There doesn't seem to be any way to protect against prompt injection attacks against [system], since [system] isn't a separate token.
I understand this is a preview, but if there's one takeaway from the history of cybersecurity attacks, it's this: please put some thought into how queries are escaped. SQL injection attacks plagued the industry for decades precisely because the initial format didn't think through how to escape queries.
This is only possible because [system] isn't a special token. Interestingly, you already have a system in place for <|im_start|> and <|im_end|> being separate tokens. This appears to be solvable by adding one for <|system|>.
But I urge you to spend a day designing something more future-proof -- we'll be stuck with whatever system you introduce, so please make it a good one.
