Lots of "in collaboration with Claude and Anthropic Research" mentions, no mentions of other labs. I'd assume Apple already had access to whatever the most powerful model is at the various US-based labs, but perhaps not?

I wouldn't say 4 is lots. The entire list is massive. I haven't counted myself, but someone claimed that macOS 26.6 has the all-time record with 155 CVEs.
also “ Using GLM From Z.AI”
Apple also hosts a copy of Claude internally in their servers.
Those were voluntary disclosures by two Anthropic researchers and the security firm Calif. I know one more CVE on the list that was discovered using an AI agent and wasn't disclosed as such. I suspect there are many more.
