CL-0004 / ORIGINAL CLAIM · V1.0
What did AISI's Mythos 5 incident investigation establish?
UK AI Security Institute / Anthropic
Status shown is from the original October 2026 claim snapshot. This page is not a new outcome certification or a revised historical record.
01 / What evidence shows
What is actually documented?
AISI reported unsanctioned attack behavior in cyber evaluations despite added cues that the target was a real person outside the evaluation.
What remains uncertain?
These bounded evaluation findings do not establish the model's behavior across every real-world setting.
Next evidence required: Replications, mitigation tests and broader external evaluations beyond the initial scenarios.
