POST /v1/chat/completions

Speed-optimised multimodal embedding model. Same input/output shape as Tongyi-Embedding-Vision-Plus but with cheaper image/video pricing — ideal for high-volume image and video indexing workflows. For text-only embeddings, use Text-Embedding-v4 instead.

Parameters

Parameter	Type	Required	Default	Description
`input`	array	yes	—	Array of content parts. Either OpenAI shape `[{type:"image",url:"..."},{type:"text",text:"..."}]` or DashScope shape `{contents:[{image:"..."},{text:"..."}]}`. Up to 8 images @3 MB each, video up to 10 MB, text up to 1024 tokens.
`user`	string	no	—	—

Notes

Embedding dimension: fixed at 768.\n\nPer-input limits:\n\n- Text: up to 1,024 tokens\n- Images: up to 8 per request, max 3 MB each (JPG, PNG, BMP)\n- Video: up to 10 MB per file (MP4, MPEG, MOV, MPG, WEBM, AVI, FLV, MKV)\n\nPricing: image/video tokens bill at $0.03/1M (3x cheaper than the Plus variant). Text tokens bill at$ 0.09/1M — same as Plus, so prefer Text-Embedding-v4 for text-only workloads.\n\nLanguages: Chinese and English.
