Description

Zenos GPT-J 6B Alpaca Evol 4-bit is a Spanish Instruction capable model based on the GPT-J architecture with 6 billion parameters. It has been fine-tuned on the Alpaca Spanish and Evol Instruct datasets, making it particularly suitable for natural language understanding and generation tasks in Spanish.

Requirements

The following specific versions are required in order to load and/or manipulate the present model. At least, until the existing PRs are approved. They allow saving and loading 4 bits model, with LoRa adapters included.

Since this is a compressed version (4 bits), it can fit into ~7GB of VRAM.

Usage

You can use this model for various natural language processing tasks such as text generation, translation, summarization, and more. Below is an example of how to use it in Python with the Transformers library:

from transformers import AutoTokenizer, AutoModelForCausalLM, GenerationConfig

# Load the tokenizer and model
tokenizer = AutoTokenizer.from_pretrained("zenos-gpt-j-6B-alpaca-evol-4bit")
model = AutoModelForCausalLM.from_pretrained("zenos-gpt-j-6B-alpaca-evol-4bit")

# Generate text
prompt = 'A continuación hay una instrucción que describe una tarea. Escribe una respuesta que complete adecuadamente lo que se pide.\n\n### Instrucción:\nEscribe un poema breve usando cuatro estrofas\n\n### Respuesta:\n'

inputs = tokenizer(prompt, return_tensors="pt")
input_ids = inputs["input_ids"].to(model.device)
attention_mask = inputs["attention_mask"].to(model.device)

generation_config = GenerationConfig(
    temperature=0.1,
    top_p=0.75,
    top_k=40,
    num_beams=1,
    repetition_penalty=1.5,
    do_sample=True,
    
)
with torch.no_grad():
    generation_output = model.generate(
        input_ids=input_ids,
        pad_token_id=tokenizer.eos_token_id,
        attention_mask=attention_mask,
        generation_config=generation_config,
        return_dict_in_generate=True,
        output_scores=False,
        max_new_tokens=512,
        early_stopping=True
    )

s = generation_output.sequences[0]
output = tokenizer.decode(s)
start_txt = output.find('### Respuesta:\n') + len('### Respuesta:\n')
end_txt = output.find("<|endoftext|>", start_txt)
answer = output[start_txt:end_txt]

print(answer)

Inference

Currently, the HuggingFace's Inference Tool UI doesn't properly load the model. However, you can use it with regular Python code as shown above once you meet the requirements.
