Question about ENUM Support

As I saw recently, Generate structured output with the Gemini API  |  Google AI for Developers, you can now use ENUMs to define your response. I wanted to understand the use case here. Given that the ENUM example shows you are getting ONE result (ie, one of the ENUM values), if I needed a more complex result, I’d use JSON Schema, and since you can define ENUMs there, I can get similar results. Right?

Hey Raymond, that’s right! The choice between using ENUMs and JSON schema really depends on how complex your use case is. If you’ve got a single field that you need to limit to a few set values (like for classification, sentiment analysis, or showing the state of something), ENUMs are definitely the most efficient way to go. But, if you need to define a more structured output with lots of fields, nested objects, and that kind of thing, then JSON schema is what you’ll want to use.
