GPT-4o vs Claude 3.5 vs Gemini — Which LLM Should You Use?

AI is evolving fast.
But choosing the right model is what actually drives results.

GPT-4o, Claude 3.5, and Gemini are three of the most powerful LLMs available today — but each one is built differently.

What Are LLMs?

Large Language Models (LLMs) are AI systems that:

• Understand and generate text
• Assist with coding, writing, and analysis
• Power chatbots, agents, and automation

👉 They are the brains behind modern AI systems
