AI Tools
A step-by-step guide to downloading and installing Ollama to run AI reasoning models locally on your computer without an internet connection.
Storage & Internet Requirements
The GPT-OSS-20B model has a large file size (around 13GB). Ensure you have sufficient storage space and a stable internet connection for the initial download process.
Real-Time Performance
Since this model runs locally, the speed of 'prompt completion' depends entirely on your computer's hardware power. Reasoning models are generally slower than standard chat models because they perform deep cognitive processing.
Privacy & Offline Usage
The primary advantage of using Ollama is data privacy. Once the model is fully downloaded, you can disconnect from the internet, and the AI will still remain fully functional offline.
