# ## Grammar-Constrained Generation
#
# OpenAI models also support constrained generation in the [Responses API](https://platform.openai.com/docs/guides/function-calling#context-free-grammars). This forces the LLM to produce output which conforms to the given grammar, which is useful when specific syntax is required in the output.
#
# In this example, we will define a simple Lark grammar which prevents the model from giving a correct answer to a simple question, and compare that to the unconstrained model.
#
# Note that as of October 2025, this is only supported by OpenAI (not Azure) on "gpt-5"
