Open In Colab

Stambecco 13B Plus is an Italian instruction-following Parameter-Efficient Fine-Tuning (PEFT) adapter based on Meta's LLaMA-13B architecture.

It was trained on the Stambecco Plus Dataset, an Italian instruction dataset traslated from Alpaca-GPT4 (GPT-4-LLM), a dataset distilled directly from GPT-4. As a result, this model offers superior Italian reasoning, vocabulary, and response quality compared to standard GPT-3.5-based models.

GitHub Project: mchl-labs/stambecco
Dataset Used: mchl-labs/stambecco_data_plus_it
Model Type: PEFT / LoRA Adapter Delta

🚀 Quickstart & Usage

This repository contains the LoRA adapter weights (delta). To run inference, load these weights on top of the base LLaMA-13B model using Hugging Face's transformers and peft libraries:

python

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

base_model_name = "decapoda-research/llama-13b-hf"  # Base LLaMA-13B weights
adapter_name = "mchl-labs/stambecco-13b-plus"        # This adapter

# 1. Load Tokenizer & Base Model
tokenizer = AutoTokenizer.from_pretrained(base_model_name)
base_model = AutoModelForCausalLM.from_pretrained(
    base_model_name,
    torch_dtype=torch.float16,
    device_map="auto"
)

# 2. Load Stambecco LoRA Adapter
model = PeftModel.from_pretrained(base_model, adapter_name)

# 3. Generate Output
prompt = "### Istruzione:\nSpiega come funziona l'intelligenza artificiale in modo semplice.\n\n### Risposta:\n"
inputs = tokenizer(prompt, return_tensors="pt").to("cuda")

with torch.no_grad():
    outputs = model.generate(**inputs, max_new_tokens=256, temperature=0.7)

print(tokenizer.decode(outputs[0], skip_special_tokens=True))

💡 Try it in Colab: You can also run interactive chat directly in Google Colab using our Inference Notebook.

⚠️ Intended Uses & Safety Disclaimer

Research Use Only: Consistent with Stanford Alpaca and Meta's original LLaMA license, Stambecco is intended strictly for academic and non-commercial research purposes. Commercial or production usage is strictly prohibited.
Content Risk Warning: Like many instruction-tuned LLMs, model outputs may contain inaccuracies, hallucinations, biased language, or inappropriate content. Output should be critically evaluated by human reviewers.
