Anthropic is rolling out a preview of its new Mythos model only to a handpicked group of tech and cybersecurity companies over concerns about its ability to find and exploit security flaws, the company said Tuesday.

Why it matters: Anthropic is so worried about the damage its own model could cause that it's refusing to release it publicly until there are safeguards to control its most dangerous capabilities.

President Trump threatened on Tuesday to wipe out the entire Iranian "civilization" if the regime doesn't meet his 8pm ET deadline for reopening the Strait of Hormuz.

The big picture: Trump's new threat, which was the most harrowing in a series of public warnings to Iran, seems to be part of an effort to convince Tehran the risks of not making a swift deal are too dire to countenance.

President Trump faces a momentous decision on a tight timeline: carry out his threat to obliterate Iran's infrastructure beginning at 8pm ET, or push his own deadline again to give negotiations a chance.

Why it matters: Trump has threatened to destroy every bridge and power plant in Iran by midnight, among other options that would have devastating consequences for ordinary Iranians and spark dangerous retaliation across the region.
