This is today’s edition of The Download, our weekday newsletter that provides a daily dose of what’s going on in the world of technology. Open models have real benefits. Do they outweigh the risks? Anthropic recently released a report arguing that a powerful new model released by the Chinese company Z.ai, poses a major cyberattack risk. Its core concern was that it is freely available for anyone to download and modify. The warning was the latest flashpoint in a debate over whether frontier AI models should be open or kept behind the doors of frontier labs. Safety advocates warn that open models can be misused by bad actors, while supporters argue they could prevent a handful of companies from controlling this powerful technology. Here’s why the debate over open AI is more complicated than it seems. —Grace Huckins

这是今天的《下载》栏目，我们平日的通讯为您提供每日科技动态。开源模型确实有其益处，但它们带来的风险是否超过了收益？Anthropic 最近发布了一份报告，指出中国公司 Z.ai 发布的一款强大新模型构成了重大的网络攻击风险。其核心担忧在于，任何人都可以自由下载并修改该模型。这一警告是关于前沿人工智能模型究竟应该开源，还是应保留在实验室内部这一争论的最新焦点。安全倡导者警告称，开源模型可能被不法分子滥用，而支持者则认为，开源可以防止少数几家公司垄断这项强大的技术。这就是为什么关于开源人工智能的争论比看起来要复杂得多。——Grace Huckins

Fervo Energy wants to expand geothermal power beyond the handful of places where it has traditionally been practical. The company uses horizontal drilling and hydraulic fracturing to open pathways through underground rock, potentially making geothermal development possible in far more places. Now, Fervo is betting that AI’s power boom will help scale up enhanced geothermal energy. With a $2.2 billion public offering and an expanded agreement with Google, it plans to build larger plants and drive down costs. But can its approach work beyond Utah and Nevada?
