The Mistral-7B-v0.1-Adapted collection of large language models (LLMs), is a collection of adapted generative models in 7B (text in/text out), adapted models from Mistral-7B-Base-v0.1.

Mistral-v0.1-Italian-SAVA is a continually trained Mistral model, after tokenizer substitution.

The tokenizer of this models after adaptation is the same of Minverva-3B.

Model developer: SapienzaNLP, ISTI-CNR, ILC-CNR

Model Architecture: Mistral-7B-v0.1-Adapted is an auto-regressive language model that uses an optimized transformer architecture.

Data used for the adaptation

The Mistral-7B-v0.1-Adapted model are trained on a collection of Italian and English data extracted from CulturaX. The data are extracted to be skewed toward Italian language with a ration of one over four. Extracting the first 9B tokens from Italian part of CulturaX and the first 3B tokens from English part of CulturaX.

Use with Transformers

You can run conversational inference using the Transformers pipeline abstraction or by leveraging the Auto classes with the generate() function.

Make sure to update your transformers installation via pip install --upgrade transformers.

python

import transformers
import torch

model_id = "SemanticAlignment/Mistral-v0.1-Italian-SAVA"

pipeline = transformers.pipeline(
    "text-generation", model=model_id, model_kwargs={"torch_dtype": torch.bfloat16}, device_map="auto"
)

pipeline("Cosa si può fare in una bella giornata di sole?")
