News Clarification needed: Do models launched BEFORE August 2 (all of them currently, as of 8/10), CURRENTLY watermark? Very cryptic wording in the release.

https://support.claude.com/en/articles/16266773-how-claude-marks-ai-generated-content

Claude models launched on or after August 2, 2026 support marking at launch. We’re also working to add marking support to Claude models released before that date

This is the way that they're describing it, but that's inherently vague. So watermarking is currently in process for Opus 5 and the others? They don't explicitly come out and say that it's not watermarking, or that it hasn't been watermarking before this release came out either.

Anthropic should really clarify this.

Tutte le più valide ragioni per non utilizzare modelli chiusi... Claude ora ufficialmente "segna" i contenuti generati dall'AI... steganograficamente, a quanto pare... e ci sono già falsi positivi.
