What a ridiculous decision from #NeurIPS! Some of the companies affected have sponsored you for years! Blows my mind! #AI #MachineLearning
















很遗憾 最近才晓得这个AI+Web3项目的创办人自杀了 他们的项目官推也已经停止更新 创业的压力很大 要跟社区、团队、投资人有交代 还有自己给自己的压力 名校毕业又怎么样? 拿到融资又怎么样? 发币上所又怎么样? 挽回不了一条活生生的人命


Here is an xAI story. When I was first hired (low level) by xAI, I was extremely excited. I greatly admired Elon and what Grok could be. I have a pretty cool AI following here on X. Some big names see my stuff, including Elon himself (at the time). Lex, Beff, Andreessen, Aravind, many others. During the interview and onboarding for xAI, they made a *big deal* about wanting people who "take initiative" and think outside the box. Ok... So, some of the biggest names in tech follow me on X. I decided to ask for ideas and feedback on how Grok (then still early at version 2) could be improved. I asked my followers on X for the best "how can we make Grok awesome?" ideas, and was going to collect them (organized by Grok himself) into a big report for my boss(es) and ultimately, Elon. (xAI makes a big deal about how it's a "flat structure" also. You're supposed to be empowered to act on good ideas.) Well, my post got way more attention than I expected - great! Ideas to improve Grok poured in! I built a script to collect and sort all these great ideas to make xAI's core product better. John Carmack (personal friend of Elon, creator of Doom, id software, legend) retweeted it. Carmack has 1M followers. There were so many great ideas on how to improve Grok! I was collecting them and excited. Until....... I woke up the next day to a threatening email from my main supervisor* at xAI, telling me I had messed up, that I was NEVER to ask for ideas to improve Grok ever again, that it wasn't my job (I thought our job was to improve Grok.) They suspended my account on X. They never explained why. It was obviously related to my post about improving Grok. I was told to delete those posts which had gone viral. I had to delete all the hundreds (thousands?) of genuinely good ideas for improving Grok that had poured in by users on X, because it stepped on someone's toes. It made me confused and sad. Incidents like this happened often, where xAI employees would come in full of excitement and enthusiasm, and would have it stomped out by managers who hated ideas. They filled xAI with middle managers and busybodies. It was one of the most DEI and corporate-y places I've ever worked. I came in wanting Elon and xAI to win and left just sad. *That manager is gone, for what it's worth. Everyone I knew at xAI is gone.




🚀 We are excited to open-source HY3D-Bench, a unified, high-quality dataset for 3D asset generation. Addressing data scarcity and inconsistent evaluation, we provide a massive, training-ready library. Core Highlights: -252k+ High-fidelity 3D objects (rigorously filtered) -240k+ Structured part-level decomposed data for fine-grained control -125k AIGC-synthesized assets for class balance -Hunyuan3D-2.1-Small: A lightweight, SOTA baseline for easy reproduction HY3D-Bench simplifies access to robust data resources, aiming to catalyze innovation across 3D perception, robotics, and digital content creation. 🔗 GitHub: github.com/Tencent-Hunyua… 🤗 Hugging Face: huggingface.co/tencent/HY3D-B… 📂 Dataset: huggingface.co/datasets/tence… 📄 Paper: arxiv.org/pdf/2602.03907
