In 2025, artificial intelligence is growing faster than ever. This year is an important turning point, where people and businesses are deciding between using AI in the cloud or running it directly on their own devices. In this blog, we’ll look at two major players—Ollama and OpenAI—and see how House of FOSS is helping make powerful open-source AI tools easy and affordable for everyone.
AI today is full of new possibilities, especially with Large Language
Models (LLMs). More people want AI that runs on their own devices instead of relying on the cloud. This change isn’t just about technology—it’s about giving you more control, privacy, and lower costs.
In this fast-changing world, Ollama and OpenAI are leading the way. OpenAI is known for its powerful cloud-based models, while Ollama is making it easier to run LLMs locally. Let’s dive in and see how these platforms are shaping the future of AI.
