Nvidia Acquires Gretel AI in a Nine-Figure Deal to Boost Synthetic Data Capabilities!

Nvidia has acquired Gretel, a San Diego-based synthetic data startup, in a nine-figure deal exceeding $320 million.

The acquisition, first reported by Wired, reinforces Nvidia’s commitment to AI model training, addressing growing concerns over data scarcity, privacy regulations, and ethical limitations surrounding real-world data collection.

With this acquisition, Gretel’s 80 employees will be absorbed into Nvidia, allowing the company to integrate synthetic data generation into its expanding AI services.

“Gretel and its team of approximately 80 employees will be folded into Nvidia, where its technology will be deployed as part of the chip giant’s growing suite of cloud-based, generative AI services for developers.” — Wired

This move follows Nvidia’s recent investments in AI synthetic training models, including its Omniverse Replicator and Nemotron-4 340B, which allow developers to generate custom AI training data.

Why Synthetic Data? Nvidia’s Long-Term Vision

AI models rely on vast amounts of data for training, but accessing high-quality, unbiased, and legally available data has become increasingly difficult.

Synthetic data—computer-generated data designed to replicate real-world information—is emerging as a critical alternative.

Gretel, founded in 2019 by Alex Watson, John Myers, and Ali Golshan, provides a platform that fine-tunes open-source models, adds differential privacy features, and packages them for AI training.

The company raised $67 million in venture funding before its acquisition.

“Unlike human-generated or real-world data, synthetic data is computer-generated and designed to mimic real-world data.” — Wired

Huang’s statement underscores Nvidia’s commitment to synthetic data as a long-term solution to AI’s data bottlenecks.

The Risks: Will AI Models “Collapse” Under Synthetic Data?

Despite its promise, synthetic data comes with risks. A 2024 study published in Nature warns that repeated AI training on synthetic data could lead to “modelcollapse”— where models gradually degrade in accuracy.

“Put another way, if you feed the machine nothing but its own machine-generated output, it theoretically begins to eat itself, spewing out detritus as a result.” — Wired

AI researchers like Ana-Maria Cretu, a postdoctoral researcher at École Polytechnique Fédérale de Lausanne, acknowledge the issue but suggest that it can be mitigated.

She said, “You might possibly be able to get around model collapse by having fresh data with every new round of training.” — Ana-Maria Cretu

This has led to a growing hybrid approach, where companies combine real-world human-labeled data with synthetic data to maintain accuracy and reliability.

Big Tech’s Race for Synthetic Data

Nvidia’s move mirrors broader industry trends.

“We know that all of the big tech companies are working on some aspect of synthetic data.” — Alex Bestall, Rightsify Founder

These developments indicate a shift where AI companies are moving beyond internet-scraped data and toward controlled, synthetic datasets that they can legally own and modify.

The Future: Nvidia’s Competitive Edge in AI

By acquiring Gretel, Nvidia is reinforcing its dominance in AI infrastructure.

The move signals that synthetic data will play a central role in AI development moving forward.

However, the key question remains: Will synthetic data be enough to sustain AI model training without causing long-term degradation?

While experts remain divided, Nvidia’s investment suggests that the industry sees synthetic data as essential to overcoming data scarcity challenges.

As AI regulations evolve, Nvidia’s ability to balance synthetic and real-world data will determine the success of this high-stakes bet.
