d-s-b/Router

Router Model Overview

The d-s-b/Router is a specialized language model designed to classify input queries based on their reasoning complexity. This 0.3 billion parameter model, fine-tuned from the Gemma 3 270M base, serves as an efficient routing mechanism for diverse reasoning tasks.

Key Capabilities

• Reasoning Classification: Accurately categorizes queries into three distinct reasoning levels:
  • no_reasoning: For direct factual lookups or simple recall (e.g., "What is the capital of France?").
  • low_reasoning: For tasks requiring basic arithmetic, comparisons, or single logical steps (e.g., "If John has 5 apples and eats 2, how many are left?").
  • high_reasoning: For complex problems demanding multi-step logic or deep problem-solving (e.g., "Prove that the sum of two even numbers is always even").
• Efficient Task Routing: Enables intelligent distribution of queries to appropriate downstream models or systems based on their identified reasoning requirements.

Good for

• Orchestrating LLM Workflows: Ideal for developers building systems that need to route user queries to different specialized LLMs (e.g., a factual QA model, a mathematical solver, or a complex reasoning engine).
• Optimizing Resource Usage: By pre-classifying queries, it helps ensure that computationally intensive models are only engaged for high-reasoning tasks, improving overall efficiency.
• Building Intelligent Agents: Useful for creating agents that can dynamically adapt their approach based on the complexity of the user's request.
