What is the Llama Character Chat API?

This page covers 8 models on Muapi. Each is listed below with its context window, input modality and pricing.

Senden Sie einen Prompt, optional mit einem System-Prompt zur Definition von Persönlichkeit und Tonfall sowie einer Bild-URL bei vision-fähigen Modellen, und rufen Sie den generierten Text ab. Typische Anwendungsfälle umfassen Charakter-Rollenspiele, interaktive Geschichten, ausführliches Storytelling und eigene Chat-Anwendungen. Dies sind feinabgestimmte Community-Modelle für kreatives Schreiben und Dialoge – sie sind nicht abliterated. Die Nutzungsrichtlinien von MuAPI gelten für alle generierten Inhalte. Sie bleiben für die Verwendung der Ausgaben verantwortlich.

Hauptfunktionen

8 Models, One API

Every endpoint accepts the same request body and returns text through the shared result endpoint, so switching models is a one-line change.

Tuned for Creative Writing

These models are fine-tuned on fiction and character chat data, so they tend to hold a character, keep a narrative voice, and write longer, more vivid prose than general assistants.

System Prompt Control

Set a system_prompt to steer persona, tone, and output format for creative, analytical, or evaluation work.

Pay Per Token

Billing follows the token counts each call returns. There is no subscription and no model hosting to manage.

Long-Form Text Generation

Use these models for chat, drafting, and step-by-step reasoning.

Acceptable-Use Policy Applies

Reduced refusals do not mean no rules. Muapi's acceptable-use policy and applicable law still apply to what you generate.

Häufig gestellte Fragen

What is a character chat LLM?

A character chat LLM is a language model fine-tuned on fiction, dialogue and character chat data so it holds a character, keeps a narrative voice, and writes longer, more vivid prose. The models on this page are community fine-tunes tuned for creative writing, not abliterated versions of general assistants.

Which models does the Llama Character Chat API include?

Anubis 70B v1.1, Euryale 70B v2.3, Stheno 8B v3.2, EVA Llama 3.33 70B, MythoMax 13B, Wayfarer 70B, Nevoria R1 70B and Magnum v4 72B. Each is a separate endpoint with its own model name in the URL.

How much does it cost?

Billing is per token, deducted after each call from the counts the model returns. Rates start at $0.201 per million input tokens; see the pricing table for every model.

Will these models answer anything I ask?

No. Reduced refusals do not mean unrestricted output, and each model's knowledge and quality still bound the answer. You are responsible for how you use the output, and requests that violate Muapi's acceptable-use policy or the law are not permitted.

Can I send images to these models?

No. Every model on this page is text in, text out.

How do I get the result?

POST to /api/v1/<model-name> returns a request_id. Poll /api/v1/predictions/{request_id}/result until the status is completed, then read the text from outputs.

Can I use these for a character or storytelling app?

Yes: set a system_prompt with the character's persona and send the running conversation in the prompt. Muapi's acceptable-use policy applies, and you are responsible for moderating your own product.
