Connect to Your Goldspot
Local Network (SSH)
When you're on the same WiFi/LAN as the Goldspot:
SSH key auth is configured — no password needed from your Mac.
By IP Address
If mDNS doesn't work, check your router's admin page for the Goldspot's IP, then:
ssh pi@<your-goldspot-ip>
Via Tailscale (from anywhere)
After setting up Tailscale:
Local AI: Qwen 3.5
A fully local, private AI model running on the Goldspot via Ollama. No internet or API keys needed for inference — everything runs on-device.
Run It
From your Mac, one command to start chatting:
# Interactive chat
ssh pi@goldspot.local -t "ollama run qwen3.5:4b"
# Or SSH in first, then run
ssh pi@goldspot.local
ollama run qwen3.5:4b
Type your prompt and press Enter. Type /bye to exit.
What to Expect
!
Speed: Expect ~2-5 tokens/sec on the Pi 4 CPU. Responses will stream in slowly but steadily. Good for code review, writing, and analysis — not for real-time chat.
!
First run: The first prompt takes ~15-30 seconds to load the model into RAM. Subsequent prompts in the same session are faster.
!
Quality: Qwen 3.5 4B punches above its weight — tool calling, reasoning, and vision built in. Comparable to much larger models from a year ago.
Use as an API
Ollama exposes an OpenAI-compatible API locally. From the Goldspot itself:
# Local API call
curl http://localhost:11434/api/generate \
-d '{"model":"qwen3.5:4b","prompt":"hello"}'
Works with any OpenAI-compatible client. Access from other devices via SSH tunnel or Tailscale.
Manage Models
ollama list # Installed models
ollama pull qwen3.5:0.8b # Faster, lighter
ollama pull qwen3.5:9b # Smarter, uses ~7GB RAM
ollama rm qwen3.5:4b # Remove a model
ollama ps # Running models
Remote Access with Tailscale
Tailscale creates a private VPN so you can access your Goldspot from anywhere — phone, laptop, coffee shop, anywhere.
Activate Tailscale
1
On the Goldspot, run:
sudo tailscale up
2
It will print a URL — open it in your browser and log in with Google/GitHub/etc.
3
Install Tailscale on your Mac too:
brew install --cask tailscale
4
Now connect from anywhere:
ssh pi@goldspot
Enable SSH via Tailscale (optional)
Let Tailscale handle SSH auth (no passwords needed):
sudo tailscale up --ssh
