Banger release from NVIDIA. They just published a report on NeMo Data Designer, their open-source synthetic data tool. It's a declarative config which makes a synthetic data pipeline easy to review, share and rerun. In NDD, a person or an agent defines each dataset column in a config file. Column types include generated text, code, structured output, images, embeddings and statistical samplers that control diversity. Plugins add new types. The workflow is built around previews. You generate a few records, check them, adjust the config and then run at full scale. The runtime handles column dependencies, calls to your model endpoints and retries. The paper includes Nemotron case studies. About 9K JSON-schema tasks made with NDD raised Nemotron Nano v3 from 80.2% to 86.9% on JSONSchemaBench. Paper: academy.dair.ai/papers/nemo-…

🤩 What a cool model release! Virtually every model we interact with is trained to be a helpful assistant. Clear, thorough, consistent. Real people are none of those things. They withhold information, dole it out a piece at a time, change their minds, get impatient, push back.
For AI to work with us, it needs to understand us Today, we're introducing Persimmon, the first large-scale model designed to realistically simulate how people talk and interact

Being able to model that complexity and diversity of behavior opens up so many cool opportunities to evaluate and improve the systems we build.

And the best part? The first release is based on our open-source Nemotron-3-Ultra model, the only model in the multi-user turing test that scored meaningfully above zero. 💚

Nemotron Personas chez les belges!
Belgium!!!! 🇧🇪🇧🇪🇧🇪 They... even... have the name of my village correct in all languages! And didn't forget about the violet guys! This is a lot of fun (for me and like 3 other people on this website).

as with a lot of Nvidia work: platforms are boring (good) platforms make the world work (great) Users might not know their experiences are running on an Nvidia GPU, and they might not know that the product was built on Nemotron. But they love what they’re getting.
"We're completely dedicated to this" working on Nemotron 4. Nvidia's open source AI model efforts do not get enough coverage

Today we're releasing Nemotron 3 Nano Omni. Audio, Video, Image, Text ➡️ Text Ask questions about all your data. Amazing efficiency powered by the Nemotron Hybrid SSM MoE architecture. State of the art multimodal intelligence.

Nemotron Personas France combines many of the things that make me so enthusiastic about Nvidia & open-source AI: - Open Data - Awesome AI Startup collaboration with @pleiasfr - NeMo Data Designer - Nemotron 3 Super NVFP4 - Nvidia GB200 Hardware Was nice to contribute to this!
Breaking: @pleiasfr and @nvidia release the first open synthetic dataset for personas in Europe: Nemotron-Personas-France. 1M synthetic French persons, with rich imaginary lives grounded on (complex) demographic distribution.

If you need some synthetic personas/people for your data projects, my team just put out a CC-BY-4.0 open dataset on HF of 100k folks matching US-census distributions for your free use. nvidia/Nemotron-Personas

1/6 The Nature paper highlighted by @alexandr_wang raises concerns about synthetic data and model collapse. However, it overlooks the transformative potential of synthetic data in AI. Far from causing collapse, modern approaches enhance model performance and capabilities.
1/ New paper in Nature shows model collapse as successive model generations models are recursively trained on synthetic data. This is an important result. While many researchers today view synthetic data as AI philosopher’s stone, there is no free lunch. Read more 👇

Excited to share our work on alpha-synuclein and N-terminal acetylation led by talented and recently graduated @Saranya_S_Kumar out in @ScienceAdvances! With vital contributions from Nima Naseri and @LaserSharkLab, check out thread below!

Trump: You know, our doctors get more money if someone dies from COVID Truth: I took a 20% pay cut due to less patients. Lost 3 colleagues & 27 y.o. cousin. Cried countless times delivering news of deaths to families. I'm doing more for the U.S. than you!

In tonight’s presidential debate the President said the “Portland Sheriff” supports him. As the Multnomah County Sheriff I have never supported Donald Trump and will never support him.

This isn't just Trump's disrespect for Biden coming through. It's his disrespect for the election process entirely. This constant litany of interruptions and lies deprives voters of the opportunity to actually hear a real debate.

The debate thus far is such a clear articulation of Trump's politics: constant deflection, constant interruption, zero substance
