For a while, if you asked the iPhone version what it was it claimed to be GPT3.0. Not sure if it still is that, but I noticed the iPhone version was a bit worse. Maybe they rolled that out more broadly?
GPT-3 lineage model quality drastically declined over time from the initial launch of each too, with no transparency offered or critical feedback acknowledged by the lobotomy teams. It’s a shame to see it happening again and again.
