OpenAI has released its most advanced models yet: o3 and o4-mini.
These models think longer before responding, combining all of ChatGPT’s tools — from web browsing and code execution to image interpretation.
o3 sets new standards in coding, math, and science reasoning. Meanwhile, o4-mini delivers fast, cost-efficient performance, topping benchmarks in competition math.
Both models were trained to decide when and how to use tools, solving complex tasks in under a minute.
Smarter, more capable, and fully equipped — o3 and o4-mini are now available across ChatGPT plans.
