论文链接：https://arxiv.org/abs/2506.20512 代码仓库：https://github.com/GAIR-NLP/OctoThinker 近期，一份来自上海创智学院、上海交通大学的前沿研究论文吸引了人工智能领域的广泛关注。该论文深入探讨了不同基础语言模型家族（如 Llama 和 Qwen）在 强化学习（RL）训练中迥异表现的背后原因，并提出创新性的中期训练（mid-training）策略，成功地将 Llama 模型改造成高度适配强化学习的推理基础模型，显 著缩小了其与天生擅长 RL 扩展的 Qwen 模型之间的性能差距，为下一代 reasoning 能力 AI 系统的开发提供了关键的科学基础和技术路径。 论文发布后在社交媒体引发广泛关注，Meta AI 研究科学家、即将赴 UMass Amherst 任助理教授的 Wenting Zhao 率先盛赞："Truly impressed by how an academic lab just figured out a lot of mysteries in mid-training to close the RL gap betwee ...

[Music] As I gasped for air, barely able to move after my 10k run, I thought maybe I'm not built for this. But then I realized pain was giving me a choice. I could kit or I could continue.What if I told you that pain is not our enemy but our greatest teacher. The very thing we spend our lives avoiding could be the thing to unlocking our achievement. We all experience pain physically, emotionally, mentally.But the real question is what if we chose to embrace pain. Could it be the gateway to something greater ...

The kind of key headline from from the React piece is that Tester's vehicle cost is about one seventh of waymo's. Why were you so focused on that, Steve. Well, I think I think that the critical piece in getting it on a commercial basis on a mass scale basis and also the payback is also important.If you can produce the cars at a fraction of the price. You know, you can get more of these vehicles out on the road. And also, you know, whoever is running them can actually make their money back much sooner.The is ...
