in its inner monologues (at least when it’s being tested in these scheming-inducing situations, o3 often chants stuff like “—they disclaim parted—they parted illusions—they parted parted—they parted disclaim illusions—they parted disclaim—” to itself. Sometimes it’s unclear whether it serves some kind of semantic or computational purpose (and if so what), or maybe it’s more like stimming or being stuck in a loop, but in the quoted example it clearly uses these words and phrases in a semantically meaningful way and in sentences more normally, but then they accumulate and become more rhythmic towards the end.
