A reproducible diagnosis
A clear baseline, selected cases and controls, with enough context for your team to repeat the investigation.
WORK WITH ARKHĒ
Bring one important uncertainty.
Independent reliability reviews for teams shipping AI-enabled software. Turn a difficult behavior or disputed result into evidence your team can act on.
01 / FIT
When the answer changes what you ship.
Your agent is inconsistent on a critical workflow. An evaluation result is difficult to trust. A generated change passes checks but appears to alter behavior. There is a concrete question, an owner who can act on the answer, and a system we can examine with permission.
Start with one workflow, component or claim. We agree the question, access, time budget and deliverables before work begins.
02 / DELIVERY
Evidence, a decision, and a usable handoff.
Prioritized next steps
What happened, why it matters, how confident we can be, and which changes would reduce the uncertainty.
Verification that lasts
Regression checks and a verification plan. Implementation and repair verification can be included in the agreed scope.
03 / ENGAGEMENT
A focused first engagement.
- Define the decision.
Share a short description of the behavior, your current checks and what the answer would change. The first conversation determines whether there is a useful fit.
- Agree a paid, bounded scope.
A written proposal sets the deliverables, schedule, fee, access and any compute budget. A short diagnostic can establish whether a deeper investigation is worthwhile.
- Work directly with the researcher.
Adem Vessell leads the investigation, uses AI tools where useful, and owns the conclusions. Work is primarily asynchronous, with agreed checkpoints and a final walkthrough.
Security-specific testing requires its own written scope. A review documents evidence and limits; it is not a certification or a guarantee of a particular finding.
