Local Swarm

Run a swarm of local LLMs on your hardware. Multiple models work together to give you the best answer through consensus voting.

What It Does

• Auto-detects your hardware (NVIDIA, AMD, Intel, Apple Silicon, Qualcomm, or CPU)
• Downloads and runs multiple LLM instances optimized for your VRAM/RAM
• Uses consensus voting - all instances answer, best response wins
• Connects multiple machines on your network for a "hive mind" effect
• Provides an OpenAI-compatible API at http://localhost:17615/v1

Quick Start

# Clone and install
git clone https://github.com/yourusername/local_swarm.git
cd local_swarm
pip install -r requirements.txt

# Run it
python main.py

On first run, it will:

1. Detect your hardware
2. Pick the best model and quantization
3. Download the model (one-time)
4. Start multiple LLM workers
5. Expose the API at http://localhost:17615

Usage

Interactive Mode (default)

python main.py

Shows a menu with:

• Recommended configuration (auto-selected)
• Browse all compatible models
• Custom configuration wizard

Auto Mode (no menu)

python main.py --auto

With Other Options

python main.py --model qwen:3b:q4      # Use specific model
python main.py --instances 4           # Force 4 workers
python main.py --port 8080             # Custom port
python main.py --detect                # Show hardware info only
python main.py --federation            # Enable network federation
python main.py --mcp                   # Enable MCP server
python main.py --use-opencode-tools    # Use opencode tools (adds ~27k tokens)

Tool Mode Options:

• Default: Local tool server (~125 tokens, saves context window space)
• --use-opencode-tools: Full opencode tool definitions (~27k tokens, more capabilities)

Connect to Opencode

Add to your opencode config:

{
  "model": {
    "provider": "openai",
    "base_url": "http://localhost:17615/v1",
    "api_key": "not-needed",
    "model": "local-swarm"
  }
}

Network Federation (Hive Mind)

Run on multiple machines to combine their power:

# Machine 1 (Windows with RTX 4060)
python main.py --auto --federation

# Machine 2 (Mac Mini M1)
python main.py --auto --federation

# Machine 3 (Old laptop)
python main.py --auto --federation

Machines auto-discover each other and vote together on every request.

How Consensus Works

1. Your prompt goes to all LLM instances
2. Each instance generates a response independently
3. The consensus algorithm picks the best answer:
   • Similarity (default): Groups responses by meaning, picks the largest group
   • Quality: Scores on completeness, code blocks, structure
   • Fastest: Returns the quickest response
   • Majority: Simple text match voting

Configuration

Create config.yaml:

server:
  host: "127.0.0.1"
  port: 17615

swarm:
  consensus_strategy: "similarity"  # similarity, quality, fastest, majority
  min_instances: 2
  max_instances: 8

federation:
  enabled: true
  discovery_port: 8765
  max_peers: 10

Supported Hardware

Hardware	Backend	Notes
NVIDIA GPU	llama.cpp (CUDA)	Best performance
AMD GPU	llama.cpp (ROCm)	Linux/Windows
Intel GPU	llama.cpp (SYCL)	Linux/Windows
Apple Silicon	MLX	Native Metal
Qualcomm	llama.cpp (CPU)	Android/Termux
CPU-only	llama.cpp	Slower but works

Supported Models

• Qwen 2.5 Coder (3B, 7B, 14B) - Recommended
• DeepSeek Coder (1.3B, 6.7B, 33B)
• CodeLlama (7B, 13B, 34B)

All support GGUF quantization (Q4_K_M recommended).

API Endpoints

• GET /v1/models - List available models
• POST /v1/chat/completions - Chat completion with consensus
• GET /health - Health check
• GET /v1/federation/peers - List discovered peers (when federation enabled)

Troubleshooting

Out of Memory

python main.py --instances 2           # Reduce workers
python main.py --model qwen:3b:q4      # Use smaller model

Slow Performance

• Check GPU utilization with nvidia-smi
• Reduce instances to avoid contention
• Use Q4 quantization instead of Q6

CUDA Not Detected (Windows)

nvidia-smi  # Check drivers
pip uninstall llama-cpp-python
pip install llama-cpp-python --extra-index-url https://abetlen.github.io/llama-cpp-python/whl/cu121

macOS: MLX Not Found

pip install mlx-lm

Architecture Principles

• Modular Design: Each module has a single, focused responsibility
• Configuration Over Code: Static data extracted to JSON config files
• Separation of Concerns: API, CLI, and business logic are cleanly separated
• No Files > 300 Lines: Most modules kept under 300 lines for maintainability

Development

• Function Size: No functions > 50 lines
• Nesting Depth: No indentation > 3 levels
• DRY Principle: No duplicate code (>3 lines)
• Single Responsibility: Each module does one thing
• Configuration Over Code: Static data in JSON configs

Recent Refactoring

Major refactoring completed to improve modularity:

Before: Monolithic files (main.py: 556 lines, routes.py: 1,183 lines) After: Modular architecture (main.py: 99 lines, routes.py: 252 lines)

Changes:

• Extracted API logic into focused modules (formatting, parsing, handlers)
• Created CLI package with separated concerns (parser, runner, server)
• Moved hardcoded model data to JSON configuration files
• Created shared utility modules (token_counter, project_discovery, network)
• Reduced code duplication across the codebase
