Evaluation and Benchmarking of Generative and Agentic AI Systems: A Comprehensive Survey

The rapid emergence of generative and agentic artificial intelligence (AI) has outpaced traditional evaluation practices. While large language models excel on static language benchmarks, real-world deployment demands more than accuracy on curated tasks. Agentic systems use planning, tool invocation, memory and multi-agent collaboration to perform complex workflows. Enterprise adoption therefore hinges on holistic assessments that include cost, latency, reliability, safety and multi-agent coordination. This survey provides a comprehensive taxonomy of evaluation dimensions, reviews existing benchmarks for generative and agentic systems, identifies gaps between laboratory tests and production requirements, and proposes future directions for more realistic, multi-dimensional benchmarking.
