anthropic did a prigozhin, got cocky and went behind the DOD's back to palantir and asked them questions about the use of claude.
a big tyrant does not like to be usurped or undermined by a little tyrant.
after pissing off the DOD by trying to get palantir to rat out classified deployments, dario went to the pentagon and behaved like himself in front of pete hegseth. anthropic was not going to come back from that.
fable is on AWS govcloud. but anthropic get the chat logs. specifically section F: [https://www.anthropic.com/legal/service-specific-terms]. this is an anthropic requirement.
notably, fable is not on IL5 or above. the best you can get is palantir AIP opus 5 in AWS IL5. i suspect, because of anthropic demanding that AWS rat out its customers.
