  "textContent": "BARCELONA, March 5, 2026 — The cost of running a state-of-the-art AI model dropped 100-fold in 18 months while quality improved 50 percent, OpenAI Board Chairman **Bret Taylor** said Wednesday at Mobile World Congress here. That compression, he said, would drive the price of a single customer service call toward one cent.\n\nTaylor is also CEO of Sierra, a Silicon Valley startup that deploys AI agents for enterprise customer service. The former co-CEO of software-as-a-service giant Salesforce, Taylor is chairmann of the AI giant of which **Sam Altman** is the CEO.\n\nGPT-4, OpenAI's large language model, cost $60 per million output tokens three years ago, Taylor said. Its successor, GPT-4o, now costs 60 cents per million output tokens and scored 50 percent higher on human evaluation benchmarks, he said.\n\n### This post is for subscribers only\n\nBecome a member to get access to all content\n\nSubscribe now",
