Wiedervereinigung-7b-dpo-laser
A LaserRMT modification of mayflowergmbh/Wiedervereinigung-7b-dpo.
LaserRMT (layer-selective rank reduction) alters the base model's existing weight matrices. It is not a format conversion and not a quantisation: the weights differ from the base in substance, not merely in numeric representation.
| Base model | mayflowergmbh/Wiedervereinigung-7b-dpo |
| Licence | apache-2.0, inherited from the base |
| Architecture | MistralForCausalLM, 32 layers (unchanged from the base) |
| Modification | LaserRMT layer-selective rank reduction |
Provenance and EU AI Act Art. 53 note
This card was written on 2026-08-02. The repository had carried no model card at all since it was created on 2024-03-18 — modified weights published with no attribution to the model they were derived from. That is the gap this card closes, and it is worth stating plainly rather than quietly backfilling.
The base model above was not guessed from the repository name. It is recorded
in this repo's own config.json as _name_or_path, and the licence is the one
the base declares on the Hub as of 2026-08-02.
Provider status. Most cstr/* repositories are format conversions, where
the upstream research team remains the provider of the model under Regulation
(EU) 2024/1689 and the conversion changes only the numeric representation. This
repository is not one of those. Modifying weights places a new model on the
market, so the obligations that survive the Art. 53(2) free-and-open-source
exemption — Art. 53(1)(c) and 53(1)(d) — attach here.
Art. 53(1)(c) — copyright policy. This repository does not introduce any
training corpus of its own, so no text or data mining was carried out here and
no rights reservations under Art. 4(3) of Directive (EU) 2019/790 were engaged
by this step. The modification operates on weights already published by the base
model's authors under apache-2.0. Where the base model's own training raises
copyright questions, those attach to the base model's provider, whose
documentation is linked above. Any credible claim that this repository
redistributes material it has no right to redistribute will be acted on —
contact via the Community tab.
Art. 53(1)(d) — training content. No additional training corpus was
introduced by this repository. The model's training content is that of
mayflowergmbh/Wiedervereinigung-7b-dpo, and its documentation is the summary
that applies. This repository does not restate it, because restating training
data documentation second-hand is how inaccurate provenance claims propagate.
Known limitation. The precise LaserRMT configuration used in 2024 — which layers were reduced, and to what rank — is not recorded in this repository. It is not reconstructible from the weights alone with confidence, and it is not asserted here rather than being guessed at.
