The Opportunity

Problem

AI systems produce inconsistent outputs for identical inputs because vector databases rely on non-deterministic floating-point arithmetic that varies across CPUs and hardware.

Solution

ReproTest runs automated test suites that execute identical AI pipelines on multiple hardware profiles and flags any output divergence. It integrates into CI/CD and generates pass/fail reports with exact diff locations. Teams get immediate alerts when new model versions or library updates introduce non-determinism.

Target Audience

AI engineers and platform teams building reproducible, auditable, or safety-critical systems in finance, healthcare, SRE, multi-agent operations, and AI alignment research.

Differentiator

First CI-native reproducibility testing platform purpose-built for vector and embedding workloads.
