mistralai / Mixtral-8x7B-v0.1

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 mistralai/Mixtral-8x7B-v0.1 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.

Level-2 silence proof

A signed proof exists for this model

The proof wraps every negative observation of mistralai/Mixtral-8x7B-v0.1 in a Crovia Seal: sparse-Merkle non-inclusion for each epoch, the drand round that opened it and the OpenTimestamps receipt that closed it. Your browser checks all of it, Bitcoin anchor included.

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.
