OpenAI announces full “o1” reasoning model, $200 ChatGPT Pro tier

On Thursday during a live demo as part of its “12 days of OpenAI” event, OpenAI announced a new tier of ChatGPT with higher usage limits for $200 a month and the full version of “o1,” the full version of a so-called reasoning model the company debuted in September.

Unlike o1-preview, o1 can now process images as well as text (similar to GPT-4o), and it is reportedly much faster than o1-preview. In a demo question about a Roman emperor, o1 took 14 seconds for an answer, and 1 preview took 33 seconds. According to OpenAI, o1 makes major mistakes 34 percent less often than o1-preview, while “thinking” 50 percent faster. The model will also reportedly become even faster once deployment is finished transitioning the GPUs to the new model.

Whether the new ChatGPT Pro subscription will be worth the $200 a month fee isn’t yet fully clear, but the company specified that users will have access to an even more capable version of o1 called “o1 Pro Mode” that will do even deeper reasoning searches and provide “more thinking power for more difficult problems” before answering.

Today, we’re adding ChatGPT Pro, a $200 monthly plan that enables scaled access to the best of OpenAI’s models and tools. This plan includes unlimited access to our smartest model, OpenAI o1, as well as to o1-mini, GPT-4o, and Advanced Voice. It also includes o1 pro mode, a version of o1 that uses more compute to think harder and provide even better answers to the hardest problems. In the future, we expect to add more powerful, compute-intensive productivity features to this plan.

The new service seems aimed at those who might benefit from higher rate limits and more computational time devoted to coming up with an answer. “ChatGPT Pro provides a way for researchers, engineers, and other individuals who use research-grade intelligence daily to accelerate their productivity and be at the cutting edge of advancements in AI,” OpenAI writes in its press release.
