NVIDIA built a 30B model for the boring half of agent work News
NVIDIA released Nemotron 3.5 Lightning, a 30-billion-parameter mixture-of-experts model that activates only 3 billion parameters per token and is aimed at the tool calls and validation steps that consume most of a long-running agent's time.
NVIDIA lines up six financiers to mobilize 500 billion dollars News
NVIDIA announced agreements with Apollo, BlackRock, Blackstone, Brookfield, Goldman Sachs, and KKR to build independent financing platforms intended to mobilize more than 500 billion dollars of third-party capital for AI compute infrastructure.
NVIDIA's Open Full-Duplex Voice Model Wants an 80GB GPU News
NVIDIA released an 11-billion-parameter speech model that listens and speaks at the same time and calls tools mid-conversation, and its own documentation requires a GPU with at least 80 GB of memory and lists more than a dozen failure modes.
The "2x GB200 bandwidth" Chinese chip claim is a 2027 projection, and the arithmetic gives 1.67x News
A widely shared claim that a Chinese accelerator delivers twice the memory bandwidth of NVIDIA's GB200 traces to a roadmap part expected in early 2027, compared 64-at-a-time against a full NVIDIA rack, and the published numbers work out to 1.67 times at rack level while the single chip lands below a shipping GB200.
NVIDIA shipped a drop-in kernel that nearly halves video generation time News
NVIDIA released code on July 28 for Sol-Attn, an attention kernel that decides which parts of a long video to compute exactly while approximating the rest inside a single pass, reporting up to 2.1 times faster video generation with no retraining and no weight changes.
NVIDIA launches an open AI security alliance with 41 partners, and OpenAI is not on the list News
NVIDIA announced the Open Secure AI Alliance with 41 inaugural partners including Microsoft, the Linux Foundation, Hugging Face and CrowdStrike, built around the claim that closed APIs blocked forensic work during the Hugging Face breach while an open model did it.
NVIDIA invests in Safe Superintelligence, promising an order-of-magnitude compute jump News
NVIDIA and Ilya Sutskever's Safe Superintelligence announced a long-term strategic partnership including an NVIDIA equity investment, which SSI says will expand its available compute by an order of magnitude.
NVIDIA Is Reportedly in Talks to Guarantee $250 Billion of OpenAI's Ohio Buildout News
The Wall Street Journal reports NVIDIA is discussing a roughly $250 billion credit guarantee for the lease and construction debt behind OpenAI's planned 10-gigawatt Ohio campus, a backstop that reportedly excludes the chips themselves.
The open-weights industry letter grew from 25 names to 35 - and OpenAI is on it News
A cross-industry statement titled Open Weights and American AI Leadership now lists 35 signatories on its live Microsoft-hosted page, including OpenAI, Nous Research, GitHub and Cisco, contradicting the widely shared claim that OpenAI declined to sign.
Nvidia's 'Puzzle' pipeline shrinks a 120B model to 75B and roughly doubles serving throughput News
Nvidia's Nemotron-3-Puzzle compresses a 120-billion-parameter model down to 75 billion using a multi-stage pipeline of pruning, distillation, and quantization -- roughly doubling throughput on a B200 node and lifting single-H100 concurrency at long context from one request to eight.
Analysts warn Nvidia's AI boom is being propped up by a circular financing loop with the 'neoclouds' News
An IO Fund analysis details how Nvidia invests billions into GPU-rental 'neoclouds' like CoreWeave that then use that capital to buy Nvidia chips -- a self-reinforcing loop that includes a $6.3 billion Nvidia backstop obligating it to buy CoreWeave's unsold GPU capacity through 2032.
Nvidia is now backstopping the sales of its own chips News
Nvidia formalized a financing program that guarantees a revenue floor for cloud firms buying its GPUs in exchange for a cut of their sales - a move analysts say could help drive AI debt past $7 trillion by 2029.
NVIDIA Starts Taking a Share of Its Cloud Partners' Revenue, Not Just Selling Them Chips News
NVIDIA announced a new arrangement where it earns a share of the cloud revenue its partners generate from NVIDIA-supported data center capacity, on top of its usual chip sales, with first partners Sharon AI and Firmus building campuses totaling hundreds of thousands of GPUs.
NVIDIA's new method stops AI dream-worlds from breaking the laws of physics News
PhysisForcing trains video-generating world models to keep objects solid and interactions believable, raising how often a robot's imagined plan actually works.
NVIDIA's warm-water fix for AI's thirsty data centers News
A new NVIDIA cooling design claims to use almost no water inside the data center, though critics say that's only part of AI's water bill.
NVIDIA shrinks video generation down to real time News
A new NVIDIA recipe distills slow video-generating AI into a fast version that can stream frames live and react to your actions.
Sol-Attn (Sol-Engine) Tool
NVIDIA's drop-in sparse attention kernel for long-video diffusion transformers, released July 28 for HunyuanVideo-13B and Wan2.1-T2V-14B. Screens compressed key/value blocks inside a single online-softmax pass, so exact attention goes where it matters and skipped blocks get an approximate correction. Training-free, no weight changes, reported up to 2.1x for generation and 2.3x for editing. The repo marks end-to-end re-benchmarks for the two integrated pipelines as pending.
Nemotron-3-Puzzle-75B Tool
Nvidia's compressed 75B open model (from a 120B parent) with roughly double the serving throughput and 8x long-context concurrency on a single H100; weights on Hugging Face.
NVIDIA Nemotron 3 Embed 8B Tool
8-billion-parameter retrieval encoder that turns queries and documents into normalized dense vectors for semantic search. NVIDIA claims state-of-the-art results on the multilingual RTEB leaderboard as of July 16; released under OpenMDW 1.1.
NOOA Tool
NVIDIA's open agent framework, contributed as the flagship technical artifact of the Open Secure AI Alliance. Its README is candid that it is research software and that its generated-code checks are not a containment boundary, so run agents in OS-level isolation.
Cosmos3-Edge Tool
NVIDIA's compact 4-billion-parameter physical-AI model generates text autoregressively while producing image, video, audio and action-trajectory outputs through a diffusion tower, sized for local robotics, autonomous-vehicle and smart-infrastructure workloads. NVIDIA warns it is not physically accurate simulation or safety-certified reasoning.
