The diverging path of China's two leading AI players shows where the country's artificial intelligence industry is headed. DeepSeek and ByteDance, the two leaders of China's AI industry, are adopting vastly different strategies. On Monday, DeepSeek released DeepSeek V3.2, another open-weight model that anyone can tinker with. The startup says it performs on par with the latest models from OpenAI and Google, and it even beats them on some key mathematics benchmarks. That same day, ByteDance, whose dominance in AI applications we covered previously, introduced ways for people to use its chatbot, Doubao.

The Chinese video game giant Tencent is now building some of the world's best 3D AI models. This could have implications far outside game design. The video game Valorant, a fast-paced team-based shooter, has recently become a testing ground for a promising new direction in artificial intelligence research. The game's developers at Riot Games (a Tencent subsidiary) are using 3D-native AI models to prototype new characters, scenes, and storylines, according to a researcher familiar with the company's efforts who spoke on the condition of anonymity. While many AI models can generate text, images, and video, Tencent's Hunyuan (混元 or "first mix") family of models can dream up 3D objects and interactive scenes.

We're a week into the school summer holidays here in England, and I wonder how many parents who started out determined to keep their children completely away from screens are now beginning to feel the strain. When my sons were much younger, I often had these idyllic images in my head of day trips to the seaside, back garden treasure hunts, paddling in the river, visiting relatives … an endless series of character forming experiences which I imagined in grainy Kodachrome colours. Then I'd be faced with the reality of having a job, and also the, let's say, limited attention span of my sons. Sheepishly, we'd end up allowing some Fortnite time to catch our breath. There is so much pressure and guilt around children and gaming, especially during long school breaks, and I think we need to seriously redress our outlook as a society.

Ubisoft is continuing its efforts to course-correct after several challenging years. Today, the video game company announced that it will launch a subsidiary centered around three of its most familiar franchises: Assassin's Creed, Far Cry and Tom Clancy's Rainbow Six. The as-yet-unnamed subsidiary will fold in the teams working on those three series, including Ubisoft studios in Montréal, Quebec, Sherbrooke, Saguenay, Barcelona and Sofia. This new business will receive an investment of 1.16 billion (roughly 1.25 billion) from its longstanding partner Tencent, granting the conglomerate a minority ownership stake. Following the transaction, Ubisoft will narrow focus to its other franchises, such as The Division and Tom Clancy's Ghost Recon.

Tencent is one of China's largest technology companies Chinese tech giant Tencent doesn't seem to be affected by US export bans of computer chips that are crucial to the development of artificial intelligence systems – but even if such bans were more stringent, they may not be able to slow the country's AI advancement, US research shows. Ritwik Gupta and his colleagues at the University of California, Berkeley, have analysed publications released by researchers at Tencent about the firm's latest models, including its Hunyuan AI models.

U.S. export controls on semiconductors are widely known to be permeable, with the People's Republic of China (PRC) steadily creating state-of-the-art artificial intelligence (AI) models with exfiltrated chips. This paper presents the first concrete, public evidence of how leading PRC AI labs evade and circumvent U.S. export controls. We examine how Chinese companies, notably Tencent, are not only using chips that are restricted under U.S. export controls but are also finding ways to circumvent these regulations by using software and modeling techniques that maximize less capable hardware. Specifically, we argue that Tencent's ability to power its Hunyuan-Large model with non-export controlled NVIDIA H20s exemplifies broader gains in efficiency in machine learning that have eroded the moat that the United States initially built via its existing export controls. Finally, we examine the implications of this finding for the future of the United States' export control strategy.

Welcome back to our weekly gaming news roundup. As the year comes to a close, we're looking back on 12 months of massive change for the video game industry, driven by acquisitions, layoffs and unionization. You can read my story on consolidation for more on gaming's tough year. Baldur's Gate 3 is officially the Game of the Year and after months as a PlayStation console exclusive, it's finally available on Xbox. However, if you're waiting for it to become available on Game Pass, stop.
