We integrated some of the improvements from GPT-4.5 into our mainline GPT-4 model to enhance its collaborative capabilities.

When we launched GPT-4.5, we were proud of the model, but users liked it much more than we anticipated, expressing that it was significantly better than GPT-4 in various ways.

It's important to understand why these improvements matter for your team, as they can significantly enhance collaborative efforts, and GPT-4o enables quicker adoption by teams without the need for special training, leading to higher productivity and improved collaboration.

GPT-4.5 is OpenAI's largest and most humanlike model to date, representing a significant step in scaling up unsupervised learning and achieving a deeper understanding of the world and human experience.

These enhancements allow GPT-4 to communicate more naturally, resembling the interaction with a real teammate, which is beneficial for team collaboration.

The collaboration between teams on model specifications for GPT-4.5 involved deep co-design efforts, focusing on optimizing functionality and ensuring the ML and systems work well together at scale.

Reactions to GPT-4.5 have been muted because its improvements over GPT-4 are seen as relatively incremental, despite this launch being an important milestone for future models.

During the months leading up to the public launch of GPT-4, our entire team was intensely focused, which allowed us to iterate quickly and stay ahead of the market.

The initial goal for GPT-4.5 was to create a model that is ten times smarter than GPT-4, which we ultimately achieved through a complex process.
