By default, Copilot Chat uses GPT-4.1 to provide fast, capable responses for a wide range of tasks, such as summarization, knowledge-based questions, reasoning, math, 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.
Примечание.
Different models have different premium request multipliers, which can affect how much of your monthly usage allowance is consumed. For details, see About premium requests.
Copilot 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 Copilot Chat does not affect the model that's used for Copilot code completion. See Changing the AI model for Copilot code completion.
