Built for You

ML Engineers: You updated your model and something broke. DriftDune tells you what changed.

AI Platform Leads: Monitoring logs is not enough. DriftDune spots behavior change before it hits production.

Compliance Teams: No more invisible model updates. Get reproducible evidence of what changed, and when.

What It Does

• Compares old and new LLM outputs

• Detects semantic drift using OpenAI embeddings

• Flags meaningful behavior changes

• CLI-first — no dashboards, no overhead

Why DriftDune Exists

Model quality shouldn’t degrade silently. You deserve visibility, not surprises.

DriftDune is the `git diff` for your model’s behavior. Run it. Know it. Trust it.
