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` | [Optional\[components.Embeddings\]](../components/embeddings.mdx) | :heavy\_minus\_sign: | N/A | | `image_generation` | [Optional\[components.ImageGeneration\]](../components/imagegeneration.mdx) | :heavy\_minus\_sign: | N/A | | `rerank` | [Optional\[components.Rerank\]](../components/rerank.mdx) | :heavy\_minus\_sign: | N/A | | `stt` | [Optional\[components.STT\]](../components/stt.mdx) | :heavy\_minus\_sign: | N/A | | `text_generation` | [Optional\[components.TextGeneration\]](../components/textgeneration.mdx) | :heavy\_minus\_sign: | N/A | | `tts` | [Optional\[components.TTS\]](../components/tts.mdx) | :heavy\_minus\_sign: | N/A | | `unknown` | [Optional\[components.Unknown\]](../components/unknown.mdx) | :heavy\_minus\_sign: | N/A | | `video_generation` | [Optional\[components.VideoGeneration\]](../components/videogeneration.mdx) | :heavy\_minus\_sign: | N/A |
