In February, we launched the research preview of GPT-4.5, which is more intuitive and collaborative than previous models, making collaboration significantly easier.

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.

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.

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.

We focused on alignment and safety for GPT-4, aiming to gather feedback from researchers to enhance its reliability and robustness.

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.

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.

GPT-4.5 is potentially more than 10 times the size of GPT-4, representing a step forward in both pre-training and post-training processes.
