In my opinion, Openai is much better, and during training, just yesterday I watched an article about how the developers are already thinking about its limitations, and especially because Openai can already create projects and think on its own. https://www.designbolts.com/2018/07/06/best-free-tri-fold-3-panel-brochure-mockup-psd-presentations/ It’s probably unlikely that someone will outdo it, I even saw how it itself creates 3D models of great quality
OpenAI and Azure depends on your specific needs. OpenAI is a research organization that develops AI models like GPT-3, while Azure is a cloud computing platform by Microsoft that offers various AI services, including the deployment of models like GPT-3.
I like OpenAI it's easy to use for me, I'm able to do just about anything I need to, Uve not tried Azure yet, so really this maybe not a fair review, but it probably wouldn't be anyway cause I'm an AI person.
if you mean using Open AI on Azure or Open AI directly - i've chosen to use the version on Azure. It is slower to take on new features from the Open AI models but I have found it more stable in handling my traffic
