Textgen
Open-source desktop app for local LLMs. Text, vision, tool-calling, OpenAI/Anthropic-compatible API. 100% private.
#TextGen
A desktop app for local LLMs. Open source, no telemetry. Text, vision, tool-calling, web search. UI + API.
#Get started in 1 minute
Download, unzip, double-click textgen. A window opens.
https://github.com/oobabooga/textgen/releases
Portable builds for Linux, Windows, and macOS with CUDA, Vulkan, ROCm, and CPU-only options. All dependencies included. Compatible with GGUF (llama.cpp) models.
For additional backends (ExLlamaV3, Transformers), training, image generation, and extensions, see Installation.
#Features
#Chat & generation
instructmode for instruction-following (like ChatGPT), andchat-instruct/chatmodes for talking to custom characters. Prompts are automatically formatted with Jinja2 templates.- Vision (multimodal): Attach images to messages for visual understanding (tutorial).
- File attachments: Upload text files, PDF documents, and .docx documents to talk about their contents.
- Edit messages, navigate between message versions, and branch conversations at any point.
- Notebook tab for free-form text generation outside of chat turns.
#Backends & API
- Multiple backends: llama.cpp, ik_llama.cpp, Transformers, ExLlamaV3, and TensorRT-LLM. Switch between backends and models without restarting.
- OpenAI/Anthropic-compatible API: Chat, Completions, and Messages endpoints with tool-calling support. Use as a local drop-in replacement for the OpenAI/Anthropic APIs (examples).
- Tool-calling: Models can call custom functions during chat, including web search, page fetching, and math. Each tool is a single
.pyfile. MCP servers are also supported (tutorial).
#Training & image generation
- Training: Fine-tune LoRAs on multi-turn chat or raw text datasets. Supports resuming interrupted runs (tutorial).
- Image generation: A dedicated tab for
diffusersmodels like Z-Image-Turbo. Features 4-bit/8-bit quantization and a persistent gallery with image metadata (tutorial).
#Privacy & interface
- 100% offline and private, with zero telemetry, external resources, or remote update requests.
- Dark/light themes, syntax highlighting for code blocks, and LaTeX rendering for mathematical expressions.
- Built-in and community extensions including TTS, voice input, and translation. See the extensions directory for the full list.
#Downloading models
- Download a GGUF model file from Hugging Face.
- Place it in the
user_data/modelsfolder.
That's it. The UI will detect it automatically.
For recommended GGUF quants, check out LocalBench. To estimate how much memory a model will use, try the GGUF Memory Calculator.
Other model types (Transformers, EXL3)
Models that consist of multiple files (like 16-bit Transformers models and EXL3 models) should be placed in a subfolder inside user_data/models:
textgen
└── user_data
└── models
└── Qwen_Qwen3-8B
├── config.json
├── generation_config.json
├── model-00001-of-00004.safetensors
├── ...
├── tokenizer_config.json
└── tokenizer.json
These formats require the full installation (not the portable build).
#Installation
For the desktop app, see the portable builds. The options below run the web UI in your browser instead.
#Manual portable install with venv
Fast setup on any Python 3.9+:
# Clone repository git clone https://github.com/oobabooga/textgen cd textgen # Create virtual environment python -m venv venv # Activate virtual environment # On Windows: venv\Scripts\activate # On macOS/Linux: source venv/bin/activate # Install dependencies (choose appropriate file under requirements/portable for your hardware) pip install -r requirements/portable/requirements.txt --upgrade # Launch server (basic command) python server.py --portable --api --auto-launch # When done working, deactivate deactivate
#Full installation
For users who need additional backends (ExLlamaV3, Transformers), training, image generation, or extensions like TTS, voice input, and translation. Requires ~10GB disk space and downloads PyTorch.
Installation details
#One-click installer
- Clone the repository, or download its source code and extract it.
- Run the startup script for your OS:
start_windows.bat,start_linux.sh, orstart_macos.sh. - When prompted, select your GPU vendor.
- After installation, open
http://127.0.0.1:7860in your browser.
After installation:
- Restart: run the same
start_script. - Pass command-line flags: directly (e.g.,
./start_linux.sh --help), or persist them inuser_data/CMD_FLAGS.txt(e.g.,--apito enable the API). - Update: run the update script for your OS (
update_wizard_windows.bat,update_wizard_linux.sh, orupdate_wizard_macos.sh). - Reinstall from scratch: delete the
installer_filesfolder and run thestart_script again. - Install extension requirements: use the update wizard's "Install/update extensions requirements" option. It reinstalls the main project requirements at the end to ensure they take precedence over conflicting extension dependencies.
Notes:
- These scripts (
start_,update_wizard_,cmd_) don't need to run as admin/root. - For automated installation, set the
GPU_CHOICE,LAUNCH_AFTER_INSTALL, andINSTALL_EXTENSIONSenvironment variables. Example:GPU_CHOICE=A LAUNCH_AFTER_INSTALL=FALSE INSTALL_EXTENSIONS=TRUE ./start_linux.sh. - Under the hood, the script uses Miniforge to set up a Conda environment in
installer_files/. To run anything manually in this environment, launch an interactive shell usingcmd_linux.sh,cmd_windows.bat, orcmd_macos.sh.

--trust-remote-code Set trust_remote_code=True while loading the model. Necessary for some models.
--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.

#Loading a model automatically
To skip the Model tab on every launch, add this to user_data/CMD_FLAGS.txt:
