Some questions about the open-ended evaluation

[Eldo-rado]

Hi! @zhjohnchan

Thank you for your contribution, this is excellent work!
Could you please provide the code related to this section in the paper:

Since open-ended, free-text outputs from FMs are challenging to evaluate, we instead compute log-likelihood scores associated with each option; the option with the highest score is then selected as the response.

Thank you in advance!
