A list of indices that refer to specific GroundingChunk objects within the GroundingMetadata.groundingChunks array. These referenced chunks are the sources that support the claim made in the associated segment of the response. For example, an array [1, 3, 4] means that groundingChunks[1], groundingChunks[3], and groundingChunks[4] are the retrieved content supporting this part of the response.
Specifies the segment of the model's response content that this grounding support pertains to.
GroundingSupport.groundingChunkIndices
A list of indices that refer to specific GroundingChunk objects within the GroundingMetadata.groundingChunks array. These referenced chunks are the sources that support the claim made in the associated segment of the response. For example, an array [1, 3, 4] means that groundingChunks[1], groundingChunks[3], and groundingChunks[4] are the retrieved content supporting this part of the response.
Signature:
groundingChunkIndices?:number[];
GroundingSupport.segment
Specifies the segment of the model's response content that this grounding support pertains to.
