You should include a link to a news article

I don’t know that it hit the news yet. I believe this was a explanation to current users.

Here we go:

Being the US government, one might question whether this is actually for national security or just trying to skew competition to reward friends and/or punish enemies

I don’t know. The government did the same with cryptography. But this thing can either secure you system or break it. I first heard of it on Security Now with Steve Gibson.

I’ve been told by a user that this was released because the authors wanted to force regulation on Ai. Remember a couple months ago Anthropic didn’t want there models used for war purposes. That is rumor though.

They shutdown the Mythos class model 3 days after it was released with their stated reason being bc it did stuff that other non-Mythos class models have already been doing for several months.

Strikes me more as a precedent setting power play to accumulate additional authority and control than as an attempt to protect people. Aka a lie and yet another distraction
