Overview
SillyTavern is a locally installed interface for interacting with text-generation models, image-generation systems, and text-to-speech services. It does not provide hosted AI models itself.
The project began in February 2023 as a fork of TavernAI 1.2.8. It is distributed under the AGPL-3.0 license and is maintained as a community open-source project.
Users can connect local model servers or cloud providers, then manage characters, personas, prompts, chat histories, lorebooks, and generation settings from one interface.

FAQ
Does SillyTavern generate responses by itself?
No. It is an interface that connects to local or cloud AI APIs. Users must configure a compatible provider or local model backend.
Is SillyTavern free?
Yes. The software is free and open source. Connected providers may charge separately for model usage.
Which operating systems support SillyTavern?
Official installation documentation covers Windows, Linux, macOS, Android through Termux, and Docker deployments.
Does SillyTavern have an API?
SillyTavern connects to external LLM, image, and voice APIs. It also supports extensions and server plugins that can add functionality and endpoints.
Is there a free trial?
There is no separate trial period because the SillyTavern software itself is free. Any trial or free allowance depends on the selected external provider.
Can SillyTavern run entirely locally?
Yes, when paired with a local model server such as Ollama, llama.cpp, KoboldCpp, or another supported backend. Hardware requirements then depend on the selected model.
