Commitment to quality

The upgrade process focused on our unwavering commitment to quality, safety, and security. Here’s what that entailed:

1. Offline and online evaluation: We performed rigorous offline and online testing to ensure the model brings tangible benefits to users. This involved thorough benchmarking and running simulations of real-world software development scenarios to validate the improved performance and accuracy of GPT-4o.
2. Red teaming: To preemptively address any potential safety issues, we conducted extensive red teaming exercises. These tests challenged the model to ensure it meets our high standards for safety and reliability in diverse coding environments.

We can’t wait to see what you create with the new GPT-4o-powered Copilot!
