AI model guide

Comparing AI models,
without the computer science degree.

There are hundreds of AI models out there. Most comparisons are made for engineers. This one is made for everyone else - what's each model actually good at, how fast is it, and what will it cost you?

🤔

What even is an AI model?

Think of it like a brain you can rent. Different brains are better at different things - some are faster, some are smarter, some are cheaper. You send it a question, it sends back an answer.

💸

Why does cost vary so much?

More capable models cost more to run. A model that can reason through a hard problem like a PhD takes more compute than one answering simple questions. You pay for what you get.

🎯

Which one should I use?

It depends what you need. Writing? Claude Sonnet or GPT-4o. Hard math? o3 or DeepSeek R1. Research with real sources? Perplexity Sonar. Budget-conscious? DeepSeek V3 or Llama.
