Static Embedding Models Released, Up to 400x Faster on CPU

·2025.01.15 09:00

Key point

A static embedding model and training methodology have been released that deliver up to 400 times faster speed than existing models in CPU environments.

Details

Hugging Face has released a training method for Static Embedding models that are 100 to 400 times faster than existing SOTA embedding models in CPU environments.

This methodology dramatically increases inference speed while maintaining performance at about 85% of the level of existing models, making it optimized for low-power environments such as on-device, browser execution, and edge computing.

Key releases:

  • New models: Two models — one for English retrieval (static-retrieval-mrl-en-v1) and one for multilingual similarity (static-similarity-mrl-multilingual-v1)
  • Training resources: Detailed training strategy, datasets (30 for training, 13 for evaluation), training scripts, and W&B reports
  • Ease of use: Can be immediately applied through the same workflow as the existing Sentence Transformers library
