Extras project is discontinued and won't receive any new updates or modules. The vast majority of modules are available natively in the main SillyTavern application. You may still install and use it but don't expect to get immediate support if you face any issues.
- April 24 2024 - The project is officially discontinued.
- November 20 2023 - The project is relicensed as AGPLv3 to comply with the rest of ST organization policy. If you have any concerns about that, please raise a discussion in the appropriate channel.
- November 16 2023 - Requirement files were remade from scratch to simplify the process of local installation.
- Removed requirements-complete.txt, please use requirements.txt instead.
- Unlocked versions of all requirements unless strictly necessary.
- Coqui TTS requirements moved to requirements-coqui.txt.
- July 25 2023 - Now extras require Python 3.11 to run, some of the new modules will be incompatible with old Python 3.10 installs. To migrate using conda, please remove old environment using
conda remove --name extras --alland reinstall using the instructions below.
A set of APIs for various SillyTavern extensions.
You need to run the latest version of SillyTavern. Grab it here: How to install, Git repository
All modules, except for Stable Diffusion, run on the CPU by default. However, they can alternatively be configured to use CUDA (with --cuda command line option). When running all modules simultaneously, you can expect a usage of approximately 6 GB of RAM. Loading Stable Diffusion adds an additional couple of GB to the memory usage.
Some modules can be configured to use CUDA separately from the rest (e.g. --talkinghead-gpu, --coqui-gpu command line options). This is useful in low-VRAM setups, such as on a gaming laptop.
Try on Colab (will give you a link to Extras API):
Colab link: https://colab.research.google.com/github/SillyTavern/SillyTavern/blob/release/colab/GPU.ipynb
Documentation: https://docs.sillytavern.app/
- Default requirements.txt installs PyTorch CUDA by default.
- If you run on AMD GPU, use requirements-rocm.txt file instead.
- If you run on Apple Silicon (ARM series), use the requirements-silicon.txt file instead.
- If you want to use Coqui TTS, install requirements-coqui.txt after choosing the requirements from the list above.
- If you want to use RVC, install requirements-rvc.txt after choosing the requirements from the list above.
- BE WARNED THAT:
- Coqui package is extremely unstable and may break other packages or not work at all in your environment.
- It's not really worth it.
ERROR: Could not build wheels for hnswlib, which is required to install pyproject.toml-based projects
Installing the chromadb package requires one of the following:
- Have Visual C++ build tools installed: https://visualstudio.microsoft.com/visual-cpp-build-tools/
- Installing hnswlib from conda:
conda install -c conda-forge hnswlib
❗ IMPORTANT! The chromadb package is used only by the chromadb module for the old Smart Context extension, which is deprecated. You will likely not need it.
You must specify a list of module names to be run in the --enable-modules command (caption provided as an example). See Modules section.

Installation requirements for Talkinghead changed in January 2024. The live mode - i.e. the talkinghead module that powers the Talkinghead mode of Character Expressions - no longer needs any additional packages.
However, a manual poser app has been added, serving two purposes. First, it is a GUI editor for the Talkinghead emotion templates. Secondly, it can batch-generate static emotion sprites from a single Talkinghead image. The latter can be convenient if you want the convenience of AI-powered posing (e.g. if you make new characters often), but don't want to run the live mode.
The manual poser app, and only that app, still requires the installation of an additional package that is not installed automatically due to incompatibility with Colab. If you want to be able to use the manual poser app, then run this after you have installed other requirements:
conda activate extras
pip install wxpython==4.2.1
The installation of the wxpython package can easily take half an hour on a fast CPU, as it needs to compile a whole GUI toolkit.
More information about Talkinghead can be found in its full documentation.

❗ IMPORTANT! ChromaDB is used only by the chromadb module for the old Smart Context extension, which is deprecated. You will likely not need it.
ChromaDB is a blazing fast and open source database that is used for long-term memory when chatting with characters. It can be run in-memory or on a local server on your LAN.
NOTE: You should NOT run ChromaDB on a cloud server. There are no methods for authentication (yet), so unless you want to expose an unauthenticated ChromaDB to the world, run this on a local server in your LAN.
Run the extras server with the chromadb module enabled (recommended).
Use this if you want to use ChromaDB with docker or host it remotely. If you don't know what that means and only want to use ChromaDB with ST on your local device, use the 'in-memory' instructions instead.
Prerequisites: Docker, Docker compose (make sure you're running in rootless mode with the systemd service enabled if on Linux).
Steps:
- Run
git clone https://github.com/chroma-core/chroma chromadbandcd chromadb - Run
docker-compose up -d --buildto build ChromaDB. This may take a long time depending on your system - Once the build process is finished, ChromaDB should be running in the background. You can check with the command
docker ps - On your client machine, specify your local server ip in the
--chroma-hostargument (ex.--chroma-host=192.168.1.10)
If you are running ChromaDB on the same machine as SillyTavern, you will have to change the port of one of the services. To do this for ChromaDB:
- Run
docker psto get the container ID and thendocker container stop <container ID> - Enter the ChromaDB git repository
cd chromadb - Open
docker-compose.ymland look for the line starting withuvicorn chromadb.app:app - Change the
--portargument to whatever port you want. - Look for the
portscategory and change the occurrences of8000to whatever port you chose in step 4. - Save and exit. Then run
docker-compose up --detach - On your client machine, make sure to specity the
--chroma-portargument (ex.--chroma-port=<your-port-here>) along with the--chroma-hostargument.

GET /api/tts/sample/<voice_id>
WAV audio file.
POST /api/embeddings/compute
This is a vectorization source (text embedding provider) for the Vector Storage built-in extension of ST.
If you have many text items to vectorize (e.g. chat history, or chunks for RAG ingestion), send them in all at once. This allows the backend to batch the input, allocating the available compute resources efficiently, and thus running much faster (compared to processing a single item at a time).
The embeddings are always normalized.
For one text item:
{ "text": "The quick brown fox jumps over the lazy dog." }
For multiple text items, just put them in an array:
{ "text": ["The quick brown fox jumps over the lazy dog.",
"Lorem ipsum dolor sit amet, consectetur adipiscing elit.",
...] }
When the input was one text item, returns one vector (the embedding of that text item) as an array:
{ "embedding": [numbers] }
When the input was multiple text items, returns multiple vectors (one for each input text item) as an array of arrays:
{ "embedding": [[numbers],
[numbers], ...] }
