For the amount of tokens you get, based on your comment, ALL subscriptions are heavily subsidized, and the most expensive ones are the most subsidized.
For OpenAI and Anthropic, the $100 subscriptions cost 5x the $20 subscriptions and give you 5x the tokens. And the $200 subscriptions are 10x the cost for 20x the tokens. (Tokens cost 50% as much.)
