Built to generalize

We believe v3e is a generalized model of AI-written source code, and a future-proof one. It learns what AI-written code has in common rather than the fingerprint of any single model, so it keeps catching AI-written code as new models are released.

A score is a signal, not a verdict

A low false-flag rate is not zero, so the dashboard shows why a file scored high.

  1. Check the flagged listSubmissions scoring 70% or more are marked for review.
  2. Read the highlighted linesOpen a submission to see the regions the score rests on.
  3. Then talk to the studentUse the score to start a conversation, not to close a case.

Questions

How accurate is Codequiry's AI code detection?
Model v3e catches 90% of AI/GPT-written code and falsely flags 1.3% of human-written code.
Which AI models is it trained on?
Claude Opus 5.5, GPT-5.6 Sol and GPT-5.5 Codex submissions. It scores any code a student hands in, but detection can be weaker against models it was not trained on.
Is an AI score proof that a student cheated?
No. A score is a signal, not a verdict. Open the submission, read the highlighted lines and talk to the student before acting.
