ChatGPT

Model (ChatGPT)

The trained system that produces ChatGPT's answers. You pick how hard it thinks with the thinking level, not by learning model names.

You set the level, the model does the work You pick a thinking level, ChatGPT routes to the right model, and you get an answer: faster on Instant, more thorough higher up. Your question any task Thinking level Instant to Pro The model engine inside Your answer fast or thorough Learn the dial, not the model names.

The model is the engine behind ChatGPT's answers. OpenAI releases new ones often (at the time of writing, GPT-6), and the names change faster than the way you use them.

In ChatGPT you mostly choose a thinking level: Instant for everyday work, higher levels for harder problems. Work and Codex can use some models that plain Chat doesn't. On Business, admins may limit which models are available.

Often confused with: The app. ChatGPT is the product you use; the model is the engine inside it, and it gets swapped out over time.
