Overview

More than just a model picker, sélection automatique de modèle 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

Remarque

Sélection automatique de modèle with task optimization is generally available in Discussion avec Copilot in VS Code.

Sélection automatique de modèle 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, sélection automatique de modèle 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 sélection automatique de modèle 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 sélection automatique de modèle choose the best available model on your behalf.

Sélection automatique de modèle, 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, sélection automatique de modèle chooses from supported models, subject to your policies and subscription type. Available models may change over time. See Modèles IA pris en charge dans GitHub Copilot.
