HF Search Booster is a free Chrome extension designed to improve the search functionality of Hugging Face's model repository. This tool offers smart query matching, ensuring that only relevant model cards appear in your search results, thereby enhancing user efficiency. It also introduces variant file size details, allowing users to view the real file sizes for various model variants, such as GGUF and SafeTensors, with a convenient min-max range badge on each card.

In addition, HF Search Booster features an intuitive hover detail option, which displays comprehensive model file information upon hovering over a card. Users can easily filter their search results based on size with a dual-range slider and precise number inputs, making it easier to find models that fit specific GPU or disk constraints. The extension also includes an auto-scan feature that populates sizes automatically as users scroll, a persistent cache for quick refreshes, and customizable settings for toggling features without uninstalling the extension.
