Section 1 - Instruction

You've learned about AI models and applications. But how do the big names like ChatGPT, Gemini, and Claude actually fit together?

Each major AI assistant runs on specific "engine" models, and understanding this ecosystem helps you choose the right tool.

ChatGPT, made by OpenAI, is probably the most famous. But here's the secret - it's powered by different versions of GPT models!

GPT-3.5, GPT-4, and newer versions like GPT-4o are the actual "brains" inside. ChatGPT is just the friendly interface wrapped around them.

Did you know ChatGPT can switch between different GPT versions?

Section 3 - Instruction

Google's Gemini (formerly Bard) works the same way. It's powered by Google's own model family - also called Gemini!

They have Nano (for phones), Pro (balanced power), Ultra (maximum capability), and Flash (super fast). Each serves different purposes.

Have you noticed Gemini integrated into Google Docs or Gmail?

Section 4 - Instruction

Claude, created by Anthropic, follows a poetic naming pattern. Its models are Haiku (fast and light), Sonnet (balanced), and Opus (most powerful).

Claude is known for being helpful and handling very long documents - up to 200,000 words!

What would you use an AI for - quick tasks or deep analysis?

Section 5 - Instruction

Here's something cool - these companies can upgrade the "engine" without changing the app!

ChatGPT might upgrade from GPT-4 to GPT-4.5, keeping the same chat interface. Most of the time the tools have a dropdown that let's you switch the model.

Why might this flexibility be valuable for users?
