# Open Source AI: Why the Skeptics are Wrong

For anyone actually building an AI workflow, the ability to self-host a model means you aren't at the mercy of a third-party API changing its behavior overnight or hiking prices. If you're running a local Llama 3 or Mistral instance, you have total control over the system prompt and the sampling parameters without a middleware layer filtering your inputs.

If you want to move away from proprietary silos, here is a basic deployment path for a local LLM agent using Ollama, which is the most beginner-friendly way to start:

1. Install Ollama on your machine.

2. Pull the model you want to test:

```
ollama run llama3
```

3. Connect it to your local IDE or a tool like Open WebUI to start building your own RAG pipeline.The real-world advantage here is the deep dive into the weights and the ability to fine-tune on proprietary data without sending that data to a cloud server. The "safety" argument falls apart when you realize that the most innovative prompt engineering and optimization techniques almost always emerge from the open community first.
