🧠 Understanding AI in 2025: How It Works, Grows, and Runs Locally with Ollama

Artificial Intelligence (AI) has grown into an essential part of our world. In 2025, it powers everything from smart assistants to self-writing code. But how does it really work? How is it evolving? And how can you run powerful AI on your own device, completely offline, using tools like Ollama?

🔍 How AI Works

AI models are trained to understand and generate language, images, and more. Here’s how it breaks down:

  • Training: Models are fed massive datasets to learn patterns.
  • Inference: Once trained, models can answer questions, generate ideas, or summarize text.
  • Fine-tuning: Developers customize models to specific domains—like legal, medical, or education.

📈 AI Growth in 2025

Here’s what’s new this year:

  • Edge AI: Models now run offline on laptops and phones.
  • Open-source Booms: Tools like llama3, mistral, and gemma are free and local.
  • Multimodal Magic: AI can now process text + image + audio together.
  • AI Agents: Custom bots that plan, browse, reply—on their own.
