Experimental models give you the opportunity to test cutting-edge capabilities before they reach general availability. You can evaluate performance against your use cases and existing models to prepare for deployment. As experimental models, we recommend using them in non-production scenarios while we complete our evaluation gates. This approach allows you to stay ahead of the curve, experimenting with the latest AI models while we ensure they meet quality standards.

You can learn more about using the latest models in Copilot Studio here.
