Don't worry, claude will follow soon enough. It's not like anthropic faces different financial pressures than openai.
What would be the price at which you would stop subscribing? Im in tech, so I would willing to pay around up to 100 - 120 USd per month, Id guess (Im currently onthe 20 USD plan, which is supercheap and contains enough tokens currently)
But most private users ("at home") would not pay 100 USD+ per month? Spotify is around ~ 240/250 USD per year
