About Copilot 自动模型选择

Overview

More than just a model picker, 自动模型选择 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

注意

自动模型选择 with task optimization is generally available in 副驾驶聊天 in VS Code.

自动模型选择 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, 自动模型选择 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 Copilot 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 自动模型选择 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 自动模型选择 choose the best available model on your behalf.

自动模型选择, 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, 自动模型选择 chooses from supported models, subject to your policies and subscription type. Available models may change over time. See GitHub Copilot中支持的 AI 模型.

自动模型选择 won't include these models:

Models not available in your plan.
Models excluded by administrator policies. See 在 GitHub Copilot 中配置对 AI 模型的访问.
Models excluded by policies restricting Copilot to data-resident or FedRAMP-compliant models.
Models with premium request multipliers greater than one.
