This shift marks the transition from AI as an assistant to AI as an autonomous digital worker.
OpenAI's GPT-5.4 has become the first model to score 83% on the GDPVal benchmark, a metric indicating that the AI can perform professional tasks across 44 occupations at a level equal to or exceeding human experts.
