# Aether 2.5 Pro

Aether 2.5 Pro is the strongest model in the Aether 2.5 series so far.  
It is a fine-tuned version of **Qwen2.5-3B-Instruct**, trained with TRL + PEFT (LoRA) on a higher-quality and more diverse dataset than previous versions.

Compared to the standard Aether 2.5, the Pro version offers:
- Better reasoning
- Improved instruction following
- Stronger multilingual performance (German + English)
- Higher overall response quality while staying efficient for local use

## How to Use (Python)

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

base_model_id = "Qwen/Qwen2.5-3B-Instruct"
adapter_id = "Maxilicious20/Aether-2.5-Pro"

tokenizer = AutoTokenizer.from_pretrained(base_model_id)
base_model = AutoModelForCausalLM.from_pretrained(
    base_model_id,
    torch_dtype=torch.bfloat16,
    device_map="auto"
)

model = PeftModel.from_pretrained(base_model, adapter_id)

messages = [
    {"role": "system", "content": "You are Aether 2.5 Pro, a highly capable AI assistant developed by Mono AI Studio."},
    {"role": "user", "content": "Explain the difference between supervised and unsupervised learning in simple terms."}
]

prompt = tokenizer.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
inputs = tokenizer(prompt, return_tensors="pt").to(model.device)

outputs = model.generate(**inputs, max_new_tokens=512)
print(tokenizer.decode(outputs[0][inputs.input_ids.shape[1]:], skip_special_tokens=True))
