# MN-12B-Hydra-RP-RU

<details>
<summary>🇷🇺 Нажмите, чтобы развернуть описание на русском</summary>

## 🌟 О модели

**MN-12B-Hydra-RP-RU** — экспериментальный merge на базе Mistral Nemo 12B, сочетающий:

* 🎭 Сильные ролевые способности
* 📚 Глубокий литературный русский язык
* 🔓 Снятую цензуру

Модель собрана методом TIES-merging, что позволяет объединять веса нескольких моделей с минимальными конфликтами между параметрами.

## 🎯 Особенности

* Основной язык — русский
* Хорошо держит персонажей и контекст
* Следует инструкциям
* Сохраняет возможности базового Nemo
* Не проходила дополнительного обучения после слияния

## ⚠️ Важно

Uncensored-характер модели означает, что она может генерировать контент, который некоторые пользователи сочтут неподобающим.

</details>

High-quality TIES merge based on **Mistral Nemo 12B**, optimized for roleplay, strong Russian language capabilities, and uncensored behavior.

## 🌍 Overview

**MN-12B-Hydra-RP-RU** is an experimental merge built on top of [Mistral Nemo 12B](https://huggingface.co/mistralai/Mistral-Nemo-Base-2407), combining strengths from multiple fine-tuned models:

* 🎭 Advanced roleplay capability from Pathfinder-RP
* 📚 Deep Russian language fluency inspired by Vikhr + Dostoevsky-style tuning
* 🔓 Reduced safety filtering via uncensored components

The merge was created using **TIES merging**, which allows combining model deltas while minimizing destructive interference between weights.

## 💡 Usage Example

```python
from transformers import AutoTokenizer, AutoModelForCausalLM
import torch

model_name = "limloop/MN-12B-Hydra-RP-RU"
tokenizer = AutoTokenizer.from_pretrained(model_name)
model = AutoModelForCausalLM.from_pretrained(
    model_name,
    torch_dtype=torch.bfloat16,
    device_map="auto"
)

prompt = "You are a medieval innkeeper. Greet the traveler!"
messages = [{"role": "user", "content": prompt}]
inputs = tokenizer.apply_chat_template(messages, return_tensors="pt").to(model.device)

outputs = model.generate(inputs, max_new_tokens=512, temperature=0.7)
response = tokenizer.decode(outputs[0], skip_special_tokens=True)
print(response)
```

## ⚙️ Merge Details

Built using [mergekit](https://github.com/cg123/mergekit) with the **TIES** method (Trim, Elect Sign, Merge).

Core mechanism:

1. Trim low-magnitude deltas via `density`
2. Resolve sign conflicts
3. Weighted averaging of aligned parameters
