Assessment

Highest AA Intelligence Index v5 score (60, re-scored under v5.0.1), second on Terminal-Bench 4.0 (65.2%) behind Kimi K3.1 Pro, and first on AA-Omniscience at 53.5. Access is restricted, though: only vetted organisations in Google's Fairwind programme can use it, with no public API or App timeline. Raw factual accuracy is 58% and its 11% hallucination rate is higher than Argon's 4%. The $2/$10 launch promo has ended; the regular price is now $4/$20 ($0.2 cache hit).
