 Limitations  We are still working on understanding the behaviors of these models, but here are several issues we have found: - Models are generally sensitive to the instruction. Sometimes rewording the instruction can lead to very different output. - Models are not always compliant to the instruction. Sometimes the model don't follow your instruction (e.g., when you ask the model to generate one sentence, it might still generate one word or a long story). - Models might totally fail on some tasks.  If you find serious issues or any interesting result, you are welcome to share with us!
