A Suno v6 file can carry provenance information and can be submitted to an AI classifier. These are different checks. Suno documents Content Credentials, but a detector naming Suno does not by itself establish a decoded watermark or a validated v6-specific fingerprint.

What Suno documents about v6

Suno introduced the v6 family on September 9, 2026, distinguishing v6, v6-wild and v6-mini. Preserve the exact model name from the generation record: a result on one family member should not silently become a result for all three.

The Safety Center separately describes attaching Content Credentials to generated songs and provides a verification route. This documents a provenance mechanism; it does not publish the internal features of a commercial AI classifier.

What a detector’s Suno label means

SH Labs lists Suno among its supported generators. At review, its public list named 4.5, 4.5+, 5+ and legacy versions rather than a separate v6 benchmark. A broad label such as 5+ must not be rewritten as a measured v6 success rate.

Keep the exact returned category in your report. If a v6 source receives an older Suno label, that is an observed classifier attribution, not evidence that the generation record is wrong. Read how to interpret scores and labels.

What research can explain, and what it cannot

The 2025 Fourier artifacts paper links certain generator architectures to systematic spectral patterns and evaluates detection on generated music. It predates the v6 release above. It is background for understanding fingerprints, not a published v6 evaluation or a description of SH Labs’ implementation.

Likewise, a Human Made classification after processing does not verify that Content Credentials were removed. Use the appropriate provenance verifier when investigating that separate question.

How to document a v6 result

  1. Record the generation date, exact model variant and original export format.
  2. Retain the original file and its detector report.
  3. Process a separate copy and retain the output report with the output.
  4. Record the analysis date and returned category without renaming it.
  5. Evaluate audio quality separately from the classification.

Demorphus has tested Suno v6 internally, but this page does not publish a version-specific pass rate: a matched v6 test set with files and reports is not supplied here. The existing test summary is a different, aggregate collection.

Start with the checker, then use Cleaner to obtain a processed export and its report.
