Why This Model
nbeerbower’s Mistral-Nemo-Gutenberg-Encore, a 12B model fine-tuned from Mistral-Nemo-Instruct using ORPO (Odds Ratio Preference Optimization) on 7 distinct fiction and dialogue datasets: Gutenberg DPO, synthetic fiction, Arkhaios, Purpura, Schule, and more. Scored 40/50 versus stock Nemo’s 34/50 on creative writing evaluation with o3 as judge. Produces distinctly “book-like” prose — the kind of writing that reads like it was excerpted from a published novel, not generated by a language model. The 12B parameter count gives it more nuanced vocabulary and narrative structure than 8B alternatives.
Default System Prompt
Minimal by design — the model's fine-tuning does the heavy lifting. Override with a custom system parameter if needed.
Write book-quality prose. Literary fiction, novel-grade writing, rich descriptive language. Extended narrative.
