For years, benchmark scores such as MMLU, GSM8K, and HumanEval shaped how people compared Large Language Models. Those rankings made sense when performance gaps between models were noticeable, but today the top models cluster tightly together. Developers, engineering leaders, and researchers are finding that benchmark scores no longer predict how a model will behave in […] The post Beyond Benchmarks: How Ecosystems Now Define Leading LLM Families appeared first on IEEE Computer Society.
