Rakuten Group launched its Japan-focused AI model, Rakuten AI 3.0, amid rising interest in AI and crypto news. The model claims to outperform GPT-4o on Japanese benchmarks, using open-source data and internal training. However, users noted that the Hugging Face configuration file lists 'deepseek_v3' as the model type, sparking debate over its underlying architecture. Some also reported a China-leaning bias in responses, raising questions about Japan’s involvement in its development. Inflation data trends remain a separate but closely monitored factor in the broader tech and crypto markets.

PANews, March 17: Rakuten Group announced the launch of Rakuten AI 3.0, a Japanese-language specialized large model. The company claims that the model outperforms models such as GPT-4o on multiple Japanese-language benchmarks, including Japanese culture and history, and instruction following. It was developed by building upon open-source community models and incorporating proprietary bilingual data. However, users on X discovered that the config.json file on the project’s Hugging Face page contains entries such as "model_type": "deepseek_v3." Additionally, when answering related questions, the model’s stated positions appear significantly more aligned with China than with Japan. This has sparked online discussions about whether the model is based on DeepSeek and how much of its technology was independently developed in Japan.
