Click here for TL;DR


It's the 20th of June, 2025 —The world is getting more and more chaotic, but let's look at the bright side: Mistral released a new model at a very good size of 24B , no more "sign here" or "accept this weird EULA" there, a proper Apache 2.0 License , nice! 👍🏻

This model is based on mistralai/Magistral-Small-2506 so naturally I named it Impish_Magic . Truly excellent size, I tested it on my laptop ( 16GB gpu ) and it works quite fast ( 4090m ).

This model went "full" fine-tune over 100m unique tokens . Why do I say "full"?

I've tuned specific areas in the model to attempt to change the vocabulary usage, while keeping as much intelligence as possible. So this is definitely not a LoRA , but also not exactly a proper full finetune , but rather something in-between .

As I mentioned in a small update , I've made nice progress regarding interesting sources of data, some of them are included in this tune. 100m tokens is a lot for a Roleplay / Adventure tune, and yes, it can do adventure as well—there is unique adventure data here, that was never used so far.

A lot of the data still needs to be cleaned and processed. I've included it before I did any major data processing, because with the magic of 24B parameters, even "dirty" data would work well, especially when using a more "balanced" approach for tuning that does not include burning the hell of the model in a full finetune across all of its layers. Could this data be cleaner? Of course, and it will. But for now, I would hate to make perfect the enemy of the good.

Fun fact: Impish_Magic_24B is the first roleplay finetune of magistral ! RP_magistral

Update: To my very pleasant surprise, it does Adventure really well

This was one of the goals, of course, but as I said, the data didn't go through enough cleaning and processing. Despite that, it turned out really well. Regarding the Adventure format, I strongly recommend using syntax similar to the attached adventure cards .


What's magical about Impish_Magic_24B?

Read more here .

I treat people's requests/feedback seriously , especially when it is well articulated and made with effort. Three months ago, there was a reddit thread named "Has anyone had any actual good fight-RP's?" I said in my comment that it is on my bucket list , and I meant it .

Indeed, there was none —there was no training data in this highly specific domain, until now . While I've included such data in Impish_Magic_24B , as mentioned earlier, the data is not perfect. It's quite the ordeal to get good data in the first place, and a whole other order of magnitude difficulty to clean and prep it.

There are a couple of additional magical things in Impish_Magic_24B : some completely unhinged tsundere / yandere RP with very high quality, and a lot more goodies that are completely new, as well as some VERY high quality adventure data, specifically for Morrowind / Kenshi and some more. While the data is very good, it's unfortunately quite small, to be completely honest, it is far from being enough in my opinion, and I am working on making more of it. A lot of work will need to be done in the future to make it more impactful, there are no shortcuts here. I hope this dataset gave just enough threads for the base model to do the rest of the heavy lifting.

So, is this just another RP model?

No . Far from it. Impish_Magic_24B is a superb assistant—it is quite magical indeed. One of my side projects has been to make an alternative to an especially annoying grammar app I keep seeing YouTube commercials for. So, I made the first finetune of nVidia's Nemotron-51B , and called it Turbo_Grammar_51B_Alpha . It worked as a POC, but I needed more training data, and also 51B is a bit big for most people. So I included the extended training data into this model, easily runnable by a mid-tier gaming GPU. Note: While this is enough data to generalize, a lot more data is needed for more consistant results, this is on my roadmap.

There's quite a lot of unique assistant data baked into this model—it can do in-depth poem analysis, and many other things. I'll leave it up to the community to discover. To not be overly cryptic, I'll include some examples here. I highly recommend you check them out, and have a bit of fun with the prompts and generation settings.

One of the requests I received is to emulate the writing style of an arbitrary author. This is hard to do, but for a 24B size, Impish_Magic does it well. Of course, more training data and more parameters would've produced even better results, but I feel it's a good middle ground. Impish_Magic_24B is a workhorse, that as it so happens can also roleplay a violent tsundere and... other weird stuff. Oh, and there's slightly less positivity bias. I think the fighting roleplay helped here a bit. It's not Negative_LLAMA_70B , but it's better than the base model.

TL;DR
  • The first and only local RP model at this size class with detailed and highly specialized fighting data . At least for now.
  • Completely wild tsundere / yandere data that was never used before!
  • New and high quality adventure data , albeit very little of it.
  • Perfect size : large enough to be smart, small enough to run on high-end tablets & phones ( SD8Gen3 or better recommended). Runs on 16GB VRAM no problem. 12GB with offload. (4bit).
  • Trained on over 100m tokens with new and unique data.
  • SUPERB assistant , many unique ways to do tasks (see examples).
  • Mostly uncensored while retaining intelligence.
  • Slightly less positivity . I guess getting hit in the face beats out some of the positivity. Sorry, I had to 🙃.
  • Short - medium length response (1-3 paragraphs, usually 2-3).

Roleplay settings: A good repetition_penalty range is between 1.12 - 1.15 , feel free to experiment.

With these settings, each output message should be neatly displayed in 1 - 5 paragraphs, 2 - 3 is the most common. A single paragraph will be output as a response to a simple message ("What was your name again?").

min_P for RP works too but is more likely to put everything under one large paragraph, instead of a neatly formatted short one. Feel free to switch in between.
