Hey folks - curious how BAML type checks work. Suppose I have a prompt that expects a response of ENUM type, but I notice the LLM (Gemini 3 flash) keeps giving an output with an ENUM type, but followed by a large chunk of explanation of its reasoning. Does BAML reject that or somehow parse the ENUM response from that? If it does parsing, what's the logic?

Great question! We do try to parse the enum value out from any string the LLM gives. IIRC we regex search for your enum variants.

got it. What if the LLM answer included more than one ENUM value? For example, if it answered: "Answer: RED The picture looks like a red horse, not a BLUE, YELLOW, or GREEN one, so the answer is RED." All four ENUM values are mentioned

Then we reject it!

Sounds great
