The wording in this post seems much more... restrained? than usual. Maybe Anthropic is afraid of exaggerating the capabilities and consequences of their new models to avoid government scrutiny and sanctions.

I wonder if Anthropic would still intentionally nerf their models without the threat of government intervention.
