Windows AI — Local AI on Your Windows PCs

Run AI entirely on Windows. No cloud APIs, no subscriptions, no data leaving your network. Windows AI via Ollama Herd routes LLM requests across your Windows machines — your gaming PC, your work desktop, your laptop. One Windows AI endpoint serves them all.

Why Windows AI locally

• Zero cost — no per-token charges. Your Windows PC runs unlimited AI inference.
• Privacy — prompts and responses never leave your Windows network.
• No rate limits — cloud APIs throttle. Your Windows AI hardware doesn't.
• NVIDIA GPU support — Windows AI uses your RTX GPU via CUDA for fast inference.
• Fleet routing — multiple Windows PCs share the AI workload automatically.

Windows AI quick start

# Install Windows AI router
pip install ollama-herd

# Start Windows AI on your main PC
herd          # Windows AI router on port 11435
herd-node     # register this Windows AI node

# On other Windows PCs
herd-node     # joins the Windows AI cluster automatically

Windows Firewall: Allow port 11435 — netsh advfirewall firewall add rule name="Windows AI" dir=in action=allow protocol=tcp localport=11435

Use Windows AI

OpenAI SDK

from openai import OpenAI

# Your Windows AI endpoint
client = OpenAI(base_url="http://localhost:11435/v1", api_key="not-needed")

# Windows AI routes to the best available GPU
response = client.chat.completions.create(
    model="qwen3.5:32b",
    messages=[{"role": "user", "content": "Explain local AI vs cloud AI for Windows users"}],
    stream=True,
)
for chunk in response:
    print(chunk.choices[0].delta.content or "", end="")

Windows AI for coding

# Windows AI code generation
response = client.chat.completions.create(
    model="codestral",
    messages=[{"role": "user", "content": "Write a C# Windows service that monitors GPU temperature"}],
)
print(response.choices[0].message.content)

curl (PowerShell)

# Windows AI chat
curl http://localhost:11435/api/chat -d '{
  "model": "llama3.3:70b",
  "messages": [{"role": "user", "content": "Hello from Windows AI"}],
  "stream": false
}'

Windows AI hardware guide

Windows AI works with or without a GPU. NVIDIA GPUs dramatically accelerate inference.

Windows AI environment setup

# Optimize Windows AI performance
[System.Environment]::SetEnvironmentVariable("OLLAMA_KEEP_ALIVE", "-1", "User")
[System.Environment]::SetEnvironmentVariable("OLLAMA_MAX_LOADED_MODELS", "-1", "User")
# Restart Ollama from the Windows system tray

Windows AI features

• 7-signal scoring — picks the best Windows PC for every AI request
• 15 health checks — monitors all Windows AI nodes in real-time
• Auto-retry — transparent failover between Windows AI machines
• vRAM-aware routing — knows which Windows GPU has room for the model
• Request tagging — track per-project Windows AI usage
• Web dashboard — http://localhost:11435/dashboard

Windows AI integrations

Works with any OpenAI-compatible tool on Windows:

• Continue.dev (VS Code) — set endpoint to http://localhost:11435/v1
• Cursor — Windows AI as local backend
• LangChain — drop-in OpenAI replacement
• CrewAI — multi-agent workflows on Windows AI
• Open WebUI — chat interface for Windows AI
