data
array
Optional. Data for populating the Message object.
↳ citation_threshold
float
The threshold (in [0,1]) used for determining whether a fact must be cited for a claim in the answer candidate. Choosing a higher threshold will lead to fewer but very strong citations, while choosing a lower threshold may lead to more but somewhat weaker citations. If unset, the threshold will default to 0.6.
↳ enable_claim_level_score
bool
The control flag that enables claim-level grounding score in the response.
getCitationThreshold
The threshold (in [0,1]) used for determining whether a fact must be
cited for a claim in the answer candidate. Choosing a higher threshold
will lead to fewer but very strong citations, while choosing a lower
threshold may lead to more but somewhat weaker citations. If unset, the
threshold will default to 0.6.
Returns
