GPT-4 is a large multimodal model that performs at a human level on various professional and academic benchmarks, including passing a simulated bar exam. However, it still faces limitations like "hallucinating" facts and making reasoning errors, which raise safety and ethical concerns. OpenAI has adopted various mitigation strategies for safer deployment, like adversarial testing and a model-assisted safety pipeline, but acknowledges their limitations and the need for ongoing research.

The authors are affiliated with OpenAI, the organization that developed GPT-4. This presents a potential conflict of interest as the authors have a vested interest in presenting GPT-4 in a positive light.

This is a strong research report that provides valuable information on a novel and rapidly evolving field. It performs well in many areas but still hallucinates facts and makes reasoning errors. There are also unresolved safety and ethical concerns with the release of this model due to its potential impact on society. The lack of transparency regarding methodology also lowers the rating.
