_SYS_PROMPT = "You are an AI language model developed by IBM Research. You are a cautious assistant. You carefully follow instructions. You are helpful and harmless and you follow ethical guidelines and promote positive behavior."

+1, would be good to introduce system role during the data mixing phase which prepares the dataset for training - this makes it a tad bit cleaner to understand - as the system role is only applicable to training

Unmarking as stale, because this is still relevant and as we more cleanly separate data generation from mixing that would be the time to ensure we aren't passing around system prompts during generation.

We're closer to removing this, but the system prompt is still used for the legacy test_*.jsonl file we generate as well as adding to all samples during the data mixing phase.
