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.

🤩 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.
🎭 We are organizing the first dedicated workshop on user simulation at @NeurIPSConf this December! Submit a workshop paper, join us in Paris, or share with friends and colleagues working on how AI systems represent, simulate, and interact with users. usersim-workshop.github.io/
We have a phenomenal program in the works, courtesy of a pretty awesome organizing team. 🙇♂️ Victor Barres, @flosalim, @krisztianbalog , @Preethi__S_

📍 Workshop: In person in Paris, December 12 or 13
📅 Submission deadline: August 29, 2026, AoE

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.

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!

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.

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.

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!
🎉Thrilled to announce my first, first-author paper in @ScienceAdvances! 📝Delved into alpha-synuclein biology using CRISPR screens, unveiling new insights and potential therapeutic targets for #Parkinson. 🧬

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.
Yev Meyer retweeted
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.
