What is SillyTavern?

SillyTavern is LLM frontend for power users: character creation, roleplay, and deep prompt control. In practice, SillyTavern works as an AI roleplay platform in the ecosystem of apps and agents that call LLMs over APIs.

People searching “what is SillyTavern” usually compare SillyTavern with other tools in the same cluster (Roleplay). On public usage rankings (e.g. OpenRouter), SillyTavern shows up there — adoption context, not Geek Hub token volumes.

If you want to run SillyTavern with Claude, GPT, Gemini, or open-source models without locking to one vendor, the useful setup is: SillyTavern + an OpenAI-compatible gateway (Geek Hub).

SillyTavern pricing and plans

SillyTavern pricing depends on the product (free, freemium, subscription, or open-source). Always check the official SillyTavern page at sillytavern.app before you decide.

Even when SillyTavern is free or freemium, model usage via API is usually billed separately. That’s why many teams connect SillyTavern to a gateway like Geek Hub: one key, many models, spend control.

How to use SillyTavern with Geek Hub (OpenAI-compatible API)

Many chat and roleplay UIs accept an OpenAI-compatible endpoint. Configure SillyTavern with Geek Hub’s base URL so SillyTavern isn’t locked to one provider.

Does SillyTavern work with Geek Hub?
If SillyTavern supports an OpenAI-compatible provider, yes: configure SillyTavern with base URL https://api.geekhub.mx/v1 and your Geek Hub API key. If SillyTavern only speaks closed proprietary APIs, this SillyTavern guide is still a useful overview, but wiring may not apply.
How do I use SillyTavern with Claude, GPT, or Gemini?
In SillyTavern, pick a custom / OpenAI-compatible provider when available, point it at Geek Hub, and select the model id (e.g. anthropic/…, openai/…, google/…). That way SillyTavern switches models without switching apps.
Is SillyTavern free?
It depends on SillyTavern’s plan. Many tools are freemium or open-source at the core; model tokens are paid to the provider or gateway. Check pricing at sillytavern.app.
Does Geek Hub republish OpenRouter token volumes for SillyTavern?
No. Public ranking volumes are not Geek Hub metrics. In Geek Hub you only see your account’s usage when calling models from SillyTavern or other apps.
