Sure, for running an LLM locally on an iOS device, we can use a smaller, more efficient model like GPT-2 or a distilled version. For simplicity, I will demonstrate using the CoreML framework with a pre-trained GPT-2 model that has been converted to CoreML format. This example will include the necessary steps to integrate the model and measure the response time.

1. Convert a Pre-trained GPT-2 Model to CoreML

First, you need to convert a pre-trained GPT-2 model to CoreML format. This is typically done outside Xcode using a Python script. Here is a basic script to convert a GPT-2 model to CoreML:
