OpenAI is creating a new, more expensive tier for its flagship chatbot ChatGPT and bringing its Reasoning model line out of preview with an update.

The company is releasing the full version of its o1 model (instead of o1-preview), which was originally released in September as a limited preview (codenamed “Strawberry”). The new model will be available to ChatGPT Plus and Teams users today, while Enterprise and Edu users will have access to it starting next week.

The company is also introducing ChatGPT Pro, a new $200 per month subscription tier that includes unlimited access to OpenAI o1, GPT-4o, and Advanced Voice mode. It also includes a version of o1, exclusive to Pro users, that requires more processing power to provide the best possible answer to the most difficult problems (called o1 Pro mode). The company continues to offer a Plus tier for $20 per month, which includes early access to new features, access to all of the company’s models (except the more powerful o1 version), and more.

The edge previously reported on the startup’s plans to launch a 12-day “ship phase” of new features, products and demos, with announcements including OpenAI’s long-awaited text-to-video AI tool Sora and a new model.

The company said that compared to o1-preview, users can expect a faster, more powerful and more accurate model that is better at coding and math. It can also provide “reasonable” answers to images. And OpenAI promises that it has been trained more concisely, which should result in faster response times than o1-preview.

OpenAI plans to add support for web browsing, file uploads, and more to ChatGPT – but there is no timeline for these changes.

A ChatGPT Pro grant program was also announced, awarding 10 ChatGPT Pro grants to medical researchers at leading institutions, with additional grants planned in various disciplines.
