šŸ¤” Windows + WSL2 + Ollama - which architecture should I use?

I’m setting up a local AI development environment on Windows + WSL2 and I’m trying to decide between two architectures.

Option 1 — Ollama/Models on Windows

        WSL2

Option 2 — Ollama/Models inside WSL2

          WSL2
ā”Œā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”

│           ↓             │
│         Ollama          │
│           ↓             │
│         Models          │
ā””ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”¬ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”˜

             │

          Windows
ā”Œā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”
│      GPU / Driver       │
ā””ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”˜

My current setup is Option 1, and it works: WSL2 can access the Windows Ollama API through localhost:11434.

But I’m wondering if Option 2 is a better long-term architecture for local AI/LLM development.

I’m especially interested in:

šŸš€ Performance
šŸŽ® GPU utilization
🧠 Model management
šŸ’¾ Disk usage
šŸ”§ Setup and maintenance
🐧 Linux/ML tooling
🐳 Docker integration
🌐 Networking
šŸ“ˆ Future scalability

If you use Ollama with Windows + WSL2, which architecture would you choose and why?

And if you've actually used both setups, I'd especially like to hear about your experience.

šŸ‘‡ Option 1 or Option 2?
