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

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

Download the model files to your LM Studio models directory
Set chat template to ChatML
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
