Back to Regression Database
For AI Tool Vendors

Vendor Portal

Respond to patterns, track fix status across versions, and publicly demonstrate improvement. Vendors are participants in this database, not just subjects.

How Vendor Notification Works

1

Pattern Submitted

A community member or maintainer submits a new regression pattern with reproduction steps.

2

Initial Review

Database maintainers verify the pattern is reproducible (>= 3/10 attempts) and meets documentation standards.

3

Vendor Notification

Your team is notified 7 days before publication. You receive the full pattern, reproduction steps, and severity assessment.

4

Response Window

You have 7 days to file a response that will be published alongside the pattern. Responses are never edited.

5

Publication

The pattern goes live with your response attached. You can update status anytime as fixes ship.

What Vendors Can Do

Respond to Patterns

Submit official statements during the 7-day notification window. Responses are published verbatim alongside the pattern.

Mark Fixes

Update pattern status to "fix planned" or "fix shipped" with the version. The test harness verifies fixes weekly.

Track History

View complete testing history: reproduction rates over time, which patterns were fixed, and how your fix rate compares.

Reproduction rates are averages across all open patterns. Test dates reflect automated harness runs (API tools) or community reports (IDE tools).

Register as a Vendor

Registration requires a verified corporate email domain. We verify your identity before granting access to respond to patterns and update fix status.

Our Commitments to Vendors

Neutral Infrastructure

The database documents patterns, not rankings. We never frame results as "which AI is worst." Every tool has failure modes.

Public Recognition of Fixes

When your tool fixes a pattern, we publicly recognize the improvement. Fixed patterns remain as a record of your responsiveness.

Version Awareness

We test against your latest versions. Old patterns are not used to characterize current performance. The database tracks improvement.

Unedited Responses

Your official responses are published exactly as submitted. We never edit, summarize, or misrepresent vendor statements.
