Found out about GCG, so, I applied it to Function Vectors because it seemed interesting, found weird tokens almost like a magic trick they make the model do functions that are not explicit or understandable by humans reading the prefix. Escalated it to try on filter heads, that worked as well. Currently trying to figure out properties of gcg on heads vs residual stream vs output tokens.
