GenerateContentResponse

Response message for [PredictionService.GenerateContent].

Fields
candidates[] object (Candidate)

Output only. Generated candidates.

modelVersion string

Output only. The model version used to generate the response.

createTime string (Timestamp format)

Output only. timestamp when the request is made to the server.

Uses RFC 3339, where generated output will always be Z-normalized and uses 0, 3, 6 or 9 fractional digits. Offsets other than "Z" are also accepted. Examples: "2014-10-02T15:01:23Z", "2014-10-02T15:01:23.045123456Z" or "2014-10-02T15:01:23+05:30".

responseId string

Output only. responseId is used to identify each response. It is the encoding of the eventId.

promptFeedback object (PromptFeedback)

Output only. Content filter results for a prompt sent in the request. Note: Sent only in the first stream chunk. Only happens when no candidates were generated due to content violations.

usageMetadata object (UsageMetadata)

FinishReason

The reason why the model stopped generating tokens. If empty, the model has not stopped generating the tokens.

Enums
FINISH_REASON_UNSPECIFIED The finish reason is unspecified.
STOP token generation reached a natural stopping point or a configured stop sequence.
MAX_TOKENS token generation reached the configured maximum output tokens.
SAFETY token generation stopped because the content potentially contains safety violations. NOTE: When streaming, content is empty if content filters blocks the output.
RECITATION The token generation stopped because of potential recitation.
OTHER All other reasons that stopped the token generation.
BLOCKLIST token generation stopped because the content contains forbidden terms.
PROHIBITED_CONTENT token generation stopped for potentially containing prohibited content.
SPII token generation stopped because the content potentially contains Sensitive Personally Identifiable Information (SPII).
MALFORMED_FUNCTION_CALL The function call generated by the model is invalid.
