Monstral 123B v2

A Mistral-Large merge

This model is a hybrid merge of Behemoth 1.2, Tess, and Magnum V4. The intention was to do a three-way slerp merge, which is technically not possible. To simulate the effeect of a menage-a-slerp, I slerped B1.2 with tess, then separately did B1.2 with magnum. I then did a model stock merge of those two slerps using B1.2 as the base. Somehow, it worked out spectacularly well. Sometimes dumb ideas pay off.

Improvements over Monstral v1: Drummer's 1.2 tune of behemoth is a marked improvement over the original, and the addition ot tess to the mix really makes the creativity pop. I seem to have dialed out the rapey magnum influence, without stripping it of the ability to get mean and/or dirty when the situation actually calls for it. The RP output of this model shows a lot more flowery and "literary" description of scenes and activities. It's more colorful and vibrant. Repitition is dramatically reduced, as is slop (though to a lesser extent). The annoying tendency to double-describe things with "it was X, almost Y" is virtually gone. Do you like a slow-burn story that builds over time? Well good fucking news, because v2 excels at that.

The only complaint I've received is occasional user impersonation with certain cards. I've not seen this myself on any of my cards, so I have to assume it's down to the specific formatting on specific cards. I don't want to say it's a skill issue, but...

This model is uncensored and perfectly capable of generating objectionable material. I have not observed it injecting NSFW content into SFW scenarios, but no guarentees can be made. As with any LLM, no factual claims made by the model should be taken at face value. You know that boilerplate safety disclaimer that most professional models have? Assume this has it too. This model is for entertainment purposes only.

Prompt Format

Metharme seems to work flawlessly. In theory, mistral V3 or possibly even chatml should work to some extent, but meth was providing such high quality output that I couldn't even be bothered to test the others. Just do meth, kids.
