It's a blend, just like McDonald big mac, 80% of real food, 20% of unknown xxx.I've had mixed results with chatgpt and Gemini. It had suggestions of what museums in BA were free on what days... 80 percent correct, maybe 20 percent fake news. But it was better than the alternative of looking them all up individually.
One time I used it to answer a question about some economic thing and it gave a correct answer, minus a zero on the end. Oops.
I'm not a fan and have a million reasons to roll my eyes when people cite it as an authority. Not the least of which: it's trained on copyright materials and competing directly against the people whose work was taken in the name of 'progress'. We will always want professional translators but we are going to snuff them out as a profession.
Certainly it has downgrades in every aspects recently.
