“日本最强AI”光速塌房，都怪中国DeepSeek太强？

Core Viewpoint - The article discusses the launch of Rakuten AI 3.0, Japan's purportedly strongest AI model, which has been revealed to be a Japanese version of the Chinese open-source model DeepSeek V3, raising concerns about originality and transparency in Japan's AI development [4][8][39]. Group 1: Model Launch and Claims - Rakuten AI 3.0 was launched with claims of being Japan's largest and most powerful AI model, supported by the Japanese Ministry of Economy, Trade and Industry through the GENIAC project [6][12]. - The model boasts an impressive 700 billion parameters, placing it among the top tier of current open-source models [6][12]. - Despite the initial excitement, it was quickly discovered that Rakuten AI 3.0 is essentially a Japanese "shell" version of DeepSeek V3, leading to disappointment among Japanese users [8][11]. Group 2: Community Response and Transparency Issues - The open-source community quickly identified that Rakuten AI 3.0's architecture is based on DeepSeek V3, which was not disclosed during its launch [11][13]. - The lack of acknowledgment of DeepSeek V3 in the model's release raised significant concerns about adherence to open-source principles, particularly regarding the retention of original licenses and attributions [14][25]. - Japanese users expressed frustration, questioning the use of taxpayer money for a model that essentially repackages an existing Chinese product [14][25]. Group 3: Performance Metrics - Rakuten AI 3.0 has shown competitive performance metrics, surpassing GPT-4o in various Japanese language benchmarks, indicating its capabilities in local contexts [16][24]. - The model's cost efficiency is notable, operating at approximately 10% of the cost of leading closed-source models due to its MoE sparse architecture [23][24]. - However, the performance advantages are largely reflective of the underlying DeepSeek V3 architecture, raising questions about the innovation claims made by Rakuten [25][39]. Group 4: Broader Context of Japan's AI Industry - The article highlights a broader trend in Japan's AI industry, where many models are built on existing foreign architectures, indicating a reliance on external technologies rather than homegrown innovation [27][39]. - Japan's IT sector has faced stagnation over the past three decades, struggling to keep pace with global advancements in AI and technology [31][39]. - The situation with Rakuten AI 3.0 exemplifies the challenges faced by Japanese companies in establishing a strong presence in the rapidly evolving AI landscape, often resorting to leveraging existing models rather than developing original solutions [38][39].
