The Turing Test is a test of a machine's ability to exhibit intelligent behavior indistinguishable from that of a human. Proposed by Alan Turing in 1950, the test involves a human evaluator interacting with both a human and a machine without knowing which is which. If the evaluator cannot reliably distinguish the machine from the human, the machine is considered to have passed the test. The Turing Test is a foundational concept in artificial intelligence, representing a benchmark for assessing the advancement of AI systems in terms of natural language processing, understanding, and generating human-like responses.
