## What's New

June 7, 2024

#### Similarity Search

Find items similar to your selected reference embeddings using cosine similarity. Perfect for working with image or text embeddings, this powerful tool facilitates precise comparisons, allowing you to efficiently discover similar items. Adjust your own thresholds to fine-tune search sensitivity, or explore the central tendencies of multiple embeddings to pinpoint items that best match the core attributes of your data.
