0941 GMT - Organizations that deploy artificial intelligence need to define their objectives to keep costs from the technology at bay, Swami Sivasubramanian, Vice President of Agentic AI at Amazon Web Services, says at the HumanX AI conference in Amsterdam. "If you don't know precisely what is the return on investment you're after, what ends up happening is teams keep saying let's actually keep improving," he says. He compares the use of AI without a clear purpose to a vehicle going around a roundabout without knowing which exit to take. "You end up spending more fuel, or in the AI landscape, you end up spending more tokens and budget all the time," he notes.
