# Fine-tuning

> Fine-tune a model to write in a style

## Basics

Fine-tuning will create an AI model that matches a writing style. The fine-tuning endpoint requires specifying one or more files to use to train the AI. You can use as many files as you want.

For best results:

1. Use files with a consistent style
2. Use files of the same type that you want to style, e.g. fine-tuning on product guides will create a model that works best on product guides

The `model` is the model to fine-tune (currently `vaero-2`)

The response will include a fine-tuned model ID, which you will use to identify the model for inference.

Fine-tuning can sometimes complete in a few hours, but may take up to 24 hours based on load. The status of the job will change from 'queued' to 'completed' when finished.
