Welcome to the world of RakutenAI-7B, a state-of-the-art language model specifically designed for Japanese understanding, while also demonstrating impressive proficiency in English. This blog post will guide you through the setup and usage of RakutenAI-7B-Chat, ensuring you have a smooth experience with this powerful tool.

Model Overview

The RakutenAI-7B is not just another language model; it’s a well-thought-out project that has achieved top scores on Japanese language benchmarks. Utilizing the Mistral model architecture, it stands out among competitors like OpenCalm and Elyza. Furthermore, it features an enhanced vocabulary from 32k to 48k tokens, optimizing character-per-token rates for the Japanese script. You can find the detailed technical report on arXiv.

Getting Started

Before diving into usage, ensure you have the necessary setup for your environment. Here’s how to start:

• Install the required Python package Transformers.
• Prepare your environment with PyTorch and all dependencies.

Code Implementation

Now let’s get hands-on with some Python code! The following code snippet demonstrates how you can effectively utilize RakutenAI-7B-Chat:

python
from transformers import AutoModelForCausalLM, AutoTokenizer

model_path = "Rakuten/RakutenAI-7B-chat"
tokenizer = AutoTokenizer.from_pretrained(model_path)
model = AutoModelForCausalLM.from_pretrained(model_path, torch_dtype="auto", device_map="auto")
model.eval()

requests = ["How to make an authentic Spanish Omelette?"]
system_message = "A chat between a curious user and an artificial intelligence assistant. The assistant gives helpful, detailed, and polite answers to the user's questions."

for req in requests:
    input_req = system_message.format(user_input=req)
    input_ids = tokenizer.encode(input_req, return_tensors='pt').to(device=model.device)
    
    tokens = model.generate(
        input_ids,
        max_new_tokens=1024,
        do_sample=True,
        pad_token_id=tokenizer.eos_token_id,
    )
    
    out = tokenizer.decode(tokens[0][len(input_ids[0]):], skip_special_tokens=True)
    
    print("USER: " + req)
    print("ASSISTANT: " + out)
    print()

Understanding the Code

Think of RakutenAI-7B as a highly trained chef who knows a huge variety of recipes (knowledge). To get the chef to cook (generate responses), you need to provide an order (request) and the kitchen setup (model and tokenizer). Here’s how the code flows:

• You first introduce your chef (load the model).
• You give him a few instructions about cooking style (system message).
• You ask a question (input request).
• The chef processes the order and presents a dish (the generated response).

Troubleshooting

If you encounter any issues while using RakutenAI-7B-Chat, here are some troubleshooting tips to help you:

• Model Not Loading: Ensure that your environment is properly set up and that you’ve downloaded the model. Check your internet connection as well.
• Execution Errors: Verify that you have compatible versions of PyTorch and Transformers installed.
• Unexpected Outputs: Remember, models might generate nonsensical or biased outputs. Always review and adjust your input prompts accordingly.
