What is the difference between LeakGAN and LM for text generation?

[guotong1988]

I'm new to LeakGAN or SeqGAN or TextGAN. I know GAN is to generate text and let discriminator un-judge-able to real text and gen-text.

LM(language model) is the task of predicting the next word and can also be used to generate text.
