In this video, we will take an in-depth look at OpenAI's latest release, the O1 model. As an upgraded version of GPT-4O, this model boasts enhanced reasoning capabilities, particularly excelling in complex fields like science, programming, and biology. Compared to previous models, O1 is not only more accurate but also able to showcase its thought process, helping users understand how it arrives at its answers. Although its response time is slightly slower, this delay results in more well-considered answers. We'll also discuss improvements in O1's safety features, usage limitations, and whether it's worth purchasing.
