I settled on GPT Plus/Codex for my own work, while my employer settled on Claude on Bedrock (where I am, according to their metrics, using about $20 of compute a day, so I can believe that GPT Plus is a loss-leader). If I hit too many 5-hour timeouts I'm not jumping to Pro I'm jumping to Claude.
(Funnily enough, I just hit one. It'll reset in... three hours. I wasn't even hammering it, just writing some tests. I think I'm gonna just go reactivate my Anthropic account for a month).
Those who benefit from using and LLM will continue to pay for one, regardless of provider, regardless of the price being $20 or $50.
The global aspect is interesting, because $50 is a lot of money for most of the global population. The AI advocates claim to be getting more hundreds, if not thousands, of dollars of value from their subscription. In the poorest countries that should make an even greater difference, but that assumes that they can get those first $50 and that the value is actually being generated.
For ChatGPT I really only see two customer groups, pro-consumer and small and medium enterprise. The entry level are just going to use Google/Gemini for the most part, or some ad supported ChatGPT tier. There's no price low enough to make the entry level, average consumer pay for an AI service. These are people who will not pay for search, email and social media. They only pay for streaming because there's no way around it.
