Unified Evaluation for All LLM Tasks: LLMs indeed face a formidable challenge in catering to an extensive
range of tasks, each with its distinct set of demands. One crucial aspect lies in creating an evaluation framework
that can seamlessly adapt to this diversity. This framework must offer a consistent method to gauge performance,
regardlessofwhetherthetaskinvolvesstraightforwardquestionansweringordelvesintotheintricaterealmsofcomplex
