MIT CSAIL Finds LLMs Developing Simulations of Reality as Language Skills Advance

Full Article

Researchers from MIT's CSAIL have found that large language models (LLMs) can develop their own understanding of reality to improve their generative capabilities. By training an LLM on over one million Karel puzzles without direct instruction, the model created its own internal simulation of the tasks. This challenges existing beliefs about the necessary information for learning linguistic meaning and suggests LLMs may achieve deeper language comprehension in the future.

The study revealed that as the LLM's ability to solve puzzles improved, so did its internal understanding of the instructions. The research indicates that LLMs undergo a developmental process similar to how children learn language, progressing from simple babbling to meaningful instruction generation. This work raises important questions about the nature of understanding in AI and whether LLMs can truly grasp the semantics of language.

• LLMs can develop internal models of reality during training.

• Research suggests LLMs may achieve deeper language understanding.
