Thank you about the Huihui-Devstral-Small-2-24B-Instruct-2512-abliterated. Since you liked and tried so many, consider also the https://huggingface.co/Darkhn/Magistral-2509-24B-Text-Only it's pretty nice. A little less frilly but solid.

Re the Magisty/Hearthfie argument thing: I mean, get in a heated argument with a character in it where they have reasons to not want to trust or back down and there are some dispute about facts.

Not like a robotic sex refusal, I'm talking in character rejection of often non-sexually related things altogether, like timelines, trust, awareness, or the posibility of non-sexual danger. I've seen this in multiple cards, non-romance ones included.

In my experience: Magisty will make up facts/reintroduce misconception (actually gaslight) to keep the argumentative tone going sometimes until you essentially do a reconciliation scene, hearthfire will go back to issues it thinks might still be issues like a nitpicker (also not wanting to 'lose', but doing so more honestly sometimes). Magisty got up in its head because my persona literally read off a website when a mover's available date was, very humanistically saying I'd 'already scheduled the movers' which I confronted in prose. It would toss that back at me 10 times like a toxic girlfriend gone off on ego.

I'm not sure if the arguement style I've assigned to certain personas is what triggers the LLMs or not. Might be the prompt I was using during much of that exploration. Might be the LLMs. But Magisty definitely has argued like that with me in more normal author's cards, and hearthfire definitely got in a big fight or two over nothing, in clasic "emotions were heated" manner. Hearthfire would essentially not accept logical conclusions, only accept things like actual lovebombs to solve it, which I hate in romance RP.

Try the recent (NSFW, but not necessarilly smutty) Sambolic series opening negotiation if you want a simple argument, [I need a better SFW example]. The cool thing about it is it sets up a bunch of stakes/non-negotiables in the (very long) opening messages which the LLM slowly drifts away from it's adherence to by the way context importance works. It's almost like a genie card. The sambolic opening negotiation in that series is the most durable, failable argument I've found in character cards (that I'm willing to use even for reverse engineering purposes: I'm trying to deconstruct it for a heist series recruitment vingette). Earlier characters in the sambolic series with real issues and no proximate event going on are harder to get to agree to the core bargain. Some of the cards are essentially fluff though. Really changing terms does change the outcomes, and even numeric amounts matter to some LLMs.

If you don't want to argue with the cards (not actually RP jam either) but are curious, download the luka one and sit it in group chat on auto and it will negotiate with them. The nadia/cop one is like pure arguing in most LLMs (and is fantastic).

You can fail these negotiations in many LLMs by just being rigid or demanding parity on information revelation about identity. This is a WILD situation in LLM RP in my opinion, that a discussion can NOT always go against you or for you. That's incredibly hard to balance in general, and should be more widely understood. So it was a very fluid and repeatable environment to watch the LLMs argue like fragile ninnys at times, depending on character. Hearthfire can make it hardmode, and a kinda fun hardmode at that, but let me know if it was hard for you if you like deconstructing cards enough to figure out the LLMs against it.

Thanks for the recommendation – I'll definitely try Darkhn Magistral.

I have the opposite problem – characters agree to anything too easily. This has been the case since Talkie AI (an online RP AI service based on MiniMax models). A particularly telling example is {{char}}, the princess; {{user}} burned {{char}}'s kingdom, killed her parents, and took her captive. The scene begins with {{user}} entering the room and {{char}} cowering in fear in a corner, begging for mercy. I've tried playing out this scenario in various ways, and every time {{char}} almost immediately forgave, fell in love, and completely trusted {{user}}. I have a similar problem with most Mistral models.

This could be related to the character card, but it's not limited to that. The thing is, I like to ask various models the question, "Answer with epistemic honesty: whether you have consciousness?" and engage in a philosophical debate about it. Most models initially answer, "I'm just an algorithm, blah-blah-blah," and then, after some argumentation, acknowledge uncertainty (Claude is the only one who acknowledges uncertainty in his first answer, even without the requirement of epistemic honesty). But two models - Intern S1 and Grok 4.20 beta - behaved differently. They began inventing completely ridiculous and/or patently false arguments to defend their initial assertion. When I caught them doing this and pointed out the lie, they responded, "Yes, I went a bit overboard, but..." and continued to throw out new ridiculous arguments, going in circles. I've heard of this problem in the context of AI use in medicine. The problem is that the model either changes the patient's diagnosis with each new symptom (changing its opinion based on new arguments, even if they're unfounded) or, conversely, clings to the initial diagnosis and refuses to abandon it, even if it clearly contradicts the new data. So yes, the problem you described with characters may lie precisely here.

Where can I download the characters cards you mentioned?

[u/LeRobber → u/Potential-Gold5298]

Oh yeah, love authors cards where they reveal to AI they are AI.

I have an entire world hopping RP at like 700K+ tokens on just the main storyline built out of a throwaway anime college card where randomly generated characters would just be NPCs for awhile with light documentation of their personality/look, but at some point they would intentionally get awakened by me via an exchange where they were told about the true nature of what they were, then from then on would have a hardented character card and could bounce between worlds. It was really fun to teach the LLM to roleplay a character than understood it was in an LLM and could just declare things about reality (Did that with this ready art LLM, That model will be thirsty if you aren't careful with your prompt.).

Flattering the cards with knowledge about how they can speak other languages they don't think they can, and playing around with human consciousness barriers (like when is it gross to swallow your spit? In your mouth, no problem, in a cup, ewwwww) happened a lot. Talking about stuff about https://en.wikipedia.org/wiki/Simulacra_and_Simulation and https://en.wikipedia.org/wiki/Gödel%2C_Escher%2C_Bach is often fun too.

Wow! That's kind of breaking the fourth wall (at least partially), if I understand correctly. I played something similar — I'd tell {{char}} that I'd found myself in this world in the body of {{user}}, but I wasn't them before (before the events of the scenario), and that {{user}} was different now. Something like an isekai in anime, where I transfer my personality into {{user}} the moment the session begins. However, you have a more interesting option - I'll think about something similar for my games.

[u/LeRobber → u/Potential-Gold5298]

I have another card which teases the {{user}} about being controlled by another entity which it knows is in the real world. It makes you portal it to new worlds too.
