Copilot

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.

{% vscode %} You can switch AI models in the latest releases of {% data variables.product.prodname_vscode_shortname %} with the latest version of the {% data variables.product.prodname_copilot %} extension. {% endvscode %}

{% visualstudio %} You can switch AI models in {% data variables.product.prodname_vs %} 17.14 Preview 2 and later. {% endvisualstudio %}

{% jetbrains %} You can switch AI models in the latest releases of JetBrains IDEs with the latest version of the {% data variables.product.prodname_copilot %} extension. {% endjetbrains %}

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.

Changing the AI model for code completion

The following instructions are for {% data variables.product.prodname_vscode_shortname %}. If you are using {% data variables.product.prodname_vs %}, or a JetBrains IDE, click the appropriate tab at the start of this article.

  1. Open the command palette by pressing Ctrl+Shift+P (Windows/Linux) / Command+Shift+P (Mac).
  2. Type change completions model and select the "{% data variables.product.prodname_copilot %}: Change Completions Model" command.
  3. In the dropdown menu, select the model you want to use.

Alternatively, if Command Center is enabled, you can click {% octicon "chevron-down" aria-label="The downward-pointing arrowhead" %} beside the {% octicon "copilot" aria-hidden="true" %} icon at the top of the {% data variables.product.prodname_vscode_shortname %} window, then click Configure Code Completions in the dropdown menu. Then choose Change Completions Model in the dropdown menu and select the model you want to use.

Checking which model is being used

  1. Open the Settings editor by pressing Ctrl+, (Linux/Windows) / Command+, (Mac).

  2. Type copilot completion and look for the "{% data variables.product.github %} > {% data variables.product.prodname_copilot_short %}: Selected Completion Model" section.

    The field in this section displays the currently selected model. If the field is empty, the default model is being used.
