+ +## Overview + +**`qwen2.5-3b-claude-distilled-reasoning-dpo`** is a post-trained, reasoning-specialized 3.0B parameter causal language model. + +This model represents a two-stage post-training alignment pipeline built on top of `Qwen/Qwen2.5-3B-Instruct`: + +1. **Supervised Fine-Tuning (SFT):** Fine-tuned on high-quality internal reasoning monologue traces distilled from **Claude 3.5 Sonnet**, imparting deep step-by-step mathematical, logical, and code-synthesis reasoning behavior. +2. **Direct Preference Optimization (DPO):** Aligned using `DPOTrainer` on preference pairs (`argilla/ultrafeedback-binarized-preferences-cleaned`). This step eliminates scientific hallucinations (e.g., density vs. thermal conductivity), suppresses infinite token repetition loops, and anchors physical explanations to first-principles facts. + +--- + +## Model Capabilities & Highlights + +* **Distilled Chain-of-Thought (CoT):** Thinks through mathematical equations, coding challenges, and logic puzzles step-by-step prior to executing answers. +* **Factually Grounded:** High performance on graduate/research-level physics and mathematics questions, reducing hallucination tendencies present in basic SFT models. +* **ChatML Ready:** Fully compatible with standard Qwen2.5 ChatML chat templates and system prompt instructions. +* **Low Memory Footprint:** Runs comfortably in FP16/SDPA on a single consumer GPU (e.g., NVIDIA T4 / RTX 3060) requiring ~6GB VRAM. + +--- + +## Alignment & Evaluation Pipeline + +| Feature | Base Model (`Qwen2.5-3B-Instruct`) | SFT Stage (`...-reasoning`) | DPO Stage (`...-reasoning-dpo`) | +| :--- | :--- | :--- | :--- | +| **Reasoning Engine** | Static response generation | Claude CoT monologue traces | **Refined CoT monologue traces** | +| **Physics/Math Accuracy** | Standard textbook baseline | Prone to reasoning hallucinations | **First-principles verified** | +| **Degeneracy / Loops** | Standard EOS handling | Prone to trailing follow-up loops | **Suppressed via preference rewards** | + +--- + +## Integrated Real-Time Streaming & Safe Inference Script + +The code below provides a production-ready, bulletproof inference script. It includes: +* **Token-by-Token Streaming** using `TextIteratorStreamer`. +* **Dynamic Temperature Scaling** (lowers temperature for simple greetings to prevent creative rambling; elevates it for math/reasoning tasks). +* **System Prompt Injection** to prevent tool/interface hallucinations. +* **Custom Stopping Criteria** to cut off any potential ASCII symbol artifacts or trailing conversational chatter. + +```python +import os +import sys +from threading import Thread +import torch +import time +from transformers import ( + AutoTokenizer, + AutoModelForCausalLM, + TextIteratorStreamer, + StoppingCriteria, + StoppingCriteriaList +) + +# ========================================================================= +# 1.
