Dongcha Beating AI News Flash: The People's Bank of China (PBOC) will issue the "Sci-Tech Innovation Future (Artificial Intelligence)" gold and silver commemorative coin set, consisting of 3 pieces: 1 gold coin and 2 silver coins, all legal tender. The 5-gram gold coin is 18mm square, with designs including a chip, brain-shaped circuit, and 0/1 elements on its reverse side. Each of the two 15-gram silver coins features distinct designs: one with a face, circuit, and spiral dot matrix; the other with a key and AI symbol. The gold coin has a face value of 80 yuan, with a maximum mintage of 10,000 pieces; each silver coin carries a face value of 5 yuan, with a maximum mintage of 20,000 pieces. It should be noted that the face value here is not the selling price. The face value of precious metal commemorative coins mainly serves to indicate their legal tender status, while the actual selling price is determined by factors such as gold/silver raw material costs and production expenses. In March this year, when soliciting coin design drafts, the organizer explicitly allowed designers to use AI tools for assistance, but prohibited submitting AI-generated content directly. The three coins are themed respectively on: basic research in artificial intelligence, "technology for good", and the application of "AI +" across various industries.

Beating AI Express News: Tencent’s Hunyuan Hy4 preview not only scales up the model size but also overhauls its underlying architecture. The previous Hy3 generation used traditional full attention, while Hy4 adopts Gated DSA, the gated version of DeepSeek Sparse Attention. When processing extremely long texts, the model no longer recalculates all previous content; instead, it first selects the most relevant parts for focused processing. Hy4 also adds IndexCache to DSA. Originally, each layer of the model had to re-judge which content is most important, but now some layers can directly reuse earlier selected results, cutting down on significant redundant computation. Tencent explicitly stated that this design is inspired by DeepSeek and GLM. Another change is the residual structure: traditional Transformers can be roughly viewed as having only one information backbone, while Hy4 uses iHC to expand this to four backbones, enabling the model to retain more information simultaneously in deep networks. The number of MoE (Mixture of Experts) experts has also increased from 192 in Hy3 to 256 routing experts plus 1 shared expert. Each token selects 8 routing experts and always passes through the shared expert.
