Model Card for RigoChat-7b-v2

RigoChat-7b-v2 is a Qwen-2.5-based model specifically designed to provide accurate responses from Spanish queries. Specifically, is based on the Qwen/Qwen2.5-7B-Instruct model and has been fine-tuned with Direct Preference Optimization (DPO) for improved performance in Spanish language.

This model is licensed for non-commercial use. If you want to use it commercially, please contact us or use it through the service we offer from the AWS Marketplace.

Model Details

Model Description

This model is the second version of RigoChat, a family of Large Language Models (LLMs) designed to solve typical NLP tasks with Spanish instructions such as: Tool Use, Summarization, Math, Code, Abstractive-QA, etc. Like Qwen/Qwen2.5-7B-Instruct, this model has no specific use case and can be applied to a wide range of tasks. Indeed, it offers a slight improvement for generalist tasks in Spanish, particularly in RAG (Retriever Augmented Generation) systems with Spanish databases, as its training focused on resolving questions about contexts to prevent hallucinations and ensure safety responses.

Key benefits of this model include:

Improved performance on generalist tasks in Spanish.
Enhanced safety and reduced hallucinations in RAG systems with Spanish texts.
Possibility of using it in different hardware requirements, especially those with reduced computational capacity. For more information on how to use RigoChat-7b-v2 on reduced hardware, see IIC/RigoChat-7b-v2-GGUF.

Remarkably, this model was trained on a single A100 GPU with limited computational resources, yet achieved its current state in a relatively short time (8.5 hours). This feat was made possible by leveraging a high-quality dataset and employing advanced techniques such as LoRA to optimize memory usage. Further details on the training process can be found below.

Developed by: Instituto de Ingeniería del Conocimiento (IIC).
Model type: Generative Fine-tuned Transformer.
Language(s) (NLP): Spanish (BCP-47 es).
License: RIGOCHAT 2 NON-COMMERCIAL.
Finetuned from model: Qwen/Qwen2.5-7B-Instruct.

Uses

Direct Use

You can use and deploy RigoChat-v2 for commercial purposes through a model package from AWS Marketplace. You can check the instructions inside the following notebook.

Out-of-Scope Use

This language model has been adapted for general natural language processing tasks in Spanish and specific use cases such as RAG. However, there are several cases where the model should not be used due to its technical and ethical limitations:

Illegal Activities: The model should not be used to generate content related to illegal activities, such as creating malicious software, fraud, incitement to crime, or any illegal material.
Harmful or Dangerous Content: It should not be used to generate hate speech, violence, harassment, or any content that promotes discrimination, violence, or abuse.

Bias, Risks, and Limitations

Although this model has been trained to understand and generate text in Spanish, there are several risks, biases, and limitations that users should be aware of:

Biases: The model may reflect biases present in the training data. These biases could be related to gender, race, social class, sexual orientation, among others, and may generate responses that perpetuate stereotypes or discrimination.
Accuracy and Reliability: While the model generates coherent and useful text in many contexts, it may not always be 100% accurate or reliable, especially in technical, scientific, or legal matters where high certainty is required.
Limited or Outdated Knowledge: The model is not trained with information beyond its training cutoff date. Therefore, it may not reflect recent events, research, or advancements.

Recommendations

We recommend using this model as a general chatbot or within applications designed for specific tasks, such as SQL queries, RAG systems, or as an autonomous agent to facilitate the use of tools.

How to Get Started with the Model

As Qwen/Qwen2.5-7B-Instruct or any model that uses the chatml template.

To load the model and tokenizer

from transformers import (
    AutoModelForCausalLM,
    AutoTokenizer,
)
import torch

model_name = "IIC/RigoChat-7b-v2"

model = AutoModelForCausalLM.from_pretrained(
    model_name,
    torch_dtype=torch.bfloat16,
    device_map="cuda",
    trust_remote_code=True,
)
tokenizer = AutoTokenizer.from_pretrained(
    model_name,
    trust_remote_code=True,
)

Sample generation

messages = [
    {"role": "user", "content": "¿Cómo puedo transformar un diccionario de listas en una lista de diccionarios, y viceversa, en Python sin utilizar bucles for?"}
]

text = tokenizer.apply_chat_template(
    messages,
    tokenize=False,
    add_generation_prompt=True,
)
model_inputs = tokenizer([text], return_tensors="pt").to(model.device)

generated_ids = model.generate(
    **model_inputs,
    max_new_tokens=1024,
)
generated_ids = [
    output_ids[len(input_ids):] for input_ids, output_ids in zip(model_inputs.input_ids, generated_ids)
]

response = tokenizer.batch_decode(generated_ids, skip_special_tokens=True)[0]

For a better experience, we recommend to use the following generation parameters.

Tool Use

def get_current_weather(location: str, date: str) -> float:
    """
    Obtener la datos del tiempo de una localización.
    
    Args:
        location: La locaización, con el siguiente formato: "Ciudad, País."
        date: La fecha, en el formato AAAA-MM-DD.
    Returns:
        El tiempo en dicha localización.
    """
    return {"temperatura": 22, "cielo": "nublado", "probabilidad de lluvias": "60%"}

messages = [
  {"role": "user", "content": "Este fin de semana quiero visitar Madrid, y no se qué ropa llevarme. ¿Podrías decirme qué tal va a hacer? Es el puente del 6 de diciembre de 2024."}
]

text = tokenizer.apply_chat_template(
    messages,
    tokenize=False,
    tools=[get_current_weather],
    add_generation_prompt=True
)
model_inputs = tokenizer([text], return_tensors="pt").to(model.device)

generated_ids = model.generate(
    **model_inputs,
    max_new_tokens=1024
)
generated_ids = [
    output_ids[len(input_ids):] for input_ids, output_ids in zip(model_inputs.input_ids, generated_ids)
]

response = tokenizer.batch_decode(generated_ids, skip_special_tokens=True)[0]

Training Details

Training Data

A combination of both public and private datasets designed in the IIC. The dataset consists of 21975 conversations in Spanish, with the format chatml and has the same structure as the Anthropic/hh-rlhf dataset. Each conversation has two variants: chosen and rejected, and only differs the last answer of the assistant. The last answer in the chosen variant is considered a better answer than the one in the rejected variant. Different techniques have been used to generate the dataset, which we explain in depth in the research (coming soon).

Training Procedure

We use the Transformer Reinforcement Learning (TRL) library. Specifically, we have applied the script they have published as an example for using DPO to the dataset we have generated.
