Welcome to the world of advanced language processing with Sarashina2-7B! Developed by SB Intuitions, this powerful language model is built to generate meaningful text based on the input data provided. In this guide, we’ll walk through how to utilize the model, its configurations, and address potential troubleshooting scenarios to get you generating great content in no time.

Getting Started with Sarashina2-7B

To start using the Sarashina2-7B model, ensure you have Python installed along with the necessary libraries. Here’s a step-by-step guide:

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

# Load the model and tokenizer
model = AutoModelForCausalLM.from_pretrained("sbintuitions/sarashina2-7b", torch_dtype=torch.bfloat16, device_map="auto")
tokenizer = AutoTokenizer.from_pretrained("sbintuitions/sarashina2-7b")

# Optional: Using slow tokenizer
# tokenizer = AutoTokenizer.from_pretrained("sbintuitions/sarashina2-7b", use_fast=False)

# Create a text generation pipeline
generator = pipeline("text-generation", model=model, tokenizer=tokenizer)

# Set a random seed for reproducibility
set_seed(123)

# Generate text
text = generator(
    "おはようございます、今日の天気は",  # Input prompt in Japanese
    max_length=30,
    do_sample=True,
    pad_token_id=tokenizer.pad_token_id,
    num_return_sequences=3,
)

# Print generated text
for t in text:
    print(t)

Understanding the Code: An Analogy

Think of using the Sarashina2-7B model as hiring a talented chef (the model) to whip up delicious dishes (text) based on your recipe (input prompt). The steps are as follows:

• Importing Ingredients: You start by gathering necessary ingredients (libraries) that your chef needs to cook effectively.
• Preparing the Kitchen: Next, you set up your kitchen with proper tools (loading the model and tokenizer). You can choose to work with different cooking styles (slow vs. fast tokenizer).
• Creating a Recipe: You define what you want to cook by writing down a recipe (input prompt) that the chef can reference.
• Cooking Time: You give the chef instructions on how to prepare the dish (text generation process) and set a timer for expected results (max_length and seeds).
• Serving the Dish: Finally, you can present the delicious concoctions (generated text) for everyone to taste (output). Each dish can have its variations and surprises!

Configuration Details

Here’s a look at the parameters and specifications present in Sarashina2-7B:

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 datasets for Sarashina2-7B include:

• The Japanese portion of the Common Crawl corpus.
• English documents from SlimPajama, excluding the books3 corpus due to copyright issues.

Tokenization Process

For tokenization, we rely on a sentencepiece tokenizer that allows you to input raw sentences directly, without additional pre-tokenization for Japanese.

Ethical Considerations

It’s important to note that while Sarashina2 has significant capabilities, it may need further tuning to adhere to specific safety and instruction-following standards. Be prepared to refine its outputs to align with your needs.

Troubleshooting and FAQs

If you encounter issues or unexpected outputs while using the Sarashina2-7B model, consider the following:

• Overly vague outputs: Adjust your input prompts to be more specific or detailed.
• If the model crashes: Ensure your device has sufficient resources (GPU memory) and try running in a lower setting.
• For unsupported tokens or characters: Ensure your tokenizer is properly set up and it matches the expected input formats.
