Model Summary

We present KARINA, finetuned from BLOOMZ bigscience/bloomz-3b, a family of models capable of following human instructions in dozens of languages zero-shot. We finetune BLOOMZ pretrained multilingual language models on our crosslingual task mixture (xP3) and find the resulting models capable of crosslingual generalization to unseen tasks & languages.

Use

Intended use

We recommend using the model to perform tasks expressed in natural language. For example, given the prompt "prompt = f"Given the question:\n{{ siapa kamu? }}\n---\nAnswer:\n"", the model will most likely answer "Saya Karina. Ada yang bisa saya bantu?".

# pip install -q transformers

MODEL_NAME = "yodi/karina"

tokenizer = AutoTokenizer.from_pretrained(MODEL_NAME)
model = AutoModelForCausalLM.from_pretrained(MODEL_NAME)

inputs = tokenizer.encode("Given the question:\n{{ siapa kamu? }}\n---\nAnswer:\n", return_tensors="pt")
outputs = model.generate(inputs)
print(tokenizer.decode(outputs[0]))

Infer in Local with Gradio

from transformers import AutoModelForCausalLM, AutoTokenizer
from transformers import pipeline
import re

import gradio as gr

MODEL_NAME = "yodi/karina"

model_4bit = AutoModelForCausalLM.from_pretrained(MODEL_NAME, device_map="cuda:1", load_in_4bit=True)
tokenizer = AutoTokenizer.from_pretrained(MODEL_NAME)

generator = pipeline('text-generation',
                     model=model_4bit,
                     tokenizer=tokenizer,
                     do_sample=False)

def preprocess(text):
    return f"Given the question:\n{{ {text} }}\n---\nAnswer:\n"

def generate(text):
    preprocess_result = preprocess(text)
    result = generator(preprocess_result, max_length=256)
    output = re.split(r'\n---\nAnswer:\n',result[0]['generated_text'])[1]

    return output

with gr.Blocks() as demo:
    input_text = gr.Textbox(label="Input", lines=1)
    button = gr.Button("Submit")
    output_text = gr.Textbox(lines=6, label="Output")
    button.click(generate, inputs=[input_text], outputs=output_text)

demo.launch(enable_queue=True, debug=True)
