By default, {% data variables.product.prodname_copilot_chat_short %} uses OpenAI's GPT-4o large language model. This is a highly proficient model that performs well for text generation tasks, such as summarization and knowledge-based chat. The model is also capable of reasoning, solving complex math problems and coding.
|
|
|
|
However, you are not limited to using this model. You can choose from a selection of other models, each with its own particular strengths. You may have a favorite model that you like to use, or you might prefer to use a particular model for inquiring about a specific subject.
|
|
|
|
{% data variables.product.prodname_copilot_short %} allows you to change the model during a chat and have the alternative model used to generate responses to your prompts.
|
|
|
|
Changing the model that's used by {% data variables.product.prodname_copilot_chat_short %} does not affect the model that's used for {% data variables.product.prodname_copilot_short %} code completion. See [AUTOTITLE](/copilot/using-github-copilot/ai-models/changing-the-ai-model-for-copilot-code-completion).

This is the full-page version of {% data variables.product.prodname_copilot_chat_short %} that's displayed at [https://github.com/copilot](https://github.com/copilot). The {% data variables.product.prodname_copilot_chat_short %} panel always uses the default model.
