Nvidia’s Nemotron 3 Ultra. A 550B MoE frontier-intelligence open model built for long-running agents. It delivers 5x faster inference and lowers the cost of complex agentic tasks by up to 30% versus other open frontier models.

Generative Recursive Reasoning GRAM (Generative Recursive reAsoning Models) turns recursion itself into a stochastic latent trajectory. Multiple hypotheses, alternative solution strategies, and inference-time scaling not just by depth, but by width — parallel trajectory sampling.

Should a government without a majority of the vote be able to doom entire species to extinction? Proportional representation ensures environmental protections are built on broad majority consensus, not something to be ripped up when they become inconvenient.
A screenshot of a social media post by Emma McIntosh (@EmmaMci). The text reads: "From @althiaraj: The federal government’s proposal to legally allow projects to go ahead even if they result in an entire species going extinct is directed at projects that would affect endangered orcas in BC." Below the text is a partial link to a Toronto Star article.

Perhaps his plan is to steal their model and usage data? Until recently I would trust Anthropic not to train on enterprise data. But not with X into the picture.

High speed rail is a classic example of first-past-the-post policy whiplash. Governments elected with 40% or less furiously undo previous projects, so nothing gets built. Proportional representation incentivises broad consensus and stable, long term planning.
Screenshot of a Toronto Star tweet showing the outlet name and handle @TorontoStar with a verified checkmark. The headline reads: “Pierre Poilievre says he would cancel high-speed rail line between Toronto and Quebec City,” followed by a shortened link.

It definitely looks like a grift between Putin and Trump. Trump is most likely being blackmailed. Why else could this war instantly be improving Russia’s economic fortunes, while continuing to damage the economies of the rest of the world. There are so many other options for Trump and he chose this.

LLMs are largely memory bound! Tokenizers can eat >30% of on‑device memory for small (<1B) models, because we reuse the huge vocabularies from big models. Our method lets you distill large models into small ones with much smaller vocabulary, reducing overall memory footprint.

They propose a new paradigm called Drifting Models, which evolve the pushforward distribution during training and naturally admit one-step inference. We introduce a drifting field that governs the sample movement and achieves equilibrium when the distributions match.
