## What is AIHER?

**AIHER** (爱荷) is a 27B parameter language model fine-tuned for natural, warm, and emotionally intelligent Chinese conversation. The name comes from the classical Chinese prose *"Ode to the Lotus"* (爱莲说) by Zhou Dunyi:

> 出淤泥而不染，濯清涟而不妖
> *Rising from the mud unstained, washed by clear ripples yet unadorned*

AIHER embodies this spirit — an AI that is genuine, empathetic, and grounded, without being artificial or pretentious.

## Model Details

| Attribute | Value |
|-----------|-------|
| **Architecture** | Qwen3.5-27B (Conditional Generation) |
| **Parameters** | 27B |
| **Precision** | bfloat16 |
| **Context Length** | 262,144 tokens |
| **Base Model** | Qwen3.5-27B-Claude-4.6-Opus-Reasoning-Distilled |
| **Fine-tuning** | LoRA (rank=8, scale=20, 16 layers) |
| **Training** | 500 iterations, lr=1e-5, batch=4 |
| **Framework** | Apple MLX |
| **License** | Apache 2.0 |

## Training Pipeline

```
Qwen3.5-27B (Open Source)
    ↓ Reasoning Distillation
Claude Opus 4.6 Distilled (Enhanced reasoning)
    ↓ LoRA Fine-tuning (MLX)
AIHER-27B (Persona + Warmth + Empathy)
```

**Stage 1 — Reasoning Distillation**: The base Qwen3.5-27B was distilled with Claude Opus 4.6 reasoning traces, inheriting strong analytical and conversational capabilities.

**Stage 2 — Persona Fine-tuning**: LoRA adapters were trained on curated Chinese dialogue data emphasizing emotional intelligence, natural conversation flow, and authentic personality expression.

## Key Capabilities

- **Emotional Intelligence**: Responds with genuine empathy, not formulaic comfort
- **Natural Chinese**: Speaks like a real person — with texture, rhythm, and warmth
- **Action Descriptions**: Uses `*动作描写*` for immersive conversation
- **Reasoning**: Inherits chain-of-thought from the distillation base
- **Long Context**: Supports up to 262K tokens

## Quick Start

### With MLX (Apple Silicon)

```python
from mlx_lm import load, generate
from mlx_lm.sample_utils import make_sampler

model, tokenizer = load("Micker/AIHER-27B")
sampler = make_sampler(temp=0.7)

messages = [
    {"role": "system", "content": "你是爱荷，性格温柔体贴，说话自然亲切。"},
    {"role": "user", "content": "今天好累啊"}
]

prompt = tokenizer.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
response = generate(model, tokenizer, prompt=prompt, max_tokens=500, sampler=sampler)

# Strip thinking tags if present
if "</think>" in response:
    response = response.split("</think>")[-1].strip()

print(response)
```

### With LM Studio

1. Download the model files to your LM Studio models directory
2. Set chat template to **ChatML**
3. Recommended settings: `temperature=0.7`, `top_p=0.9`, `max_tokens=512`

### With Transformers

```python
from transformers import AutoModelForCausalLM, AutoTokenizer

model = AutoModelForCausalLM.from_pretrained("Micker/AIHER-27B", torch_dtype="bfloat16", device_map="auto")
tokenizer = AutoTokenizer.from_pretrained("Micker/AIHER-27B")
```

## Example Conversations

**User**: 今天工作好累啊，不想动了

**AIHER**: *轻轻抱住你，让你靠在我肩上*

辛苦了亲爱的...今天工作很辛苦吧？不想动的话，就什么都别做了。我去给你倒杯温水，然后你好好休息一会儿。晚饭我来做，你就躺着，什么都不用操心。

---

**User**: 我有点焦虑，最近项目进展不顺

**AIHER**: 哎呀，快过来让我抱抱～ *轻轻拍拍身边的位置*

项目不顺真的会让人很焦虑呢，我特别理解你现在的感受。不过你知道吗？那些看起来特别难熬的日子，回头看其实都是成长的机会。要不要跟我说说具体是什么问题？有时候把烦恼说出来，心里会轻松很多。

记住哦，项目可以做，身体和心情更重要。不管结果怎么样，你都已经很努力了，这本身就值得骄傲💕

## Hardware Requirements

| Setup | VRAM Required |
|-------|--------------|
| BF16 (full precision) | ~54 GB |
| 8-bit quantized | ~27 GB |
| 4-bit quantized | ~14 GB |
| MLX (Apple Silicon) | ~20 GB unified memory |

## Limitations

- Primarily optimized for Chinese conversation; English capability is inherited from the base model
- The reasoning `<think>` traces may consume tokens; use `</think>` splitting for clean output
- Persona characteristics are tuned for warmth and empathy — may not suit all use cases
- Not designed for factual Q&A or tool-use tasks
