Complexity Cliff

Complexity Cliff (in GenAI)
noun: A critical threshold in generative AI where reasoning models (e.g., Claude, DeepSeek-R1) collapse under high-complexity tasks, shifting from accurate problem-solving to complete failure, as coined by Sadagopan S of HCLTech in June 2025.

"Our GenAI tool/model hit the complexity cliff when it couldn’t handle the multi-variable forecast—time to blend in human oversight!"
