<p style="margin-bottom: 0;">Gembrain-31B is a synthesis of several models, including Gemsicle-31B as important ingredient. The goal of this release was to stabilize and improve the initial Gemsicle-31B, but also to enhance its logical and lateral thinking, both with and without reasoning.</p>

***

<p style="margin-bottom: 0;">It's build to create the most unhinged narratives and construct image prompts about anything accordingly to a given structure with high precision.</p>

***

<p style="margin-bottom: 0;">Expect creative swipe variance, unique and non-robotic prose, and sharper instruction adherence.</p>
