### 1. On-Premise, Optimized: FastEmbed by Qdrant
|

|
||||
[FastEmbed](https://qdrant.tech/documentation/fastembed/) is Qdrant's optimized embedding solution designed for on-premise, high-speed generation with minimal dependencies. It delivers low-latency, CPU-friendly embedding generation using quantized model weights and ONNX Runtime, making it up to 50% faster than traditional PyTorch-based models while maintaining competitive accuracy.

The default model for standalone use, [`BAAI/bge-small-en-v1.5`](https://huggingface.co/BAAI/bge-small-en-v1.5), is lightweight at ~67MB compared to 300MB+ for many Hugging Face models. While the `qdrant-client` integration allows you to specify any compatible model, using the default is a great way to get started quickly.

When searching for dog images, for example, the vector finds visually similar images while payload filters narrow results to images taken within the last year, tagged with "vacation," or meeting specific rating criteria.
