## SillyTavern API questions

The [setup guide](https://outrun.to/docs/setup/sillytavern) covers context, response length and streaming.

### Which API should I use with SillyTavern?

Any OpenAI-compatible API works through the Custom (OpenAI-compatible) Chat Completion source. With Outrun you use one key at https://api.outrun.to/v1 and pick any model ID.

### How much do 100 SillyTavern turns cost?

At 16k tokens of context per turn and 300 output tokens, 100 turns cost from $0.04 on Claude Haiku 5.5 (2). Less-restricted models start at $0.16 on GLM-5.3 Flash Uncensored.

### Which connection settings do I use?

API type Chat Completion, source Custom (OpenAI-compatible), custom endpoint https://api.outrun.to/v1, then your Outrun key and a model ID. Do not append /chat/completions.

### Can I use uncensored models in SillyTavern?

Yes. Uncensored and abliterated models use the same key and endpoint. The Terms still apply, and you must be 18 or older.

### Why does context size change the cost?

SillyTavern sends the chat history with every message, so each turn is billed for all the context tokens it sends. A smaller context lowers the cost per turn.

### Does Outrun keep my chats?

Outrun does not store your prompts, images or outputs unless you choose to save them.
