Why C-
The xAI Frontier Artificial Intelligence Framework (Jun 30, 2026) covers CBRN, cyber, loss of control and harmful manipulation in nine pages with few defined thresholds. FLI found no procedure linking threshold breaches to deployment decisions, which leaves the thresholds effectively non-binding.
C on this criterion means: Published framework with narrow scope, few or vague thresholds, mostly discretionary language, or commitments weakened from earlier versions.
