  "textContent": "The mini models are almost always less capable because they have significantly lower precision. The trade-off is speed and price.\n\nI personally find the nano models unusable for my use cases for this very reason. Mini models can be a good compromise for certain purposes and you will have to make that judgement for yourself.\n\nFor my personal chatbot tasks I use the full size frontier models. It saves tokens in the end of the day because the model is more likely to one shot.\n\nSame goes for many production tasks. I don’t want to have to review and rerun things because a smaller model failed.",
