Did you know? When snails hatch, they eat the shells of their eggs. This gives them needed calcium for their own shells.

The Visitors (Made with Veo 3). Humans react to alien visitors. This mini project was completed in 8 hours, from start to finish, by one person. The tools I used are listed at the end of the video.
🚨 China: Massive explosion at Shandong Youdao Chemical plant in Gaomi city. At least 5 dead, 19 injured, 6 missing. The factory manufactured Chlorpyrifos, neurotoxic organophosphate insecticide that acts as a nerve agent.
😈 BEWARE: Claude 4 + GitHub MCP will leak your private GitHub repositories, no questions asked. We discovered a new attack on agents using GitHub’s official MCP server, which can be exploited by attackers to access your private repositories. creds to @marco_milanta (1/n) 👇
Pythagorian triples in complex number space (a+ib)^2 + (c+id)^2 = (e+if)^2.
This perfectly articulates why "model alignment" is the wrong way to think about AI safety. Safety is not a property of models, it's a property of systems that use models. Asking whether a model is safe is like asking whether a computer chip is safe.
12/ Despite wartime constraints, Ukraine has rapidly ramped up domestic weapons production. Casper of the 14th Separate UAV Regiment, says 80–90% of the drones his unit now uses are made in Ukraine, compared to near-total reliance on foreign models in the early years of the war.
I know we aren’t supposed to interrupt the group chat discourse with woke nonsense like the habitability of our planet, but possibly the most intense heat wave on record is unfolding from Sub-Saharan Africa to East Asia and it’s getting zero attention.
ABSOLUTE INSANITY Unbelievable hot nights in CENTRAL ASIA Thousands of records of April hottest nights brutalized with the hugest margins ever seen in world climatic history (locally 10C+ above monthly records !) Anything happened anywhere is nothing to what it's happening now
Game over. Grok won. If you’re an investor in OpenAI, you can report the tax loss to your accountant this year.

A new paper demonstrates that LLMs could "think" in latent space, effectively decoupling internal reasoning from visible context tokens. This breakthrough suggests that even smaller models can achieve remarkable performance without relying on extensive context windows.
Given a pretrained model, spline theory tells you how to alter its curvature by changing a single interpretable parameter! Reducing the model's curvature always significantly improves its downstream task performances/robustness. Also work on Transformers! arxiv.org/abs/2502.07783
The Kalman Filter was once a core topic in EECS curricula. Given its relevance to ML, RL, Ctrl/Robotics, I'm surprised that most researchers don't know much about it - and up rediscovering it. Kalman Filter seems messy & complicated, but the intuition behind it is invaluable 1/4
Live from Paris, at the #ParisAISummit . I gave the opening keynote about AI’s past, present, future and opportunities. “75 years ago, Alan Turing dared humanity to imagine ‘thinking machines’. But perhaps that vision is too narrow and inward-looking. As AI today is poised to…
🚨 Studies are starting to show what many of us feared: AI use might lead to overreliance and human disempowerment. Below is the SHOCKING conclusion of this particular study [download for future reference]: "1. We surveyed 319 knowledge workers who use GenAI tools (e.g.,…
Hyperparameter of the day! Have you adjusted your adam_beta2 lately? Ever? You might want to, especially if you're working in RL. Beta2 usually defaults to 0.999 - what does that mean? Interpret it it by computing 1/(1-beta2), so with beta2=0.999 this comes out to 1000,…
Large Memory Models for Long-Context Reasoning This paper focuses on improving long-context reasoning with explicit memory mechanisms. It presents LM2, a Transformer-based architecture equipped with a dedicated memory module to enhance long-context reasoning, multi-hop…
