Update to GPT-4o (September 3, 2024)

Today, we've updated GPT-4o in ChatGPT. This version is better at incorporating uploaded files and updating memory with key parts of a conversation to make future interactions more helpful and relevant.

Update to GPT-4o (August 12, 2024)

"Bug fixes and performance improvements” … we’ve introduced an update to GPT-4o that we’ve found, through experiment results and qualitative feedback, ChatGPT users tend to prefer. It’s not a new frontier-class model. Although we’d like to tell you exactly how the model responses are different, figuring out how to granularly benchmark and communicate model behavior improvements is an ongoing area of research in itself (which we’re working on!).

Sometimes we can point to new capabilities and specific improvements — and we'll try our best to communicate that whenever possible. In the meantime, our team is constantly iterating on the model by adding good data, removing bad data, and experimenting with new research methods based on user feedback, offline evaluations, and more. That's the case with this model update.

We’ll continue to keep you posted as best as we can. Thank you for your patience!

Introducing GPT-4o mini (July 18, 2024)

We’re introducing GPT-4o mini, the most capable and cost-efficient small model available today. GPT-4o mini surpasses GPT-3.5 Turbo and other small models on academic benchmarks across both textual intelligence and multimodal reasoning and supports the same range of languages as GPT-4o. It also demonstrates strong performance in function calling, which can enable developers to build applications that fetch data or take actions with external systems, and improved long-context performance compared to GPT-3.5 Turbo.

You can read more about GPT-4o mini in the blog announcement.
