ChatGPT-maker OpenAI's Co-founder Sam Altman said the problem of AI hallucination is "real" and "we're working to improve it". "It's a balance between creativity and accuracy and we're trying to minimise the latter," Altman said. I trust ChatGPT's answers "the least on Earth", Altman jokingly said. AI hallucination is an AI's confident response that doesn't seem justified by data.
