This introduces the llama-3-2-3b-reasoning-sft-neo project, which distills DeepSeek-R1-style chain-of-thought reasoning capabilities into the Llama-3.2-3B model using Unsloth SFT and LoRA technologies. The final model is exported in GGUF format (only 2GB) and can run on low-resource devices like mobile phones or Raspberry Pi.

This introduces the llama-3-2-3b-reasoning-sft-neo project, which distills DeepSeek-R1-style chain-of-thought reasoning capabilities into the Llama-3.2-3B model using Unsloth SFT and LoRA technologies. The final model is exported in GGUF format (only 2GB) and can run on 4GB devices like mobile phones or Raspberry Pi, bridging the technical gap in edge-side reasoning models.
Section 02
Reasoning models represented by DeepSeek-R1 and OpenAI o1 have strong performance but high resource requirements, making edge-side deployment difficult. Lightweight models (e.g., Llama-3.2-3B) can run on edge devices but lack systematic reasoning capabilities, creating a technical gap. This project aims to bridge this gap.
Section 03
The core goal is to enable Llama-3.2-3B-Instruct to generate DeepSeek-R1-style reasoning traces and export a 2GB GGUF model. Technical selection: Base model is Llama-3.2-3B-Instruct (cost-effective, 2GB after quantization); fine-tuning framework uses Unsloth SFT (reduces memory requirements); parameter-efficient fine-tuning uses LoRA (r=16, alpha=32); training strategy adopts Response-Only Training (only learns to generate the response part).
Section 04
Dataset construction: 500 samples, including problem descriptions, reasoning processes, and final answers, drawing on the DeepSeek-R1 paradigm. Response-Only Training mechanism: Masks the input prefix, only calculates the loss of the response part, focusing on generating reasoning traces. LoRA configuration optimization: r=16 balances expressive power and parameter count, alpha=32 provides a moderate adjustment range.
Section 05
After fine-tuning, the model is converted to GGUF format (Q4_K_M quantization), with a file size of approximately 2GB. Deployment scenarios: Mobile phones (8GB+ memory, local operation protects privacy), Raspberry Pi 5 (8GB version, edge AI applications), embedded systems (ARM architecture, IoT intelligent decision-making).
Section 06
Filling capability gaps: The original Llama-3.2-3B performs poorly on multi-step tasks; this project endows it with reasoning capabilities. Lowering the threshold: Provides a complete scripted workflow (trainer.py, export.py), data validation tools, and clear dependency management, allowing ordinary users to reproduce without an A100.
Section 07
Edge-side AI advancements: Local operation protects privacy, low latency, offline availability, and cost reduction. Educational and research value: Demonstrates the application of technologies like LoRA and provides a complete pipeline reference. Potential scenarios: Intelligent education assistants, offline programming assistants, industrial quality inspection, smart home hubs.
Section 08
Limitations: Small data scale (only 500 samples), limited reasoning depth (weaker than DeepSeek-R1), insufficient domain generalization. Improvement directions: Expand the dataset, explore edge-side deployment of larger models, develop domain-specific versions, and optimize reasoning speed.
