nisqa-v2-weight (Vokra GGUF)

Converted to the Vokra GGUF format for Vokra, a zero-dependency speech-AI inference runtime.

This is a conversion, not a new model. The weights are the upstream ones; Vokra re-packages them so its runtime can memory-map them directly. Credit for the model belongs upstream — see Source below.

Every row above is read out of this file's own vokra.* metadata, so the card cannot claim something the artifact does not carry.

Licence

The weights are distributed under cc-by-nc-sa-4.0, unchanged from upstream. Conversion does not alter the licence, and your obligations run to the upstream author.

⚠️ Share-alike / copyleft — this licence travels with the file

This weight is cc-by-nc-sa-4.0, and that licence is not discharged by attribution alone. It attaches to derivatives.

• This GGUF is a conversion of an upstream weight, so it is itself cc-by-nc-sa-4.0 — not Apache-2.0, and not covered by Vokra's own licence.
• Anything you derive from it (a fine-tune, a re-quantisation, a further format conversion) carries the same licence.
• Vokra's runtime is Apache-2.0. Loading this weight does not change that, because these licences restrict the terms of redistribution, not use. Shipping the weight onward is what carries the obligation.

⛔ Non-commercial — you may not use this weight commercially

The upstream weight is cc-by-nc-sa-4.0. It is republished here so the model can be evaluated and used for research, and the licence is unchanged by conversion.

• Do not use this in a commercial product or service. That restriction is upstream's, not Vokra's, and Vokra cannot waive it.
• Vokra's engine is Apache-2.0 and imposes no such limit — the limit is on this weight. Other models in this organisation are permissively licensed; check each one's card.
• Vokra's runtime refuses to load a non-commercial weight unless an explicit research flag is set, so this restriction is enforced at load time rather than left to the reader.
