The painful irony of bragging about/lamenting your new model's cybersecurity capabilities within and in response to leaking all the information about it due to poor cybersecurity. Can't wait for the "$LAST_MODEL was amazing but this is the one that will change everything."

The "every new model is THE one" cycle is getting a bit old but the Capybara tier thing is actually worth paying attention to.

Big if true. Any alleged "step change" over 4.6 is worth paying attention to. Also, Hegseth did a big fucky wucky if true - since they went scorched earth with Anthropic, this could mean denying the US frontier model capabilities. It would be pretty amusing if Anthropic emerges as the clear winner (for some period of time) and other governments can use them but the US government cannot. Current admin is certainly too prideful to walk something like this back. After all, admitting mistakes is unmasculine, and we have very manly men in charge of war round these parts!

would be hilarious if they get declared a SCR and end up with the best model
