The fintech company, one of Europe's largest banks, appears to be bringing AI inference in-house rather than relying on external providers. The move is drawing attention among developers discussing cost, control and data-privacy trade-offs of self-hosting frontier Chinese open models.

Tencent has released Hy4, a new open-source artificial intelligence model that the company positions among the world's leading open-source AI systems. The launch adds to the growing competition in open-weight AI, where Chinese firms have been rapidly releasing models that rival Western offerings. Details about Hy4's performance benchmarks and licensing terms have not yet been widely reported.

Physicists have claimed that anomalies in particle collision data from the Large Hadron Collider could be explained by the existence of a fifth dimension. The proposal suggests unusual measurements at CERN's collider might be evidence of physics beyond the Standard Model, though the idea remains speculative and would require further experimental confirmation.

A commentary piece titled 'Open source is not enough' argues that releasing code under an open license alone does not guarantee sustainable software, adoption, or community maintenance. The argument has drawn heavy engagement among developers and software communities, sparking debate over what else open projects need, such as funding, governance, documentation, and long-term maintainers.

Scenario Labs has published a set of skills for AI agents that generate production-ready images, video, audio, and 3D content. The tools let agents choose the right model, estimate costs before spending, and keep characters and brands consistent via the Scenario MCP. Separate expert teams drive Blender, Maya, ZBrush, Unreal, and Unity workflows.

Orders for the iPhone 18 Pro are now officially open, and tech outlets are running buyer's guides covering pricing, configurations, delivery dates and whether an upgrade is worthwhile. Apple's latest Pro model is expected to be one of the most discussed smartphone launches of the season, with early coverage focusing on what changes it brings over the previous generation.
