Welcome to the world of Jais-30b, a sophisticated 30 billion parameter bilingual large language model (LLM) designed to facilitate seamless interactions in both Arabic and English. This model is not just an upgrade; it’s built on a rich dataset containing an impressive array of 126 billion Arabic tokens, 251 billion English tokens, and 50 billion code tokens. It uses advanced architecture and cutting-edge techniques to deliver precise context handling and impressive output quality. Whether you’re a researcher, developer, or commercial user, this guide will help you navigate the exciting possibilities offered by Jais-30b.

What Makes Jais-30b Stand Out?

Jais-30b utilizes a transformer-based decoder-only architecture resembling that of GPT-3, integrating SwiGLU non-linearity for enhanced performance. One of its significant features is the implementation of ALiBi position embeddings, which empowers the model to handle long sequences effectively. Just imagine a vast library where every book is perfectly indexed; the model can quickly find the relevant information without losing context over long passages.

How to Get Started

To harness the power of Jais-30b, you’ll need to set up your environment. Below is a sample code to help you get started with the model. Please ensure that you have the required libraries installed and are using the specified version of transformers (4.32.0).

python
# -*- coding: utf-8 -*-
import torch
from transformers import AutoTokenizer, AutoModelForCausalLM

model_path = 'core42/jais-30b-v1'
device = 'cuda' if torch.cuda.is_available() else 'cpu'

tokenizer = AutoTokenizer.from_pretrained(model_path)
model = AutoModelForCausalLM.from_pretrained(model_path, device_map='auto', trust_remote_code=True)

def get_response(text, tokenizer=tokenizer, model=model):
    input_ids = tokenizer(text, return_tensors='pt').input_ids
    inputs = input_ids.to(device)
    input_len = inputs.shape[-1]
    generate_ids = model.generate(
        inputs,
        top_p=0.9,
        temperature=0.3,
        max_length=200,
        min_length=input_len + 4,
        repetition_penalty=1.2,
        do_sample=True,
    )
    response = tokenizer.batch_decode(
        generate_ids, skip_special_tokens=True, clean_up_tokenization_spaces=True
    )[0]
    return response

text = 'عاصمة دولة الإمارات العربية المتحدة ه'
print(get_response(text))
text = 'The capital of UAE is'
print(get_response(text))

Code Walkthrough: An Analogy

Think of using Jais-30b as preparing a gourmet meal. Each ingredient (or line of code) contributes to the final dish:

• The import statements are like gathering all your ingredients from the pantry. You need to have everything ready before you start cooking.
• The tokenizer is your sous-chef, chopping and prepping the text so that it can be used efficiently. It converts human language into a format the model can digest.
• The model itself is the master chef, combining all the prepared ingredients (input data) while adjusting flavors (through parameters like top_p and temperature) to serve a delectable response.
• Finally, when we plate the dish with print(get_response(text)), it’s like serving the meal to guests, ready for taking their feedback!

Troubleshooting and FAQs

Like any sophisticated tool, Jais-30b may present some challenges. Here are common issues and how to address them:

• Issue: The model doesn’t load or gives an error about remote code.
• Solution: Make sure you have set trust_remote_code=True when loading the model. This allows your application to trust the code coming from the model repository.
• Issue: The output is not in the expected language or format.
• Solution: Double-check the text input to ensure it is appropriately formatted and in either Arabic or English. Retain focus on the language used based on your tokenizer.
• Issue: Performance is lagging or crashing.
• Solution: Ensure that your hardware meets the model’s requirements. If running on CPU, consider whether you have sufficient RAM to handle the model’s parameters.
