**TLDR:** LLM evaluation frameworks: MMLU (Hendrycks 2020) general knowledge, HELM (Stanford 2022) comprehensive, MT-Bench (Zheng 2023) chat, LMSys Chatbot Arena (community ELO ranking), GPQA (Rein 2023) graduate-level, HumanEval/MBPP code. Turkish benchmarks (TR-MMLU, MUKAYESE). Benchmark contamination concern, holistic evaluation.
