What is Boomslang?

Boomslang is a 3.1 billion parameter model developed by Monster-Code, built upon the robust Qwen2.5-3B-Instruct architecture. It addresses the common challenge where small models either hallucinate in arithmetic or lose conversational fluency when specialized in math. Boomslang is uniquely fine-tuned to bridge this gap, offering strong mathematical reasoning capabilities without sacrificing natural language interaction.

Key Capabilities

  • Deep Chain-of-Thought Reasoning: Trained on datasets like DeepSeek-R1 Distilled Proofs, it develops an internal self-reflection loop (<think> ... </think>) to break down complex algebraic expressions, geometry, and multi-step deduction.
  • Precise Arithmetic: Calibrated with openai/gsm8k to ensure strict adherence to order-of-operations and unambiguous answer derivation.
  • Conversational Fluency: Despite its mathematical prowess, Boomslang maintains the ability to engage in natural conversations and follow general instructions.
  • Edge-Friendly: As a 3B parameter model, it is designed for high-efficiency performance on local machines and edge devices.

Good For

  • Applications requiring methodical problem-solving in algebra, logic, and word puzzles.
  • Use cases where a compact model needs to perform reliable mathematical reasoning.
  • Scenarios demanding a balance between conversational ability and precise analytical thinking.
