# OPT-2.7B-Nerybus-Mix

This is an experimental model containing a ***parameter-wise 50/50 blend (weighted average)*** of the weights of *NerysV2-2.7B* and *ErebusV1-2.7B*
Preliminary testing produces pretty coherent outputs, it appears to retain the NSFWness of Erebus but with a Nerys-esque twist in terms of prose.

# License
The two models used for this blend, *NerysV2-2.7B* and *ErebusV1-2.7B* are made by **Mr. Seeker**.

# Evaluation Results
As the original datasets used for the source models are not publically available, I use my own datasets for this evaluation, which may not provide accurate comparison.

Eval parameters: 25000 characters extracted from the middle of the corpus, tested in blocks of 1024 tokens each, same dataset used for each test batch.
