Model Card

MythoMax L2 13B is a 13-billion-parameter language model created by Gryphe, built on Llama 2 and specialized for creative writing, storytelling, and character roleplay.

Rather than being trained from scratch, it was produced by merging two models — MythoLogic-L2 and Huginn — using an experimental tensor-level blending technique. MythoLogic-L2 contributes strong comprehension at the input layers while Huginn drives expressive writing at the output layers, resulting in unusually coherent long-form narrative generation for its size.

The model excels at maintaining consistent character voice across extended exchanges, producing dialogue and scene descriptions with natural pacing. It's a strong fit for interactive fiction, RPG dialogue generation, and narrative branching where frontier-model API costs would be prohibitive. Context length is 4,096 tokens. Not recommended for reasoning, coding, or factual tasks.
