Run Generative AI models on your Laptop with Ollama

Since OpenAI released ChatGPT, there's been a surge of interest in generative AI (GenAI). These powerful models can write different kinds of creative text formats, translate languages, write different kinds of creative content, and answer your questions in an informative way. However using them often requires cloud access, which can raise security or privacy concerns.

This blog post explores how to run GenAI models locally on your machine using Ollama, an open-source platform from Meta.

What is Ollama?

Ollama is a user-friendly platform that allows you to download and run various large language models (LLMs) on your workstation. These models include Llama 3.1, Phi, Minstrel, and Gemma.

Why Run GenAI Models Locally?

There are several reasons why you might want to run GenAI models locally:

• Security: If you're working with sensitive data, you might prefer not to upload it to the cloud.
• Privacy: You might be concerned about your data being accessed by third parties.
• Cost: Running models locally can be more cost-effective than using cloud-based services.
• Offline Use: You can use GenAI models even without an internet connection.
