Aether 2.3 represents a major milestone in the Aether model series, scaling up to the Qwen2.5-3B-Instruct base architecture. Trained with SFT (Supervised Fine-Tuning) via Hugging Face TRL and PEFT (LoRA) on a custom 3 GB dataset using local NVIDIA RTX GPU acceleration, Aether 2.3 offers significantly higher intelligence, broader contextual understanding, and superior multilingual responses in German and English.

Language(s) (NLP): German, English
License: Apache-2.0
Finetuned from model: Qwen/Qwen2.5-3B-Instruct

Uses

Direct Use

Aether 2.3 is designed for high-capability conversational AI, complex instruction following, creative text generation, and technical reasoning. Thanks to its LoRA adapter implementation, it delivers flagship 3B-class performance while remaining light enough to run efficiently on local hardware.

Quantized & GGUF Models

For standalone, CPU/GPU local execution without Python/Transformers dependencies, use the quantized GGUF binaries:

How to Get Started with the Model

Python (Transformers & PEFT)

Use the following Python code to load Aether 2.3 with transformers and peft:

python

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

base_model_id = "Qwen/Qwen2.5-3B-Instruct"
adapter_id = "Maxilicious20/Aether-2.3"

# Load Tokenizer and Base Model
tokenizer = AutoTokenizer.from_pretrained(base_model_id)
base_model = AutoModelForCausalLM.from_pretrained(
    base_model_id,
    torch_dtype=torch.bfloat16,
    device_map="auto"
)

# Load Aether 2.3 LoRA Adapter
model = PeftModel.from_pretrained(base_model, adapter_id)

# Example Prompt
messages = [
    {"role": "system", "content": "You are Aether 2.3, an advanced AI assistant."},
    {"role": "user", "content": "Hello! What improvements do you bring as a 3B model?"}
]

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=256)
print(tokenizer.decode(outputs[0][inputs.input_ids.shape[1]:], skip_special_tokens=True))
