OpenAI Rolls Out ChatGPT Pro with Unlimited Access: Subscription Details Inside

New Delhi (The Uttam Hindu): OpenAI has launched **ChatGPT Pro**, a new subscription-based service offering unlimited access to **GPT-4**, **OpenAI o1**, and **Advanced Voice Mode**. Priced at $200 (approximately ₹17,000) per month, ChatGPT Pro also includes the exclusive **o1 Pro Mode**, which delivers superior solutions to complex problems by utilizing enhanced computing power and advanced reasoning capabilities.

In addition to ChatGPT Pro, OpenAI has retained its existing **Plus Tier**, which costs $20 (roughly ₹1,700) per month. The Plus Tier provides access to all models, early access to new features, and other benefits, but it does not include the advanced **o1 Pro Mode**.

The company has also officially ended the preview of the **OpenAI o1 model**. The new full version of the **o1 model** replaces the earlier **o1-preview** version, which was launched as a limited preview in September under the code name "Strawberry." The upgraded o1 model is now available to ChatGPT Plus and Team users, while **Enterprise** and **Edu users** will gain access next week.
