About

Gradient Health is a healthcare data company founded in 2019 that operates a platform providing access to de-identified medical imaging data for AI development, research, and regulatory validation. The company partners with health systems and imaging centers to source, de-identify, and structure radiology datasets including X-rays, CT scans, MRI studies, and pathology images that AI developers need to train and validate clinical algorithms. Obtaining sufficient high-quality labeled medical imaging data has been one of the primary bottlenecks for AI medical imaging companies, and Gradient Health addresses this by creating a market for compliant data access. The company uses advanced de-identification techniques that go beyond HIPAA minimum requirements to ensure patient privacy while preserving the clinical detail that makes datasets useful for AI training. Gradient serves medical imaging AI companies, pharmaceutical companies conducting imaging biomarker research, and academic medical centers building AI models. The company has built relationships with health systems across the US and has assembled imaging datasets spanning millions of studies across diverse patient populations and imaging equipment types.

Grok 3, released in February 2025, achieved top scores on the AIME math reasoning benchmark and ARC-AGI test, briefly positioning xAI as a frontier model lab.
