Thanks for asking! I haven't tested it long enough in a real business workflow to give you a solid personal verdict yet. That part of the article was based on OpenAI's published information rather than my own long-term testing. I'm planning to spend more time with it though, especially comparing cost, speed and output quality. If I find anything interesting, I'll probably write a follow-up about the actual experience.
