Overview

More than just a model picker, {% data variables.copilot.copilot_auto_model_selection_short %} is an intelligent system delivering high quality results, better reliability, and one less decision to make as the model landscape rapidly evolves.

Auto with task optimization

[!NOTE] {% data variables.copilot.copilot_auto_model_selection_short_cap_a %} with task optimization is generally available in {% data variables.copilot.copilot_chat_short %} in {% data variables.product.prodname_vscode_shortname %}.

{% data variables.copilot.copilot_auto_model_selection_short_cap_a %} with task optimization combines two systems to provide high quality results and better reliability. One system tracks real-time system health and availability, while the other evaluates task complexity. Putting these together, {% data variables.copilot.copilot_auto_model_selection_short %} routes the task to the optimal model.

Routing occurs along natural cache boundaries to avoid additional cache related costs. Switching models mid-session has shown increased cost without ample improvements in quality. This helps you get more value from {% data variables.product.prodname_copilot_short %} since it matches each task to the model that can solve it most efficiently. That means reserving higher-cost reasoning models for problems that truly need it, while routing straightforward tasks to faster, lower-cost models that still deliver great results.

Benefits of using {% data variables.copilot.copilot_auto_model_selection_short %} include:

• Matching each task to the model that can solve it most efficiently.
• Model choice based on real-time system health and availability.
• Language invariance: Routing decisions depend on what you are trying to do, not what language you're asking in.
• Improved cost efficiency due to intelligent task routing.

Auto optimized for model reliability and availability

Experience less rate limiting by letting {% data variables.copilot.copilot_auto_model_selection_short %} choose the best available model on your behalf.

{% data variables.copilot.copilot_auto_model_selection_short_cap_a %}, optimized for model reliability and availability, intelligently chooses models based on real-time system health and model performance. You benefit from:

• Reduced rate limiting
• Lower latency and errors

Policies and availability

When you select Auto, {% data variables.copilot.copilot_auto_model_selection_short %} chooses from supported models, subject to your policies and subscription type. Available models may change over time. See AUTOTITLE.

{% data variables.copilot.copilot_auto_model_selection_short_cap_a %} won't include these models:

• Models not available in your plan.
• Models excluded by administrator policies. See AUTOTITLE.
• Models excluded by policies restricting {% data variables.product.prodname_copilot_short %} to data-resident or FedRAMP-compliant models.
• Models with premium request multipliers greater than one.

Multiplier discounts

{% data variables.copilot.copilot_auto_model_selection_short_cap_a %} in {% data variables.product.prodname_copilot_short %}

{% data variables.copilot.copilot_auto_model_selection_short_cap_a %}, optimized for model reliability and availability, is available in these {% data variables.product.prodname_copilot_short %} products:

• {% data variables.copilot.copilot_chat_short %}
• {% data variables.copilot.copilot_cli_short %}
• {% data variables.copilot.copilot_cloud_agent %}

Tip

You can see which model was used for each {% data variables.product.prodname_copilot_short %} response.

• In {% data variables.copilot.copilot_chat_short %}, hover over the response.
• In {% data variables.copilot.copilot_cli_short %}, the model used for each response displays in the terminal.
• In {% data variables.copilot.copilot_cloud_agent %}, the model used for each response displays at the end of the response.
