They fine-tuned a Llama 13B LLM with military specific data, and claim it works as well as GPT-4 for those tasks.
Not sure why they wouldn't use a more capable model like 405B though.
Something about this smells to me. Maybe a way to stimulate defense spending around AI?
Looking past all the red scare/ai bullshit, it's probably a nothingburger. Researchers funded by the Chinese equivalent of DARPA doing something they thought would be cool.
