Released July 20241K context≈ 384 words

A lean, purpose-built encoder designed specifically for sparse vector generation in search pipelines. It distills neural sparse encoding into a lighter footprint without abandoning the core ability to map text into sparse, interpretable token-weight representations. It trades some raw capacity for speed and efficiency, making it practical for document indexing at scale rather than general-purpose embedding tasks.

Glossary

EmbeddingA dense numerical vector that represents a word, sentence, or concept in a high-dimensional space.EncoderA model component that transforms input sequences (like protein amino acids) into meaningful numerical representations without generating new sequences.General-PurposeDesigned to handle a wide variety of different tasks rather than being specialized for one specific domain.Sparse VectorA vector representation where most values are zero, allowing efficient storage and fast similarity comparisons by only tracking non-zero positions.TokenA small unit of text (a word, subword, or punctuation mark) that a language model breaks input into for processing.Vector GenerationThe process of converting input data (like text) into numerical vectors that can be stored, compared, and searched efficiently.
