Overview

About this model

Cydonia 24B v4.1 is a 24B community fine-tune tuned for creative writing, character chat and interactive fiction (it is not abliterated), with a 131K-token context window. Muapi exposes it through a single REST endpoint with async polling and Server-Sent Events streaming, so you can drop it into chat apps, agents and workflows without hosting GPUs. It is best suited to long-running character chats and story writing. Pricing is pay-per-token at $0.7/M input tokens and $1.1/M output tokens, with no subscription. See also Aion Llama 3.1 8B. Browse the full lineup on the Cydonia Character Chat API page or the Character Chat LLM API hub and the Abliterated LLM API hub. Mature themes are permitted only within Muapi's acceptable-use policy, and output quality and behavior vary by prompt.
