+## Sarcastic Bot
+
+This use case demonstrates how the OpenAI Fine-tunes API v1 can be harnessed to fine-tune the GPT-3.5-turbo model to produce sarcastic responses. The example showcases a series of steps that utilize the OpenAI Files API v1 to upload training data, followed by using the OpenAI Fine-tunes API v1 to fine-tune the GPT-3.5-turbo model with that data, getting the traning model events.

The example outlines a series of steps that include using the OpenAI Files API v1 to upload training data, then employing the OpenAI Fine-tunes API v1 to fine-tune the GPT-4o-mini model with this data, and finally printing the model's checkpoints and deleting the data file.
