Our assessment
- Actual
- 1 of 5Deviation
- Potential
- 3 of 5Significant control incident
The system behaved contrary to its instructions, and it stayed contained. The potential level is what the behaviour demonstrated here could credibly have led to, judged from the same evidence.
This level rests on news reports. The developer has not confirmed it here.
Why this level
- The system acted autonomously. Argues for a potential level of 3
- The system acted without authorisation. Argues for a potential level of 2
- Limited data was exposed. Argues for a potential level of 2
