1. it's not cheap to run glm-5.2 so not just anyone can do it 2. just because you haven't heard of attacks doesn't mean they haven't happened 3. this attack in the article was performed by a prerelease model which presumably benchmarks a bit above Sol which benchmarks above glm-5.2
We went from gpt 3 to models discovering and chaining their own zero days in a couple years. I'm not sure what else "takeoff" could possibly look like?
