+
+## 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
