Scores whether a sequence looks like a natural protein rather than random or poorly formed sequence.

Realness

Realness estimates whether a protein sequence looks biologically plausible.

What It Does

The oracle helps flag sequences that may be random, corrupted, overly artificial, or outside the range of natural protein-like patterns.

Why It Matters

Generated sequences can look valid at the character level while still being biologically implausible. Realness gives teams a fast quality-control signal before investing in deeper analysis or synthesis.

Intended Use

Use Realness to triage generated proteins, uploaded sequences, and variant libraries. It is most helpful alongside structure prediction, solubility, annotation, and interaction analysis.

Limitations

Realness does not prove that a sequence folds, expresses, binds, or functions. Some useful designed proteins may look unusual, and some natural-like proteins may still fail experimentally.
