Today, we released Lyra 2.0, a framework for generating persistent, explorable 3D worlds at scale, from NVIDIA Research. Generating large-scale, complex environments is difficult for AI models. Current models often “forget” what spaces look like and lose track of movement over time, causing objects to shift, blur, or appear inconsistent. This prevents them from creating the reliable 3D environments required for downstream simulations. Lyra 2.0 solves these issues by: ✅ Maintaining per-frame 3D geometry to retrieve past frames and establish spatial correspondences ✅ Using self-augmented training to correct its own temporal drifting. Lyra 2.0 turns an image into a 3D world you can walk through, look back, and drop a robot into for real-time rendering, simulation, and immersive applications. ➡️ Learn more: https://t.co/ROR7miJeCU 📄 Read the paper: https://t.co/1osU9EGjGD

Banger paper from NVIDIA. Agentic reasoning needs models that are not just capable, but efficient at long-context inference. The agent model layer is moving toward open, long-context, high-throughput architectures. This paper introduces Nemotron 3 Super, an open 120B parameter model with 12B active parameters, built as a hybrid Mamba-Attention Mixture-of-Experts architecture. The headline numbers are strong: up to 1M context length, comparable accuracy on common benchmarks, and up to 2.2x higher throughput than GPT-OSS-120B and 7.5x higher throughput than Qwen3.5-122B. The model combines several efficiency bets, including NVFP4 pretraining, LatentMoE for accuracy per FLOP and per parameter, and MTP layers for native speculative decoding. It is trained on 25 trillion tokens, then post-trained with supervised fine-tuning and RL. Paper: https://t.co/VcqUPjylzF Learn to build effective AI agents in our academy: https://t.co/LRnpZN7L4c

New course: Spec-Driven Development with Coding Agents, built in partnership with @jetbrains, and taught by @paulweveritt. Vibe coding is fast, but often produces code that doesn't match what you asked for. This short course teaches you spec-driven development: write a detailed spec defining what to build, and work with your coding agent to implement it. Many of the best developers already build this way. A spec lets you control large code changes with a few words, preserve context across agent sessions, and stay in control as your project grows in complexity. Skills you'll gain: - Write a detailed specification to define your mission, tech stack, and roadmap, giving your agent the context it needs from the start - Plan, implement, and validate features in iterative loops using a spec as your agent's guide - Apply the same repeatable workflow to both new and legacy codebases - Package your workflow into a portable agent skill that works across agents and IDEs Join and write specs that keep your coding agent on track! https://t.co/hI4GwuvhtN

A new and troubling risk is emerging around AI. An attacker targeting Sam Altman reportedly had a broader list of AI executives, raising concerns that individuals in the industry could become targets. It signals a shift. As AI’s influence grows, so do the stakes, and the risks are no longer just digital. https://t.co/50J0jk5tFz @fortunemagazine @marcoquiroz10

This AI car drove through 506 cities, a Tokyo typhoon, and Arctic darkness without a single external map. @wayve_ai is giving Waymo and Tesla a run for their money, and most people haven't noticed yet. @l2k sits down with CEO @alexgkendall, who breaks down how they got here and where it's going next. In his words: "taking it from expensive retrofit vehicles to mass-market vehicles that you can buy or manufacture." The old self-driving playbook is dead. The question is who writes the new one. Is your next car going to drive itself before you even think to ask for it?

Robots are maturing. AI models are advancing. Deployments are rarely scaling. Today, deploying a robot still means stitching together systems that were never designed to work together. For every robot. Every time. The industry needs a unified intelligence infrastructure that any robot, any model and any workflow can plug into. We call this an intelligence grid. Infrastructure that makes intelligence composable, deployable, and continuously adapting. Every connected robot evolves as the platform advances. More on what we're building: https://t.co/AMpxxFmtuc

BREAKING: DHS confirms to @FoxNews that Olaolukitan Adon Abel, the suspect arrested for a seemingly random murder spree in DeKalb County, GA that left two women dead and a homeless man shot, is a national of the United Kingdom who was naturalized into a US citizen during the Biden administration in 2022. DHS confirms to FOX that one of the victims, 40-year-old Lauren Bullis, was a DHS employee who worked in the DHS Office of the Inspector General. She was found stabbed and shot to death while walking her dog. Abel faces two counts of murder, aggravated assault, and weapons charges after police say he carried out an early morning shooting spree in three separate locations in DeKalb County, GA on Monday, shooting and killing a woman in front of a Checkers, shooting and stabbing Lauren Bullis to death while she was walking her dog, and shooting a homeless man several times in front of a shopping center. Motive is unknown. DHS confirms that Abel had a lengthy rap sheet prior to this incident, including prior convictions for sexual battery, battery against a police officer, and assault with a deadly weapon.

Grok just hit its highest monthly traffic EVER: over 326 MILLION visits in March alone That’s a massive 61% jump YoY and up 9.3% just since February People love Grok because it's the only AI they can trust with the answers and ask anything without hitting the policy walls unlike other AIs

It took me a few hours yesterday, but I got access to the case files for Olaolukitan Adon Abel previous se*ual battery case from Savannah GA that caused him to be BANISHED from the ENTIRE CITY. I'll drop the files below, but here's the story: >Abel assaulted 4 different women in the span of a few hours >4 victims, 4 counts of se*ual battery, in Chatham County, April 2025. >When police tried to arrest him, he resisted. >They added an obstruction charge on top of everything else >That obstruction charge vanished before trial >Prosecutors dropped it entirely. No explanation given. >His attorney, B. Foster, got all 4 se*ual battery counts handled under Georgia's First Offender Act >Meaning if he completed probation, the whole thing would essentially disappear from his record. >The judge sentenced him to 48 months, then suspended most of it. >He actually served 120 days in prison TOTAL >Thirty days per victim >He paid $0 in fines >Zero in restitution to any of the 4 women >The court did order a psychose*ual evaluation and required he follow whatever treatment came from it >They mandated mental health counseling >They banned him from the entire city of Savannah for four years >They explicitly prohibited him from possessing any firearm >He signed the probation agreement on June 7, 2025 >7 months later, he got a gun and m*rdered 2 women, including Lauren Bullis You are not angry enough.

mathematician Terence Tao on the gpt-5.4 pro solving Erdős problem #1196: "the AI-generated paper may have made a meaningful contribution by revealing a deeper mathematical connection that earlier work had not clearly made explicit, which value beyond solving this particular erdős problem"

A couple of people asked me how I did it, so here's the answer: Asking in ChatGPT (not codex, that's a different gpt-5.4) the GPT-5.4 Pro Extended Thinking to solve it. Now, here's a caveat: if you just put "Solve X" and X is an open problem that is easily searchable to be open (e.g. Erdos problem), you get nothing really, just a literature search. So to really force an LLM to think hard about it there are 2 methods: 1. Add "Don't search the internet, this is a test of your reasoning capabilities". Yeah, really. Add after that "Solve X" and it will give it a shot. The problem with that is it often tries to solve problems without searching for any kind of research, so it only works on simpler problems. 2. Add guidance "Solve X with method Y". Now this is really good is you have mathematical background, because you can find some good Y (assuming it's your domain), but you can also pick Y at random from doing a literature search first. now for the actual problem I solve here, I did 2., but with a caveat of running agents before hand. I have the full repo of Agentic Erdos: https://t.co/xegnXal7UT where I've run AI agents over ALL Erdos problems, basically doing basic compute, some arguments, some literature. So when I go to ChatGPT I can use that as a very specific prompt.

Small models are cheap to run, but expensive to adapt. The hard part is not only fine-tuning. It is the surrounding loop that involves collecting data, diagnosing failures, building evals, avoiding regressions, choosing curricula, and deciding when an update is safe. This new paper introduces Pioneer Agent, a closed-loop system for continual improvement of small language models in production. In cold-start mode, the agent starts from a natural-language task description, acquires data, builds evals, and iteratively trains models. In production mode, it uses labeled failures to diagnose error patterns, synthesize targeted data, and retrain under explicit regression constraints. The results are strong: gains of 1.6 to 83.8 points across eight cold-start benchmarks, no regressions across seven AdaptFT-Bench scenarios, intent classification from 84.9% to 99.3%, and Entity F1 from 0.345 to 0.810.

Long-horizon AI research agents are mostly a state-management problem. It is not enough for an agent to reason well in the next turn. ML research requires task setup, implementation, experiments, debugging, and evidence tracking over hours or days. This new paper introduces AiScientist, a system for autonomous long-horizon engineering for ML research. The key idea is to keep control thin and state thick. A top-level orchestrator manages stage-level progress, while specialized agents repeatedly ground themselves in durable workspace artifacts: analyses, plans, code, logs, and experimental evidence. That "File-as-Bus" design matters. AiScientist improves PaperBench by 10.54 points over the best matched baseline and reaches 81.82 Any Medal% on MLE-Bench Lite. Removing File-as-Bus drops PaperBench by 6.41 points and MLE-Bench Lite by 31.82 points. Why does it matter? Autonomous research agents need durable project memory, not just longer chats.
