1. Is this request related to a challenge you're experiencing? Tell me about your story.

In the context of Dify models, there is currently no support for invoking built-in functions specific to model vendors, such as online query functionalities. Each model vendor provides its own distinct methods for performing online queries and other similar operations. To enhance functionality and flexibility, it would be beneficial to add support for calling these vendor-specific built-in functions.

This addition would allow users to leverage the full capabilities provided by each model vendor within the Dify framework, thus improving the overall utility and adaptability of the models used.

Thank you for considering this feature request.
