ARC-Encoder: portable continuous context compression

Contribution grade

Language-model context compression · Human-designed research method or resource

Reference score55,000Provisional editorial estimate of this exact contribution; its grade is assessed separately.

What changed

Trained an encoder to replace text embeddings with fewer continuous pooled representations and small decoder-specific mappings, supporting multiple unchanged decoders and compressed context extension.

Scientific scope

Trained an encoder to replace text embeddings with fewer continuous pooled representations and small decoder-specific mappings, supporting multiple unchanged decoders and compressed context extension. Lossy task-oriented compression requires encoder training and preprocessing; it is not lossless text storage or free context extension. Inherits soft compression and pretrained decoders. Portability is demonstrated for studied decoder families, not arbitrary models.
