Type Alias: GenerationActivity#

type GenerationActivity = "chat" | "image" | "video" | "audio" | "tts" | "transcription";

Defined in: packages/ai/src/activities/middleware/types.ts:34

The activity an observability event describes.

Mirrors the public surface a caller reaches for: 'chat' for chat(), and the media kinds for the generate* activities. 'tts' matches the speech adapter's kind (the public discriminator avoids inventing a parallel 'speech'/'text' vocabulary). otelMiddleware maps each to its gen_ai.operation.name.
