Openai is planning to ship an update to the chatgpt that will turn on the new O3 Pro model, which has more calculation to think hard.
Currently, Chatgpt provides O4-Mini, O4-Mini-HIGH, GPT-4.5, GPT-4.1, GPT-4.1-Min, and O3 $ 20 Plus for customers.
Chatgpt $ 200 Pro Subscription has an O1 Pro model with all those who provide more calculations to think hard.
The O1 Pro is powerful, but it feels old because we have a better O3 model in the lineup. However, it may soon change with the O3 Pro model.

As Indicated At an event in New Delhi, Openai will soon swap the O1 Pro for the O1 Pro, which will give Pro users more power to solve difficult problems.
While the O3 already performs better than the O1 on the benchmark, the O1 Pro offers additional calculations for better reliability on difficult tasks.
Earlier, the O1 Pro made both O1 -RVIEW and O1 better on hard benchmarks, including matchmaking competitions, coding challenges and PhD-level science questions on hard benchmarks.
The O3 Pro is expected to combine strong basic arguments of O3 with those reliability benefits. This will increase the thinking capabilities of the existing O3 model and allow Pro users to more.
Openai may announce O3 Pro for $ 200 Pro customers next week or late this month.
