The big idea
GPT-4o-mini is OpenAI's small, cheap model. It's smart enough for most everyday tasks and costs pennies per million tokens. Devs use it for chatbots, summaries, and classification at scale.
Some examples
- Power a class assistant bot with 4o-mini and barely spend a dollar.
- Use it to classify thousands of emails into categories cheaply.
- Skip it when you need careful reasoning — go to GPT-5.
- It's multimodal too: can read images, just not as well as GPT-5.
Try it!
If you build something with the OpenAI API, start with 4o-mini. Only upgrade if quality isn't good enough.
