@ErikUden Even the lead author himself says that he used AGI in the title of that paper to garner attention. And the authors also clarify that it is really hard to judge the performance of LLMs when you don't know what they were trained on. They work fairly well for some tasks that suggest general understanding of the physical world and fail spectacularly on similar tasks with minimal changes.

"LLMs are AGIs" is PR by companies like OpenAI, not science.
