Zweek Code

AI Coding Assistant That Runs on YOUR Machine
No cloud. No telemetry. Just you and your code.

What Is This?

A terminal-based AI coding assistant powered by specialized local models. Unlike cloud assistants, everything runs offline on consumer hardware using optimized small models (135M-1.1B parameters).

Philosophy: Use deterministic tools when possible, AI when necessary.

Features

✅ 100% Offline – No internet, no tracking, no data leaves your machine
✅ Fast – Router stays resident (~150MB RAM), responses in seconds
✅ Private – Your code is yours
✅ Lightweight – Runs on older hardware (4GB RAM minimum)
✅ Smart Routing – SmolLM classifies intent (CODE/CHAT/TOOL) instantly

Architecture

Optimized 3-Model System:

1. Router (SmolLM-135M) - Stays loaded, classifies intent with GBNF grammar
2. Code Drafter (StarCoder-Tiny) - Generates code when needed
3. Chat (Qwen3-0.6B-Q8_0) - Answers questions about your code

Key Optimizations:

• Resident models stay in memory (~350MB idle)
• GBNF grammars eliminate hallucination
• Compiler check (cl.exe) validates code instantly (no AI)
• Peak RAM: ~500MB during inference

Quick Start

Requirements

• Windows 10/11, Linux, or macOS
• 4GB RAM minimum (8GB recommended)
• CMake 3.20+
• C++17 compiler

Build

git clone https://github.com/wedsmoker/zweek-code.git
cd zweek-code

# Download models (place in models/ directory)
# - smollm-135m-router.gguf
# - Qwen3-0.6B-Q8_0.gguf  
# - starcoder-tiny.gguf

cmake -S . -B build -G Ninja
cmake --build build
.\build\zweek.exe  # Windows
./build/zweek      # Linux/macOS

See QUICKSTART.md for detailed instructions.

Models

Place these in models/:

Model	Size	Purpose	RAM
smollm-135m-router.gguf	~150MB	Intent classification	Resident
starcoder-tiny.gguf	~200MB	Code generation	On-demand
Qwen3-0.6B-Q8_0.gguf	~700MB	Q&A	On-demand

Download from HuggingFace (GGUF Q8 quantized versions).

Performance

Target: <15 seconds for most operations
Idle RAM: ~350MB (Router + Code Drafter resident)
Peak RAM: ~500MB during chat inference
