Gretel / NVIDIA

Gretel was acquired by NVIDIA in 2025; NVIDIA now positions synthetic-data generation for agentic AI through NeMo. The availability of Gretel's former standalone platform is unconfirmed. 1

Product status changed

Manufacturer / project: Gretel / NVIDIA

When does it fit?

Best aligned with domain-specific synthetic text and datasets for AI-agent training, evaluation, and adaptation in NVIDIA's current NeMo Data Designer workflow. 1 · 2

Fit still depends on your mandatory requirements.

What should you check before choosing?

Do not present the former Gretel SaaS/API as currently purchasable: acquisition is confirmed, but current standalone service availability, support, and terms remain unverified. 1 · 2 · 3 · 4

What must your PoC prove?

Use a parent/child fixture, one invalid row and a fixed expected result. Check cleanup after failure, restore the configuration and repeat with pinned inputs. Unresolved requirements need a demonstration.

Acceptance plan, not a product test result. Execution scope and limits.

Deployment and license

NVIDIA's current use-case page directs users to NeMo Data Designer and documentation; Gretel-branded service hosting options were not confirmed. 1 · 2 · 3 · 4

Current Gretel-specific pricing and licensing were not confirmed. NVIDIA product and service terms apply only where the current NeMo product is selected. 1 · 2 · 3 · 4

Confirm the entitled version and operating requirements.

How you work with it

Current NVIDIA documentation describes NeMo synthetic-data workflows; confirm the exact component and runtime rather than assuming former Gretel service behavior. 1 · 2 · 3 · 4

Export does not establish compatibility with another runtime.
