Unique: Qwen2.5-1.5B's instruction-tuning includes explicit system prompt handling, making it more reliable at following system instructions than base models. The model distinguishes between system, user, and assistant roles through special tokens, enabling cleaner behavior conditioning than simple text concatenation.

vs others: More reliable at following system prompts than base models like Qwen2.5-1.5B-Base due to instruction-tuning; simpler to implement than fine-tuning-based customization but less precise than task-specific fine-tuned models.
