Multimodal Embedding Serving#

GitHub project Readme

The Multimodal Embedding Serving microservice provides a scalable and efficient solution for generating multimodal embeddings from text, images, and videos. Built on state-of-the-art vision-language models, it enables applications to perform cross-modal search, retrieval, and similarity tasks through a simple, production-ready service.

Architecture#

The microservice is designed as a RESTful API service that:

  • Accepts text, image, and video inputs through OpenAI-compatible endpoints

  • Loads and manages multiple vision-language models dynamically

  • Provides hardware-accelerated inference using OpenVINO for Intel hardware

  • Returns high-dimensional embeddings in a shared semantic space

  • Supports both synchronous and batch processing workflows

Model Support#

The service supports multiple model families:

  • CLIP: General-purpose vision-language understanding

  • CN-CLIP: Chinese-optimized models for multilingual applications

  • MobileCLIP: Lightweight models for mobile and edge deployment

  • SigLIP: Models with sigmoid loss function

  • BLIP-2: Advanced multimodal models with Q-Former architecture

For complete model specifications, see Supported Models.

Key Capabilities#

  • OpenAI-Compatible API: Standard embeddings API format for seamless integration

  • Multi-Modal Processing: Handle text, images (URL/base64), and videos (URL/base64/file)

  • Hardware Optimization: CPU and GPU support with OpenVINO acceleration

  • Video Processing: Advanced frame extraction with configurable sampling strategies

  • Production Features: Health checks, monitoring, logging, and scalability

Deployment Architecture#

The microservice can be deployed in multiple configurations:

  • Docker Containers: Single-node deployment using Docker Compose

  • Kubernetes: Multi-node scalable deployment

  • Python SDK: Direct integration into Python applications

The same container image supports both CPU and GPU deployments through runtime configuration.
