Helsinki-NLP / opus-mt-nl-en

No training-data disclosure found on the model card.

At every check so far the published predicate returned false: the card does not name its training data. Crovia fetches the Hugging Face model card of Helsinki-NLP/opus-mt-nl-en in hourly TACET epochs, runs the published predicate crovia.pred.hf-card-training-data 1.0.0 over the exact bytes, signs the result and commits it to a sparse Merkle map that is anchored in Bitcoin. Numbers below are observation facts, not a judgement of the model.

Epoch sheets

Every observation is in the public log

Each hourly epoch sheet lists the snapshot of Helsinki-NLP/opus-mt-nl-en with its signature and its leaf in the sparse Merkle map. Featured models get a wrapped level-2 proof automatically; for any other model you can request a certificate and receive the same object.

What this record means

Observation facts only

  • Surface: the raw model card on Hugging Face (last fetched URL). A disclosure published elsewhere is not seen here.
  • Predicate: crovia.pred.hf-card-training-data 1.0.0 — a pure function of the bytes, published with its hash. It accepts thin disclosures; it never rates quality.
  • Time: each epoch is opened by a drand round and closed by a Bitcoin block, so the window is not chosen by Crovia.
  • Not a grade. Crovia does not rank, score or accuse. It records what was observable, signs it, and lets anyone check.
