A practical map of LLM evaluation risks: hallucination, prompt sensitivity, bias, contamination, and brittle benchmarks.
Why NLP evaluation needs metrics, uncertainty, human judgment, and task-specific error analysis.
Why LoRA and adapters are useful when full fine-tuning is too expensive or unstable.
Prompting as task specification, interface design, and evaluation risk.
