BaseQuantizeConfig.
  --disable_exllama                              Disable ExLlama kernel, which can improve inference speed on some systems.

  --gradio-auth GRADIO_AUTH                      Set Gradio authentication password in the format "username:password". Multiple credentials can also be supplied with "u1:p1,u2:p2,u3:p3".
  --gradio-auth-path GRADIO_AUTH_PATH            Set the Gradio authentication file path. The file should contain one or more user:password pairs in the same format as above.
  --ssl-keyfile SSL_KEYFILE                      The path to the SSL certificate key file.
  --ssl-certfile SSL_CERTFILE                    The path to the SSL certificate cert file.
  --subpath SUBPATH                              Customize the subpath for gradio, use with reverse proxy

API:
  --api                                          Enable the API extension.
  --public-api                                   Create a public URL for the API using Cloudfare.
  --public-api-id PUBLIC_API_ID                  Tunnel ID for named Cloudflare Tunnel. Use together with public-api option.

Downloading models

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

  • 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
  • The remaining model types (like 16-bit transformers models and 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

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 it via the command-line with

python download-model.py organization/model

Run python download-model.py --help to see all the options.
