Hi, I have been trying to get the chatml template to work with llama.cpp as the quality of the answers I am getting is really, really bad and sometimes the model hallucinates new roles, starts talking to itself, starts writing down notes... Something is off.

./llama-cli --verbose --model llama-3-8b-instruct-f16.gguf -p "System Prompt\n" -n -1 -fa -sp -if --mirostat 2 -co --penalize-nl -r "USER:" --in-suffix "AI:" --in-prefix "USER:" --chat-template chatml

Unfortunately nothing seems to be working properly (enabling -cnv, trying to write out the chatml format manually) even though chatml should be accepted as a --chat-template. I have never really managed to get chat working well in llama.cpp and I would like to be able to do so.

Thank you in advance for your time and patience.
