Gemma 4 31B MeroMero is a fiction fine-tune: trained on long-form stories and character dialogue, it holds a character's voice, follows a scenario and writes at length without the stock refusal layer.
Every request is routed to the build’s live route and settled to the token at the prices above. The daily real-model check sends a fixed prompt to every model and records whether the answer still matches; this model’s verdict today is “Steady since Oct 29”.
Use it from the OpenAI SDK, from SillyTavern or Janitor, or from a coding agent. Keys and top-ups live in the console.

Gemma 4 31B MeroMero in SillyTavern and Janitor AI: what to set
The three fields are the base URL, the key and the model id, as in the settings above. What differs by build is the reply length, the reasoning switch and the context size, and those decide both whether a reply arrives whole and what each message costs.
- Context Size up to 262,144 tokens, the window the catalog lists for gemma-4-31b-meromero. Every message resends the context, so set it to what the chat needs rather than the maximum.
- A fiction tune answers at once, with no reasoning step: a Max Response Length of 300 to 600 tokens fits a chat reply.
A request that fails before the model answers is not billed. A refusal written as ordinary text is billed like any answer, which is the reason to send this build rather than a stock model with a preamble.
