India, April 3 -- OpenAI's GPT-4.5 and Meta's LLaMa models have passed the Turing Test, a benchmark proposed by Alan Turing in the 1950s to assess whether a machine can exhibit intelligent behaviour indistinguishable from humans. A pivotal moment for conversational AI, one easily eclipsed amid a flurry of intriguing developments, including ChatGPT's Ghibli imaging, pursuit of Agentic AI (human-like responses are especially relevant for this frontier), breakthroughs in cancer detection using AI, and Google unlocking a 'thinking' Gemini 2.5 model.

Though not the first AI models to pass this test, it is one of the most noticeable among recent contenders. GPT 4.5, released in 2023, exhibited most human-like behaviour in the tests, where it f...
