# NexaMass-V3-Struct — Technical Paper

NexaMass-V3-Struct is a compact MS/MS spectral encoder that converts tandem mass spectra into learned embeddings and Morgan-fingerprint evidence for narrowing known molecular candidate banks.

This Space presents the model’s left-aligned spectral notebook, architecture, training surfaces, inference contract, evaluation evidence, and operating limitations.
