LibreChat vs SillyTavern

LibreChat has no write-up on Specifiction yet; its figures are above.

SillyTavern is a locally installed interface for interacting with text-generation models, image-generation engines, and text-to-speech voice models. Users can create, import, and switch between character cards, then return to chat histories or review them. The interface includes group chats, lorebooks, personas, prompt controls, chat commands, scripting, and built-in retrieval-augmented generation. Extensions can add character sprites, chat summarization and translation, image generation, text-to-speech, and web search. SillyTavern works with local and cloud model backends, including KoboldCpp, llama.cpp, Ollama, OpenAI, Claude, Mistral, OpenRouter, and AI Horde. The project says it will remain free and open source under AGPL-3.0 and provides no hosted service. It says it does not programmatically track user data, though cloud providers may log information sent to them. Local use requires a system supporting NodeJS 20 or higher; documentation recommends an NVIDIA 3000-series GPU with at least 6GB of VRAM for local inference. The app was not designed for very large character libraries, and performance can degrade above 1,000 characters.
