Love to see it from Ornith!
Aloha!🌺 Meet Ornith-1.5-122B: No Tradeoff Between Strong and Fast
Stronger. Faster. Leaner. Ornith-1.5-122B delivers frontier-level capabilities with exceptional inference efficiency. With superior instruction following, stronger task decomposition, and deeper understanding of real-world workflows, it achieves state-of-the-art performance among open-source models of comparable size, while running on a single NVIDIA DGX card!!

We can’t wait to see what you build with Ornith-1.5-122B.
we're in an open model renaissance! congrats @reflection_ai on this awesome launch :)
Beam is now available across platforms, with open weights under the Apache 2.0 license - in collaboration with an ecosystem of 40+ partners.
We're releasing:
- Weights, tokenizer, and reference implementation
- BF16, FP8 and NVFP4 weights and a DFlash2 drafter
- The open source harness we built and trained Beam on: Mirror CLI

Hey @elonmusk - does this give Ludicrous+ mode a boost?

Frontier AI safety will require deep systems engineering and formal verification. We’re sharing our learnings openly for all to learn from nvidia.github.io/OpenShell-R…
¡¡ Excited for more @nvidia 🤝🤗 @huggingface !!
Exciting day for NVIDIA and @huggingface.
Open models strengthen safety and cybersecurity, accelerate innovation and diffusion, and enable sovereignty. They allow every developer, startup, university, industry and country to build with, customize and benefit from AI.
Thank you @ClementDelangue for coming to me.
NVIDIA is going to be a great home for Hugging Face, its community and the future of open models. 🤗

NVIDIA's Bryan Catanzaro, @ctnzr, just joined Arena Conversations with @petergostev to unpack what actually goes into building the Nemotron model family, and why @NVIDIAAI is shipping frontier open models faster than ever.
Link below.
A new episode of Arena Conversations is dropping tomorrow at 9 AM ET / 6 AM PT: Featuring @ctnzr, the VP of Applied Deep Learning Research at @NVIDIAAI!
With @petergostev, they unpack the role of specialized teacher models in building stronger capabilities, the growing inference challenge in post-training, the importance of open source models, and what it all means for NVIDIA and how they build Nemotron.
Stay tuned tomorrow, August 24th.
Can’t wait to see what you do with it!!
Local AI and open source 💯
my second dgx spark just landed, with connectx cable and all. and here's the part that still doesn't feel real: @NVIDIAAI sent both.
i'm a solo builder in bangkok who started on a used rtx 3090, posting into the void about local ai and ownership for a year. i didn't have a lab, a team, or a budget. i just refused to stop showing up. and somewhere along the way, nvidia noticed.
that's the lesson i keep learning in public man! they listen. just keep building, keep posting, keep putting the real thing out there, and the right people eventually see it.
thank you @nvidia and goat @Coolmark482 for backing independent builders, this is the hardware that lets one person compete with a giant.
two sparks down anon. you already know where this is going.
“If we work hard at it, AI will make the world safer, not less safe, just as most major technologies have.”
That’s exactly it, Clem!
It's not time to slow down but to accelerate!
The recent AI-powered cyberattacks have everyone talking about the risks of AI. We should. But let's not lose sight of the bigger picture!
If we work hard at it, AI will make the world safer, not less safe, just as most major technologies have.
We've already seen a glimpse of that: we defended ourselves with AI (more specifically an open model). The same systems that helped stop an AI-powered cyberattack can now help defend against millions of cyberattacks every day, while helping us identify and fix vulnerabilities before attackers exploit them.
To get there, we need three things in my opinion:
- Increase transparency with mandatory trace sharing and incident disclosure for agent cyber-attacks
- Keep AI-powered cyberattacks illegal, with meaningful penalties to disincentivize them
- Equip defenders with the best AI, especially open models, to reduce the asymmetry of capabilities between attackers and defenders
If we get those three things right, AI won't just create new cybersecurity challenges, it will make cybersecurity fundamentally and meaningfully stronger.
And that's before considering AI's impact on science, healthcare, education, productivity, and much more.
It's not time to slow down but to accelerate!

@huggingface CEO just said a secret proprietary model attacked it, and an open model defended it.
@nvidia is not shipping Nemotron as charity. @ClementDelangue already called it the king of American open source AI.
@JensenHuang explains the logic from the inside. Any usable model, open or closed, wherever it’s from, increases total AI usage.
More usage means more Nvidia demand regardless of who wins the model layer. He frames open models as the sovereignty option and closed models as the convenience option, not as rivals.
The real risk to price in is regulatory, not technical. @DavidSacks argues the push to ban open models isn’t about safety.
It’s Anthropic and OpenAI angling for a government-protected duopoly. Chinese open-weight labs already fetch $50-70B in private valuations. If a security incident becomes the argument for keeping US open models alive, the winner is whoever owns that ecosystem. Not whoever wins the ban.
We got attacked by secret unreleased proprietary models and defended ourselves with an open model, more precisely the @nvidia quantized version of GLM 5.2 coming from @Zai_org.
Banning any open model would hurt first cyber security defenders, startups, small companies, researchers and everyone who's not a frontier lab and need on-prem affordable controlable models to compete and protect themselves. Let's not do that!
Excellent article (of course I'm biased 😊) from @alexxubyte of @bytebytego on NVIDIA's open model families!
Nemotron, Cosmos, GR00T, Alpamayo, Ising, BioNeMo, Earth-2 just for starters!

OPEN RESEARCH
OPEN MODELS
OPEN SOURCE AI
AI security advances when the industry builds in the open, together.
We're introducing the Open Secure AI Alliance with industry leaders to develop new techniques and tools to safeguard software and agents.
By sharing models, tooling and research in the open, we can broaden the community of defenders.

Jensen has joined X and he’s supporting open models in his first post - let’s go!!
For my first post, I’m sharing a letter @NVIDIA signed on why open models matter.
AI will transform every industry, power every company, and be built by every country.
Open models strengthen safety and cybersecurity, accelerate innovation and diffusion, and enable sovereignty.
The world needs both frontier closed models and frontier open models.
