👁 Impish_Bloodmoon_12B

---

---

This repo was created on September 1st; it's the end of December now. But on the bright side, you guys get not one, but two models! 🙂

(For the "boring technical stuff", you can go to the training details section. In short, I needed to make an adapter, so while at it, I decided to test how far Nemo 12B can be pushed while doing only a deep LoRA, and it turns out quite a lot was possible!)

This is a double release, since I worked on several different things simultaneously. So even though this took more time than I'd like, 2 models instead of one, totally worth it the 4-month wait, eh? and these two piles of tensors couldn't be more different from each other— they are complete opposites. They do share a similar core though, but branched in very different directions.

The "sane and pure one" is Angelic_Eclipse_12B, superb at 'slow-burn'. Production-ready, with robust safety (arguably even safer than stock Mistral Nemo), while retaining full roleplay and creative writing capabilities. In other words, it will give you roleplay freedom, but would steer towards SFW, and would not tell you how to make... some stuff.

Unlike this model.

This is one of the most 'Impish' models of the whole Impish line. Ironically, it might even be more 'Impish' than Impish_Nemo_12B. Imagine that.

Impish_Bloodmoon_12B is an especially wicked one, as I turned the heat to 11 for its innate personality. It has some very interesting capabilities besides just story writing, adventure and roleplay. For example, it could be used to 1-shot roleplay datasets in JSON form directly, and lots of other cool stuff (robust GEC, powerful synonym engine, and many more features that are too many to list, in short, it's a very powerful assistant, specifically for creative tasks). The one-shot dataset creation would prove especially useful for beginner model tuners. This specific capability, along with some others, is only available for this model specifically, and not for its "saner" sister-model.

Impish_Bloodmoon_12B was named this way, in part because I thought: "sheesh, this will probably take a long time to make, probably like... a month or so!", so anyway, 4 months later... (Well, at least the blood part was accurate— 'blood, sweat and tears' and all of that...)

As per usual- improvements to logic, dataset quality, deslopping, more Morrowind, more Fallout, and so on and so forth. In short, it's an absolutely monstrous dataset in terms of tokens trained, it's a generalist with fire flowing throughout its neurons, added multi-lingual support (Russian, Hebrew, Japanese), tons of features, and an innate spicy personality.

A complete overhaul and refinement was undertaken to vastly improve the dataset in:

• Multi-character interactions
• Theory of mind
• Multi-agent game theory
• Understanding strategic deception
• Item \ stat tracking over long context

Oh, and I let a friend meticulously check these capabilities by hand. This example is fully available here. So don't just take my word for it. Do like the Soviets- trust, but verify ☭ (The example was made using the included adventure card, with these Silly Tavern settings)

No editing was done to any of the replies. For the entire run, only up to 5 regens were allowed, start to finish. (in other words, what you see is what you'll get, let's be transparent, dammit 😄)

Have fun! 😈

So why 2 models?

Training details

TL;DR

• Frontier-adjacent like capabilities, now locally available in 12B! (Stats, items, traits triggering, and so much more).
• Very strong theory of mind!
• Well over 1B tokens trained!
• Fallout & Morrowind fandom refined!
• Heat turned to 11!
• 3 additional languages added: Japanese, Hebrew, Russian.
• 1-shot JSON roleplay datasets! Escape velocity reached! (even for those who can't run DSV3 \ Kimi).
• Less positivity bias , all lessons from the successful Negative_LLAMA_70B style of data learned & integrated, with serious upgrades added — and it shows! (Note: if this bites you a bit too hard, try Angelic_Eclipse_12B. 👼)
• Reduced slop for both roleplay and creative tasks.
• Trained on an extended 4chan dataset to add humanity. Further improved.
• Dynamic length response based on the level of details needed. For roleplay: 1–5 paragraphs, usually 2–4. For adventure: 1–10 paragraphs, usually 2–5.
• VERY creative, high swipe diversity

Regarding the format:

It is HIGHLY RECOMMENDED to use the Roleplay \ Adventure format the model was trained on, see the examples below for syntax. It allows for a very fast and easy writing of character cards with minimal amount of tokens. It's a modification of an old-skool CAI style format I call SICAtxt (Simple, Inexpensive Character Attributes plain-text):
