What makes you think so?
Most of the stuff I've read, my personal experience with the models, and my understanding of how these things work all point to the same conclusion:
AI is great at summarization and classification, but totally unreliable with generation.
That basic unreliablity seems to fundamental to LLMs, I haven't seen much improvement in the big models, and a lot of the researchers I've read are theorizing that we're pretty close maxing out what scaling training and inference will do.
Are you seeing something else?
