关于人类最后的护城河，我找到了一个答案：故事。 这是读完《温暖的科技》后，我得到的一个感悟。 书中提供了一个关键视角： 人类意识的诞生，其分割线就是我们开始通过故事来理解世界。…
这本 Fall in love with the problem, not the solution 真的神，我愿称之为「创业伟哥」。要经验有经验，要方法论有方法论，要鸡血有鸡血。就是译名有点拉跨。 整本书读完后，我记住了一句话：PMF = 用户留存率。
LLM RL code does not need to be complicated! Here is a minimal implementation of GRPO/PPO on Qwen3, from-scratch in JAX in around 400 core lines of code. The repo is designed to be hackable and prioritize ease-of-understanding for research: github.com/kvfrans/lmpo
Was chatting with a friend at OpenAI — we agreed that good product innovation follows the same principle: breakthroughs happen out of distribution.

Scaling up RL is all the rage right now, I had a chat with a friend about it yesterday. I'm fairly certain RL will continue to yield more intermediate gains, but I also don't expect it to be the full story. RL is basically "hey this happened to go well (/poorly), let me slightly…
So I gave Claude Code a Mac Mini. And it’s called Claudeputer. It runs 24/7 and it’s allowed to do whatever it wants - it’s in complete control of its computer. Watch for a 2min demo.
有训练 Agent 能力的专用框架了！——ART （Agent Reinforcement Trainer） 简单来讲，这个框架可以将 GRPO 集成到你的 python 应用中，比如使用这个训练 Qwen2.5-7B 搜索邮件，或者玩各种游戏。这里使用小模型是因为小模型更适合用于这些零散任务的驱动模型。 想要训练自己的 Agent…
肝了一段时间了，终于要发布了，内测邀请体验中。
很久没聊 RAG 了，随便说点。 RAG 里的分块技术，某种程度上看起来确实显得越来越过时了。 不是说完全抛弃不要，只是分块带来的弊端越来越明显，多高超的技巧都救不回来“信息完整度”的缺失。 当然总有上下文窗口不够的情况，完整的大型文档丢进去，确实吃不下怎么办？ 凉拌。…
5️⃣ A unified MCP server This project builds an MCP server to query and chat with over 200+ data sources using natural language through a unified interface powered by MindsDB and Cursor IDE. GitHub repo → github.com/patchy631/ai-e… Check this workflow 👇
Introducing the next generation: Claude Opus 4 and Claude Sonnet 4. Claude Opus 4 is our most powerful model yet, and the world’s best coding model. Claude Sonnet 4 is a significant upgrade from its predecessor, delivering superior coding and reasoning.
I am afraid to report, RL works.
verl is embracing @PyTorch fsdp2! Better throughput, memory usage, and composability with torch.compile! Please try it out and give us feedbacks: github.com/volcengine/ver…
看到个脑洞大开的项目——VectorVFS 直接往 linux 的 VFS 扩展属性 (xattrs) 里面写临近文件的向量嵌入结果, 来把这些文件的特征向量化存储。这样就能在文件系统中执行一些诸如 "搜索一张包含了苹果但不包含其他水果的图片" 这种高级搜索。 (话说回来我记得由于内核限制，xattrs 应该只能塞64KB?…
今年在一家小几百人startup做芯片，还是有些感慨的 芯片拼到最后就是拼能耗比，这是一级指标，真的是靠堆海量的人力去针对每种workload调试每一点power和performance，人不够就是会有差距，startup对于power和performance的要求要低太多了，只要大差不差就行，能把功能实现出来就是成功…

从 2022 年由财务投资部拆分的 Jinqiu Capital 看到字节范里的坦诚清晰和始终创业，也许公司内部大大小小的组不一定能完全信仰和践行这种极致的风格，但我居然从每一位 Jinqiu 人身上看到了这种特质

#分享 今天在团队分享 MCP，现场用 Cursor AI 写 MCP Server，竟然一次就成功了，今天的工资有 Cursor 的一半，分享一下我的流程： 为了保证 AI 代码直出的成功率，做了一些前置工作： 1. 准备了一个示例项目，就是我之前 mcp-media-server，用 repomix.com 打包成一个单一文件 2.…
Introducing Queue, the simplest podcast app out there. I spent the last few months using it as my daily podcast app and polishing the experience so much that I’m ready to share it with the world. (Sound on!) Here’s how it works 1/4 ⬇️
Just grasped the true significance (not just bc it's submitted by Wenfeng) of this work after reading @SonglinYang4 's explanation. The breakthrough isn't hybrid attention (studied years ago), but the ingenious kernel that delivers real-world speedups for dynamic sparse…
