-This example gives the prompts you can enter into {% data variables.product.prodname_copilot_chat_short %} to complete the migration, and the responses {% data variables.product.prodname_copilot_short %} returned for one instance of this migration. {% data variables.product.prodname_copilot_chat_short %} responses are non-deterministic, so you will probably get slightly different responses to the ones shown here.
+This example gives the prompts you can enter into {% data variables.product.prodname_copilot_chat_short %} to complete the migration, and the responses {% data variables.product.prodname_copilot_short %} returned for one instance of this migration. The default GPT 4o model was used to generate these responses. {% data variables.product.prodname_copilot_chat_short %} responses are non-deterministic, so you will probably get slightly different responses to the ones shown here.
 
 During a migration process you are likely to get errors that you need to fix before moving ahead. {% data variables.product.prodname_copilot_short %} can help you with this. The example includes some errors and shows how you can get {% data variables.product.prodname_copilot_short %} to help you fix them.

-{% data variables.product.prodname_copilot_chat_short %} uses the GPT 4o model by default. Depending on the task you are working on, you may want to use a different model, such as the {% data variables.copilot.copilot_claude_sonnet %} model or the o1 model.

 The following models are currently available through multi-model {% data variables.product.prodname_copilot_chat_short %}:
 
 * **GPT 4o:** This is the default {% data variables.product.prodname_copilot_chat_short %} model. It is a versatile, multimodal model that excels in both text and image processing and is designed to provide fast, reliable responses. It also has superior performance in non-English languages. Learn more about the [model's capabilities](https://platform.openai.com/docs/models/gpt-4o) and review the [model card](https://openai.com/index/gpt-4o-system-card/). GPT 4o is hosted on Azure.
