OpenAI’s ChatGPT 4.5 release has officially arrived. On Thursday, the innovative team behind ChatGPT unveiled the latest version of their large language model (LLM) in a research preview. As OpenAI’s CEO Sam Altman mentioned a few weeks ago, GPT-4.5 is the final model from OpenAI that won’t utilize a chain-of-thought reasoning approach. This indicates that future models will incorporate enhanced reasoning capabilities.

What Sets ChatGPT 4.5 Apart?
According to the latest white paper, early testing reveals that users interacting with ChatGPT 4.5 experience a more natural conversation flow. The model’s wider knowledge base, improved alignment with user intent, and heightened emotional intelligence make it especially adept at various tasks such as writing, coding, and addressing practical challenges—all while significantly reducing instances of misinformation or “hallucinations”.
Understanding the Capabilities of ChatGPT 4.5
During the demonstration, OpenAI team members clarified that GPT-4.5, while not a dedicated reasoning model, possesses advanced knowledge. Although primarily designed as a general-purpose tool, it can effectively tackle reasoning tasks, distinguishing itself from the earlier series that excelled in fields like science and mathematics. The ChatGPT 4.5 release marks the newest iteration in the GPT series since GPT-4o was introduced last May.
The Road to GPT-5
The launch of GPT-4.5 comes with its own narrative, as it highlights the delays surrounding the much-anticipated GPT-5. Ongoing reports suggest that OpenAI may be facing diminishing returns on model advancements, implying that merely scaling up compute and datasets does not necessarily translate to better performance outcomes. This could explain the delayed GPT-5, which Altman has predicted will offer intelligence surpassing even the highest expectations. Former CTO Mira Murati has stated it will embody ‘Ph.D.-level intelligence.’ Meanwhile, GPT-4.5 serves as a significant milestone in this journey, suggesting either upcoming high performance or potential setbacks.
How to Access GPT-4.5
If you are eager to try GPT-4.5, there are steps you must take. Currently, GPT-4.5 is available exclusively to ChatGPT Pro subscribers, who contribute $200 per month. ChatGPT Plus users, who pay $20 monthly, will gain access next week. Although this is only a week’s wait, many Plus subscribers might feel frustrated, as they once enjoyed priority access for new feature rollouts. OpenAI is likely targeting an increase in Pro subscribers with this release, but it risks alienating Plus users, especially with competitors like xAI’s Grok 3 and Anthropic’s Claude 3.7 Sonnet rapidly catching up.
As we embark on using ChatGPT 4.5, much is at stake: will it meet the lofty expectations set for GPT-5’s development, or will it signal further delays? The forthcoming months will undoubtedly provide clarity.
