ChatGPT Pro plan provides unlimited access to all OpenAI models, including the full version of the o1 reasoning model.

Unlike other AI technologies, the o1 reasoning model will check its own work while doing it to avoid error-causing pitfalls.

However, it takes longer to come up with a solution. o1 reasons through tasks, plans, and executes a series of actions that help the model find the answer.

OpenAI released a preview of o1 in September, but this version is more efficient, faster, more powerful and more accurate, according to a spokesperson.

It's also been improved to reduce response times. According to internal testing, o1 reduced "major errors" on "difficult real -world questions" by 34% compared to the preview version.

All paid ChatGPT users can use o1 through the ChatGPT model selection tool. However, ChatGPT Pro subscribers will have access to a better version of o1, which does more calculations to produce “the best answers to the most difficult questions.”

At $200, ChatGPT Pro is currently OpenAI’s most expensive plan, 10 times more expensive than ChatGPT Plus. According to the New York Times , the startup plans to increase the price of ChatGPT Plus to $44/month by 2029.

ChatGPT remains one of the company's biggest revenue streams with over 300 million weekly active users and around 10 million paying users.

OpenAI kicked off its 12-day “shipmas” of new features, products, and demos. The company is expected to launch its Sora text-to -video tool and a new model.
