🧠 MiniCPM5-2B Local Hybrid AI

A lightweight python application leveraging OpenBMB's MiniCPM5-2B model via Hugging Face transformers to execute hybrid dual-brain reasoning (Fast No-Think answers vs Deep Think reasoning) on large context input files under 4GB VRAM.

⚡ 3-Step Workflow

Step 1: Input	Step 2: AI Action	Step 3: Result
Reads context file from inputs/large_context.txt	MiniCPM5-2B runs Fast Mode & Deep Think Mode benchmarks	Calculates generation time, TPS, and extracts <think> reasoning data

🚀 Key Superpowers

• Dual-Brain Hybrid Engine: Toggle between instant fast response ("No-Think") for simple routing and deep step-by-step reasoning ("Think") for complex logic from a single model checkpoint.
• Ultra-Low Hardware Footprint: Fits inside 4GB VRAM on standard consumer GPUs without sacrificing intelligence.
• 128K Massive Context Window: Natively ingests entire long-form transcripts, codebases, and massive text files locally from inputs/.
• Local Model Storage: Saves model weights inside the models/ subfolder for 100% offline local inference.
• #1 Leader Under 4B: Outperforms competing models up to 12B parameters on the Artificial Analysis Intelligence Index.

📦 Quickstart & Model Download

Run these single-step PowerShell commands to install dependencies and download the MiniCPM5-2B model checkpoint directly into the models/ subfolder:

# Install PyTorch, Hugging Face transformers, and download tool
pip install torch transformers accelerate huggingface_hub

# Download MiniCPM5-2B model checkpoint into models/ subfolder
huggingface-cli download openbmb/MiniCPM5-2B --local-dir models/MiniCPM5-2B

💻 Running Context Benchmark Testing

Place your target text file in inputs/large_context.txt and execute the benchmark:

python main.py

The script will auto-detect the local model in models/MiniCPM5-2B, execute queries across both Fast and Deep Thinking modes, measure tokens/second (TPS) performance, extract thinking steps, and save a full evaluation report to outputs/outputs.md.

🎯 5 Practical Use Cases

1. Large Context Transcript QA: Feeds multi-page text documents from inputs/ into the model to extract facts and verify claims.
2. Local Desktop Automation Router: Fast "No-Think" mode categorizes incoming requests in milliseconds, triggering local script executions.
3. Privacy-First Code Auditor: Ingests multi-file code repositories entirely offline on local PC hardware without sending data to external APIs.
4. Offline Academic Assistant: Uses "Think" mode to solve multi-step mathematical proofs and logical puzzles with explicit chain-of-thought steps.
5. Low-Latency Edge Assistant: Runs on low-power edge devices and laptops with under 4GB VRAM for real-time field operations.

🔮 5 Future Enhancement Features

1. GGUF & Ollama Integration: Register quantized GGUF weights for native local CLI serving via Ollama.
2. Streamlit Interactive UI: Build a responsive visual web dashboard with real-time thinking process toggles.
3. Structured JSON Output Parser: Add Pydantic schema validation for strict JSON response outputs.
4. Multi-Turn Chat Terminal: Implement interactive multi-turn conversation memory with dynamic thinking parameters.
5. Local RAG Integration: Pair MiniCPM5-2B with local vector stores for hybrid retrieval and deep document reasoning.
