Welcome to the world of AI language generation! In this blog, we’ll explore how to effectively utilize the Sarashina2-13B language model provided by SB Intuitions. Whether you’re a beginner or a seasoned developer, this guide is crafted for you.

Step-by-Step Instructions

Let’s walk through the process of implementing the Sarashina2-13B model in your project.

Step 1: Install Required Libraries

• Ensure you have Python installed.
• Install the required libraries using pip:

pip install torch transformers

Step 2: Import the Necessary Modules

Begin by importing the essential libraries:

import torch
from transformers import AutoModelForCausalLM, AutoTokenizer, pipeline, set_seed

Step 3: Load the Sarashina2-13B Model

In this step, we will load the model and the tokenizer:

model = AutoModelForCausalLM.from_pretrained("sbintuitions/sarashina2-13b", torch_dtype=torch.bfloat16, device_map="auto")
tokenizer = AutoTokenizer.from_pretrained("sbintuitions/sarashina2-13b")

Step 4: Generate Text

Now we can use the model to generate text! Here’s how:

generator = pipeline("text-generation", model=model, tokenizer=tokenizer)
set_seed(123)
text = generator("おはようございます、今日の天気は", max_length=30, do_sample=True, pad_token_id=tokenizer.pad_token_id, num_return_sequences=3)

Step 5: Print Generated Text

Finally, loop through the generated text and print each output:

for t in text:
    print(t)

Understanding the Code: A Helpful Analogy

Think of using the Sarashina2-13B model like baking a cake:

• Ingredients: You need to gather the right ingredients (libraries like torch and transformers).
• Baking Process: Loading the model is akin to preheating the oven—getting everything ready to create something delightful.
• Mixing Sweetness: Generating text is like mixing your batter; you’re combining input with the model to create a tasty output.
• Decoration: Finally, printing the generated text is like icing the cake—you beautifully present the end result for everyone to enjoy!

Configuration Overview

Below is a brief look at the configuration of the Sarashina2-13B model:

Parameters	Vocab size	Training tokens	Architecture	Position type	Layers	Hidden dim	Attention heads
7B	102400	2.1T	Llama2	RoPE	32	4096	32
13B	102400	2.1T	Llama2	RoPE	40	5120	40
70B	102400	2.1T	Llama2	RoPE	80	8192	64

Training Corpus

The training data consists of a combination of resources, including a part of the Common Crawl corpus for Japanese and extracted documents from SlimPajama for English. The data was meticulously cleaned to ensure high-quality output.

Tokenization Methodology

The tokenizer used is a SentencePiece tokenizer that allows users to directly input raw sentences, which simplifies the usage of this model significantly.

Ethical Considerations and Limitations

As with all AI models, Sarashina2 is not without its limitations. It may produce inaccurate outputs or biased content. Developers are encouraged to fine-tune the model based on human preferences for safer usage.

Troubleshooting

If you encounter issues while using the Sarashina2-13B model, consider the following:

• Ensure all libraries are correctly installed and updated.
• Double-check the code for syntactical errors or typos.
• If the model fails to generate meaningful text, consider retraining it with more diverse data.
