simulate
Model real conditions around the release.
AI release rehearsal
Rehearse AI behavior before release.
Run production-like simulations of your AI system. See what changes. Get evidence. Decide with confidence.
Built for teams shipping AI systems that impact real users.
observe
Capture rank, retrieve, and act behavior.
return evidence
Artifacts, diffs, and signals you can trust.
decide
Ship, review, or block with confidence.
reuse & learn
Failures become memory for the next run.
02 / World Inputs
Build a production-
like world around
your system.
Determina recreates the conditions
that make behavior change in production.
03 / Observe Behavior
Observe whatthe systemactually does.
We watch ranking shifts, source paths,
and tool effects as behavior unfolds
in a rehearsal world.
Final answers aren’t enough.
Behavior observed
Live traces from rehearsal
world conditions.
Multi-layer instrumentation
Deterministic replay
Evidence you can trust
Better evidence. Better decisions.
Product Systems
Rank, retrieve, or act.
The same observation layer adapts to the behavior your release can change.

04 / Evidence Assembly
Evidence,
not vibes.
Every finding links to artifacts—traces, lenses, diffs, and verifier results—so your team can inspect, explain, and rerun with confidence.
05 / Decide & Remember
Decide before
rollout.
Ship, review, or block with bounded evidence. The decision stays yours; the lesson becomes reusable memory.
pilot intake
Bring the release your team is nervous to ship.
Send one system and one planned change. Determina rehearses the behavior, returns the evidence, and leaves your team with a reviewable decision.
pilot intakeWhat to send
- System
- Recommender, search/RAG, or agent workflow.
- Change
- Model, policy, source, or tool update.
- Concern
- The behavior your team wants checked before rollout.
- Return
- An evidence packet your team can inspect and reuse.
- 01 SendShare the system, planned change, and behavior concern.
- 02 RehearseDetermina runs the change in a production-like world.
- 03 DecideYou get traces, diffs, and a reviewable release packet.
