💎 GEMBRAIN-31B 🧠
🧠 About The Model
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.
It's build to create the most unhinged narratives and construct image prompts about anything accordingly to a given structure with high precision.
Expect creative swipe variance, unique and non-robotic prose, and sharper instruction adherence.

Please refer to the original google/gemma-4-31b-it for the correct chat template.
Let your frontend handle the chat template if possible (e.g., Chat Completion in SillyTavern).
For Reasoning: Add <|think|> at the very beginning of the system prompt. Thinking happens between <|channel>thought\n and
<channel|> tags.
