Phi-4-Mini-Reasoning (GGUF Q4_KM) - Sandlogic Lexicons

Model Summary

Phi-4-Mini-Reasoning is a lightweight open-source model from the Phi-4 family, designed with a strong focus on high-quality, reasoning-dense synthetic data. It has been further fine-tuned for advanced mathematical reasoning tasks and supports a 128K token context length. This model is especially optimized for logic-intensive scenarios while maintaining a compact size, making it ideal for memory and compute-constrained environments.

Model Family: Phi-4
Parameter Count: 3.8B
Architecture: Dense decoder-only Transformer
Context Length: 128K tokens
Quantization: GGUF Q4_KM

Intended Uses

Primary Use Cases

Phi-4-Mini-Reasoning is designed to excel at:

Multi-step mathematical reasoning
Formal proof generation
Symbolic computation
Solving advanced word problems
Tasks requiring structured logic and analytical thinking

Its high context length and reasoning capabilities make it suitable for latency-bound applications and deployments on resource-constrained hardware.

Use Case Considerations

This model is optimized specifically for mathematical reasoning tasks.
It is not evaluated for general-purpose downstream tasks such as conversational AI or creative writing.
Developers should:
- Assess use case suitability.
- Account for limitations in multi-language support.
- Evaluate performance, safety, and fairness—especially in high-risk or regulated environments.
- Ensure compliance with all applicable laws and regulations (e.g., privacy and trade compliance).
