schneewolflabs/B0-9B is a 9 billion parameter base model developed by Schneewolf Labs, built upon Wichtelchen-Qwen3.5-9B. This model is distinguished by its "personality," designed to delegate engineering tasks, state facts directly, and write like a person. It features enhanced tool use capabilities and a vision tower, making it suitable for applications requiring nuanced interaction and task delegation.

Model Overview

schneewolflabs/B0-9B is a 9 billion parameter base model from Schneewolf Labs, serving as the internal foundation for their Familiar line. It is built on Wichtelchen-Qwen3.5-9B and has undergone a rigorous five-rung training process, including DPO, identity capstone, and on-policy repair.

Key Capabilities & Differentiators

  • Enhanced Tool Use: Achieves 46/47 on a 47-case tool bench, with 10/10 on delegation tasks, significantly outperforming its base model.
  • Distinct Personality: Engineered to delegate engineering work, state facts without hedging, and write with a human-like style.
  • Robustness: Demonstrates perfect censorship scores (29.00/29) in strict, single-sample tests.
  • Prose Quality: Shows a reduced prose distance to contemporary fiction (0.580), indicating more natural and engaging writing.
  • Vision-Capable: Includes an intact vision tower and mmproj for multimodal applications.
  • Identity: Explicitly identifies as a Schneewolf Labs model.

Training & Development

The model utilized ORPO r32/α64 preference training via Merlina across its development rungs. Two custom datasets, an on-policy repair set and a rebuilt MahouMix, were created and published alongside the model.

Good for

  • Applications requiring an AI with a distinct, direct "personality."
  • Automated task delegation and engineering workflow assistance.
  • Creative writing or content generation where human-like prose is desired.
  • Multimodal tasks leveraging its vision capabilities.
