Wow. I saw 4.1B credits and thought it was super generous. But my math says the subscription plan gives less value than the API. For example, API input is $0.4

Wow. I saw 4.1B credits and thought it was super generous. But my math says the subscription plan gives less value than the API. For example, API input is $0.435 / M tokens, which works out to 13.79 M tokens for $6. Plan is 300 credits per input token, which works out to 13.67 M tokens at 4.1B credits per $6. Very similar math for cache input and output.
