Safety frameworks cluster: Constitutional AI v3 + Preparedness v2 + Frontier Safety v3 + Llama Guard 4 + AI Red Team + C2PA 2.0 — every frontier lab ships a safety framework update

The week of 2026-08-05 saw a cluster of safety and governance announcements: Anthropic Constitutional AI v3, OpenAI Preparedness Framework v2, Google DeepMind Frontier Safety Framework v3, Meta Llama Guard 4 (open-weight safety classifier), Microsoft AI Red Team updates + AI Risk Shadow Model, C2PA Content Credentials 2.0 (cryptographic media provenance). The Decoder frames the cluster as 'every frontier lab ships a safety framework update'. The pattern: every frontier lab is publishing / updating its safety framework at the same cadence as its model releases, and the open-weight tooling (Llama Guard, C2PA) is shipping in lockstep.
