RakutenAI-7B
Rakuten
The RakutenAI-7B model is a large language model developed by Rakuten that achieves strong performance on Japanese language understanding benchmarks while also performing competitively on English test sets. It leverages the Mistral model architecture and is based on the Mistral-7B-v0.1 pre-trained checkpoint, exemplifying a successful retrofitting of the pre-trained model weights. The model also extends Mistral's vocabulary from 32k to 48k to offer better character-per-token rate for Japanese.
According to the provided benchmarks, RakutenAI-7B outperforms similar models like OpenCalm, Elyza, Youri, Nekomata, and Swallow on several Japanese language understanding tasks.
Model Inputs and Outputs
Inputs
The model accepts text input in Japanese and English.
Outputs
The model generates human-like text in Japanese and English.
Capabilities
The RakutenAI-7B model demonstrates strong performance on a variety of Japanese language understanding tasks, including JSNLI, RTE, KUCI, JCS, and JNLI. It also maintains competitive results on English test sets compared to similar models. Rakuten has further fine-tuned the foundation model to create the RakutenAI-7B-instruct and RakutenAI-7B-chat models for specific use cases.
What Can I Use It For?
The RakutenAI-7B model can be used for a variety of natural language processing tasks, such as text generation, language understanding, and translation between Japanese and English. Its strong performance on Japanese benchmarks makes it well-suited for applications targeting the Japanese market, such as customer service chatbots, content generation, and language learning tools.
Rakuten has also made available the RakutenAI-7B-instruct and RakutenAI-7B-chat models, which can be used for instruction-following and open-ended conversational tasks, respectively.
Things to Try
One interesting aspect of the RakutenAI-7B model is its ability to perform well on both Japanese and English tasks, making it a versatile model for multilingual applications. Developers could explore using the model for tasks that require understanding and generation in both languages, such as translation, cross-lingual information retrieval, or even building language learning tools that can adapt to the user's native language.
Another area to explore is the model's performance on various Japanese-specific tasks, such as sentiment analysis, text summarization, or question answering on Japanese-language data. Leveraging the model's strong performance on Japanese benchmarks could lead to interesting applications tailored to the Japanese market.
