Ult1.0

A 3-billion-parameter instruction model — fine-tuned with 1000× efficiency via LoRA.

Built on Qwen2.5-3B-Instruct, Ult1.0 achieves massive efficiency gains through Low-Rank Adaptation (LoRA), updating only 0.12% of parameters while preserving the base model's full capability.

GGUF (CPU-Optimized) Inference

The repository includes a Q8_0 quantized GGUF file for ultra-fast CPU inference with llama.cpp, Ollama, LM Studio, or any GGUF-compatible runner:

File	Size	Format	Quality
Ult1.0-Q8_0.gguf	3.29 GB	Q8_0 (8-bit)	Near-lossless

llama.cpp

./llama-cli -m Ult1.0-Q8_0.gguf -p "Write a poem about AI" -n 256

Ollama (import from GGUF)

ollama create ult1.0 -f Modelfile
# Modelfile content: FROM ./Ult1.0-Q8_0.gguf
ollama run ult1.0

Python (llama-cpp-python)

from llama_cpp import Llama
llm = Llama("Ult1.0-Q8_0.gguf", n_ctx=32768)
output = llm("Write a poem about AI", max_tokens=256)
print(output["choices"][0]["text"])

Transformers (GPU) Inference

from transformers import AutoModelForCausalLM, AutoTokenizer

model = AutoModelForCausalLM.from_pretrained("teolm30/Ult1.0", device_map="auto")
tokenizer = AutoTokenizer.from_pretrained("teolm30/Ult1.0")

messages = [{"role": "user", "content": "Explain quantum computing simply"}]
text = tokenizer.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
inputs = tokenizer(text, return_tensors="pt").to(model.device)
outputs = model.generate(**inputs, max_new_tokens=256)
print(tokenizer.decode(outputs[0], skip_special_tokens=True))
