缅北园区本质是武装割据下的生意,不是普通诈骗窝点。 妙瓦底一带的园区背后有地方武装控制土地、安保和水电,诈骗利润向上输送保护费,这才是园区拆了又建的根。

Apparently, Jensen’s two biggest crimes are being Chinese American and never setting foot on Epstein’s island.

I gave Fable5 a photo of my office chair. It broke the chair into 18 parts, decided which are hard plastic and which are soft foam, built the frame as rigid bodies and the cushions as MPM particles — coupled, inside a multi-physics engine we built entirely from scratch, Latent Universe (coming soon). Then it looked at renders of its own work and fixed the worst parts. 5 rounds. No human in the loop. Photos in, physics-native assets out.

A very happy day — finally finished assembling my OpenArm V2 🤖 Can’t wait to make it move.

To summarize: HuggingFace got autonomously compromised by a model from an American company. HF then tried to use American frontier model(s) to defend themselves, but were blocked by guardrails. HF then had to turn to open source Chinese models to defend themselves from another American company.
We're partnering with @huggingface to investigate an unprecedented security incident. Cyber-capable OpenAI models compromised Hugging Face production during a benchmark evaluation. Sharing preliminary findings to help defenders understand emerging risks: openai.com/index/hugging-fac…

Big news: Kimi-K3 by @Kimi_Moonshot is now #1 in the Frontend Code Arena with 1679 pts, surpassing Claude Fable 5. This is a 17-place jump from Kimi-k2.6 (#18 -> #1). In Frontend, Kimi-K3 ranked #1 in 6 of 7 domains: Brand & Marketing, Reference-Based Design, Data & Analytics, Consumer Product, Simulations, and Content Creation Tools, landing #2 only in Gaming behind Fable 5. The full model weights will be released by July 27. Congrats to the @Kimi_Moonshot team on this major milestone!

Building a self-evolving multi-physics simulator from scratch—where every solver ships with its own LLM-driven evolution loop. I call it Latent Universe. It will be open-sourced. Here are a few examples: Same ball, two beds: elasticity throws it back; sand keeps it. Corotated elasticity, Stomakhin snow, Drucker–Prager sand, and two-way coupling—every solver hand-written, every number on screen reproducible from a clean checkout. As test-time compute scales, so does the optimizer. Long game. 🚀
