Overview

By default, {% data variables.product.prodname_copilot_short %} code completion uses the GPT-4o {% data variables.product.prodname_copilot_short %}, a fine-tuned GPT-4o mini based large language model (LLM). This model has been trained on a wide range of high quality public {% data variables.product.github %} repositories, providing coverage of over 30 programming languages. Its knowledge base is more current than the default model and you may find that it generates completion suggestions more quickly.

Note

• Multiple model support for {% data variables.product.prodname_copilot_short %} code completion is in {% data variables.release-phases.public_preview %} and is subject to change.
• You can switch AI models in {% data variables.product.prodname_vs %} 17.14 Preview 2 and later, and in the latest JetBrains IDEs, with the latest version of the {% data variables.product.prodname_copilot %} extension.

Effects of switching the AI model

Changing the model that's used for {% data variables.product.prodname_copilot_short %} code completion does not affect the model that's used by {% data variables.product.prodname_copilot_chat_short %}. See AUTOTITLE.

There are no changes to the data collection and usage policy if you change the AI model.

If you are on a {% data variables.product.prodname_copilot_free_short %} subscription, all completions count against your completions quota regardless of the model used. See AUTOTITLE.

The setting to enable or disable suggestions that match public code are applied irrespective of which model you choose. See AUTOTITLE.

Enabling the model switcher

{% ifversion fpt %}

If you have a {% data variables.product.prodname_copilot_free_short %} or {% data variables.product.prodname_copilot_pro_short %} subscription, the model switcher for {% data variables.product.prodname_copilot_short %} code completion is automatically enabled.
