MediaPrompt

type MediaPrompt = string | MediaPromptPart[];

Defined in: packages/ai/src/types.ts:2363

Prompt accepted by generateImage() / generateVideo(): a plain string, or an ordered array of content parts for image-conditioned generation ("not like this (image), more like this (image)"). Part order is meaningful — adapters with native multimodal prompts (Gemini, OpenRouter) preserve the interleaving; named-field providers (fal, OpenAI, xAI) extract the media parts and flatten the text. Text is always sent verbatim: to reference inputs from the prompt, write the provider's own syntax yourself (e.g. fal's @Image1, OpenAI's "image 1"). An array may be media-only (e.g. upscalers or pure img2img endpoints that take no instruction text).
