自 Golden Gate Claude 以来，作者一直对 LLM "引导"技术（在推理过程中直接操控模型激活值）充满兴趣。随着足够强大的本地模型 DeepSeek-V4-Flash 和配套工具 DwarfStar 4 的出现，引导技术对许多工程师而言变得可行。文章探讨了引导的基本原理（通过对比激活值提取"简洁回答"等概念向量并放大）、其吸引力（绕过繁琐训练直接"拧动智能旋钮"）、以及为何尚未被广泛采用——大型AI实验室可通过训练直接操控模型，而普通API用户无法访问模型权重。作者认为多数引导效果可通过提示词更高效实现，但开源社区在这方面的探索才刚开始，未来六个月可能带来惊喜。
Jimmy Wales announced that Wikipedia was live at wikipedia.com on January 15, 2001. The site was intended to be a "really quite snazzy" wiki complement to the Nupedia project, offering a more collaborative and less formal environment for building an encyclopedia.
Realta Fusion has achieved a milestone by generating electricity directly from a fusion reaction, reportedly a first. The breakthrough marks a significant step toward practical fusion energy, potentially offering a clean and nearly limitless power source.
OpenAI has announced Daybreak, a new initiative focused on advancing AI safety and alignment research to ensure artificial general intelligence benefits humanity.
SpaceX has announced plans to launch approximately one million satellites to create space-based data centres, according to the European Southern Observatory (ESO). The massive satellite constellation would significantly increase the number of objects in orbit, raising concerns about light pollution and interference with astronomical observations.
Max Weinbach says he had early access to OpenAI's new model GPT-5.6 Sol, calling it his favorite model by far. He highlights that it never gives up and will keep reasoning until it's done. OpenAI announced that GPT-5.6 Sol, along with Terra and Luna, will launch publicly on Thursday, with preview access expanding globally now.
