AI model families: GPT-5 and what's new

GPT-5 is OpenAI's flagship model. It's smarter at reasoning, handles longer documents, and is better at code. Knowing what version you're using matters because answers differ.

Some examples

• Use GPT-5 for hard reasoning tasks
• Notice GPT-5's better code than GPT-4
• Compare GPT-5 vs GPT-4 on the same prompt
• Check which model your tool actually uses

Try it!

Find a hard math or logic question. Ask it to GPT-4 and GPT-5 (if you have access). Note where the answers differ. Even if both right, the explanations vary.

Practice this safely

Try this with a school, hobby, or family example where the stakes are low. Use the AI output as a draft you can question, not as the final answer.

1. 1Ask AI to explain gpt-5 in plain language, then underline anything that sounds uncertain or too broad.
2. 2Give it one detail from "AI model families: GPT-5 and what's new" and ask for two possible next steps plus one reason each step might be wrong.
3. 3Check openai against a trusted source, teacher, adult, expert, or original document before you use it.
