Run OpenAI’s GPT-OSS Models Locally with Ollama

Ever wished you could run a powerful GPT model right on your own laptop, totally offline and for free? I always thought you’d need some crazy supercomputer, but I just saw a video from an AI professional that completely changes the game.

OpenAI has finally released new open-weight models, called GPT-OSS, and this YouTuber walks through exactly how to get them running locally. This is huge for anyone who wants more privacy, speed, and control over their AI.

✨ The Two New Models

The creator explains that there are two versions available:

• GPT-OSS 20B: A 20-billion parameter model that can run on a high-end laptop. The expert demonstrates this one running smoothly on their M3 Max laptop.
• GPT-OSS 120B: A massive 120-billion parameter model that needs a seriously powerful desktop PC to run.

⚙️ How to Install It (The Easy Way)

I was blown away by how simple this is. The video’s creator recommends using a free app called Ollama, and the process is dead simple. You don’t even need to open the terminal!

Here’s the method the expert shared:

1. 📌 Go to the Ollama website and download the free app for Mac, Windows, or Linux.
2. ✅ Once it’s installed, open the app. You’ll see a dropdown menu with available models.
3. 🚀 Select the new GPT-OSS model right at the top.
4. 💡 Type your first message and hit send. The app will automatically download the model (it’s about 12-13 GB) in the background. That’s it!

You’re now running an OpenAI model locally on your own machine. The person who shared it showed that the responses were almost instant, which is way faster than the web demo.

This innovator also mentions another tool called LM Studio, which works but is a bit more technical. For pure simplicity, Ollama seems to be the clear winner.

I think this is a massive step forward, making powerful AI more accessible to everyone. The way this industry pro broke it down makes it feel possible for anyone with a decent computer.
