Original GitHub issue: https://github.com/ollama/ollama/issues/805

Different models have different names for the roles (eg USER, ASSISTANT, AI).

This is how llama.cpp handles them:

I didn't find any specification of reverse-prompt anywhere. Do you know if it is used?

I found templates, like

USER: {{ .Prompt }}
ASSISTANT:

for Vicuna and

[INST] {{ .Prompt }} [/INST]

for Mistral.

Roles are defined in the Modelfile. You can see the Modelfile of a particular model with ollama show --modelfile <model>.

My question is actually: do you use reverse prompts? Can Vicuna have "USER:" in its output?
