Additive to the legacy singular latency and throughput fields; image and video generation report end-to-end latency. Only visible when authenticated with an API key or cookie. ## Fields | Field | Type | Required | Description | | ----------------- | --------------------------------------------------------------------------- | -------------------- | ----------- | | `Embeddings` | [\*components.Embeddings](../../models/components/embeddings.mdx) | :heavy\_minus\_sign: | N/A | | `ImageGeneration` | [\*components.ImageGeneration](../../models/components/imagegeneration.mdx) | :heavy\_minus\_sign: | N/A | | `Rerank` | [\*components.Rerank](../../models/components/rerank.mdx) | :heavy\_minus\_sign: | N/A | | `STT` | [\*components.STT](../../models/components/stt.mdx) | :heavy\_minus\_sign: | N/A | | `TextGeneration` | [\*components.TextGeneration](../../models/components/textgeneration.mdx) | :heavy\_minus\_sign: | N/A | | `TTS` | [\*components.TTS](../../models/components/tts.mdx) | :heavy\_minus\_sign: | N/A | | `Unknown` | [\*components.Unknown](../../models/components/unknown.mdx) | :heavy\_minus\_sign: | N/A | | `VideoGeneration` | [\*components.VideoGeneration](../../models/components/videogeneration.mdx) | :heavy\_minus\_sign: | N/A |
