Get multimodal embeddings

The multimodal embeddings model generates 1408-dimension vectors* based on the input you provide, which can include a combination of image, text, and video data. The embedding vectors can then be used for subsequent tasks like image classification or video content moderation.

The image embedding vector and text embedding vector are in the same semantic space with the same dimensionality. Consequently, these vectors can be used interchangeably for use cases like searching image by text, or searching video by image.

For text-only embedding use cases, we recommend using the Vertex AI text-embeddings API instead. For example, the text-embeddings API might be better for text-based semantic search, clustering, long-form document analysis, and other text retrieval or question-answering use cases. For more information, see Get text embeddings.

Supported models

You can get multimodal embeddings by using the following model:

• multimodalembedding

Best practices

Consider the following input aspects when using the multimodal embeddings model:

• Text in images - The model can distinguish text in images, similar to optical character recognition (OCR). If you need to distinguish between a description of the image content and the text within an image, consider using prompt engineering to specify your target content. For example: instead of just "cat", specify "picture of a cat" or "the text 'cat'", depending on your use case.

  the text 'cat'
  picture of a cat

• Embedding similarities - The dot product of embeddings isn't a calibrated probability. The dot product is a similarity metric and might have different score distributions for different use cases. Consequently, avoid using a fixed value threshold to measure quality. Instead, use ranking approaches for retrieval, or use sigmoid for classification.

A location is a region you can specify in a request to control where data is stored at rest. For a list of available regions, see Generative AI on Vertex AI locations.

Error messages

Quota exceeded error

google.api_core.exceptions.ResourceExhausted: 429 Quota exceeded for
aiplatform.googleapis.com/online_prediction_requests_per_base_model with base
model: multimodalembedding. Please submit a quota increase request.

If this is the first time you receive this error, use the Google Cloud console to request a quota increase for your project. Use the following filters before requesting your increase:

• Service ID: aiplatform.googleapis.com
• metric: aiplatform.googleapis.com/online_prediction_requests_per_base_model
• base_model:multimodalembedding

Go to Quotas

If you have already sent a quota increase request, wait before sending another request. If you need to further increase the quota, repeat the quota increase request with your justification for a sustained quota request.

Specify lower-dimension embeddings

By default an embedding request returns a 1408 float vector for a data type. You can also specify lower-dimension embeddings (128, 256, or 512 float vectors) for text and image data. This option lets you optimize for latency and storage or quality based on how you plan to use the embeddings. Lower-dimension embeddings provide decreased storage needs and lower latency for subsequent embedding tasks (like search or recommendation), while higher-dimension embeddings offer greater accuracy for the same tasks.

Send an embedding request (video, image, or text)

When sending an embedding request you can specify an input video alone, or you can specify a combination of video, image, and text data.

Video embedding modes

There are three modes you can use with video embeddings: Essential, Standard, or Plus. The mode corresponds to the density of the embeddings generated, which can be specified by the interval_sec config in the request. For each video interval with interval_sec length, an embedding is generated. The minimal video interval length is 4 seconds. Interval lengths greater than 120 seconds might negatively affect the quality of the generated embeddings.

Pricing for video embedding depends on the mode you use. For more information, see pricing.

The following table summarizes the three modes you can use for video embeddings:

Video embeddings best practices

Consider the following when you send video embedding requests:

• To generate a single embedding for the first two minutes of an input video of any length, use the following videoSegmentConfig setting:

  request.json:

  // other request body content
  "videoSegmentConfig": {
    "intervalSec": 120
  }
  // other request body content
  

• To generate embedding for a video with a length greater than two minutes, you can send multiple requests that specify the start and end times in the videoSegmentConfig:

  request1.json:

  // other request body content
  "videoSegmentConfig": {
    "startOffsetSec": 0,
    "endOffsetSec": 120
  }
  // other request body content
  

  request2.json:

  // other request body content
  "videoSegmentConfig": {
    "startOffsetSec": 120,
    "endOffsetSec": 240
  }
  // other request body content
  

Get video embeddings

Use the following sample to get embeddings for video content alone.
