RakutenAI Models by Rakuten
Details
About
The RakutenAI family of large language models (LLMs) features advanced models primarily for Japanese language processing, with solid performance in English. The flagship model, RakutenAI-7B, is a 7-billion parameter model developed from the open-source Mistral-7B-v0.1, enhanced by training on a diverse dataset of Japanese and English texts. This training, executed on Rakuten's powerful GPU infrastructure, enables the model to excel in Japanese language tasks. The model's tokenizer is specifically optimized for Japanese characters, ensuring efficient processing. Alongside the foundation model, Rakuten offers instruction-tuned and chat-tuned versions, dubbed RakutenAI-7B-instruct and RakutenAI-7B-chat, for more task-specific applications. All models are open-source under the Apache 2.0 license and available on Hugging Face. However, users should be aware of potential biases and inaccuracies 11 10 12.

Frequently Asked Questions
- What is RakutenAI used for?
- RakutenAI is used for multilingual. The family description and listed model capabilities point to those workloads as the best fit.
- How does RakutenAI compare to Claude 3?
- RakutenAI by Rakuten is strongest where you need multilingual, while Claude 3 by Anthropic is the closest related family to check for vision and multimodal work. RakutenAI has 4 listed variants and reaches up to 4k context, while Claude 3 reaches up to 200k context, so compare the specs and pricing tables before choosing a production model.
- Which RakutenAI model should I use?
- If price is the main constraint, use the pricing table first because RakutenAI does not have complete provider pricing in the local data. For the most capable/latest local choice, evaluate RakutenAI 7B with 4k context.
