OpenAIs ChatGPT Pro Subscribers to Get Enhanced o3 Pro Model, Replacing Legacy o1 Pro

The folks at OpenAI have decided to stoke the flames of their most expensive subscription — **ChatGPT Pro for $200 a month**. As you might know, this premium tier already provides access to a variety of models, including o4-mini, o4-mini-high, GPT-4.5, GPT-4.1, GPT-4.1-mini, and even o3 (which regular Plus subscribers at $20 also have access to). However, the standout feature of Pro was the **o1 Pro** model — the one given **more computational resources** to «think harder» on particularly challenging tasks.

However, times are changing. While o1 Pro is powerful, it has started to seem a bit **dated** compared to the newer and generally smarter o3. But it seems that this discrepancy will soon be a thing of the past.

As hinted at the [event in New Delhi](https://x.com/btibor91/status/1930587164271661512), OpenAI is preparing an update: **o1 Pro will be replaced in the Pro subscription by o3 Pro.** This means that users willing to pay $200 will gain even more power for tackling truly complex problems.

Let’s break it down. The basic o3 already outperforms o1 in most benchmarks. But the unique aspect of o1 Pro was its allocation of more «computational brains,» making it more reliable on particularly tough challenges — like the most complex math contests, hardcore coding challenges, or scientific questions at the PhD level. It **thinks slower, but smarter** under such demanding conditions.

The new **o3 Pro** is expected to combine the best of both worlds: the advanced foundational reasoning of o3 with enhanced reliability thanks to additional resources, similar to o1 Pro. Essentially, it’s an upgrade of the existing o3 — its cognitive abilities will be enhanced, allowing Pro users to achieve more.

The announcement for o3 Pro for lucky holders of the $200 subscription could come as soon as next week or by the end of the month. Stay tuned for updates!

Another significant aspect of the update will be the substantial expansion of features for the **ChatGPT Connectors**. This tool allows your ChatGPT to connect with external services like Google Drive and Slack, giving it access to your files and data directly within the conversation. Now, the list of integrations will include **Dropbox and Box**.

However, the most exciting feature is the opening of doors for **custom integrations** through the Model Context Protocol (MCP). In simple terms, MCP is your ticket to creating **your own gateways**. Want ChatGPT to interact with your internal knowledge base, specific CRM, or niche API? You got it. You define your endpoints, and the AI can access them.
