This research looks at how well large language models (LLMs) like GPT-3.5 and GPT-4 can be used to improve safety in the construction industry. Construction is a dangerous job, and these AI models could help keep workers safe by providing information and identifying hazards. Researchers tested these models using questions from real safety certification exams and found that both models did well, scoring better than the passing grade. GPT-4 did even better than GPT-3.5, showing that larger models with more training data perform better. The study also looked at how different ways of asking questions, called "prompt engineering," can affect the models' answers. They found that there's no one best way to ask questions and that the best approach depends on the specific model and the ty ...
