According to Epoch AI:

> The cost of achieving a given level of AI performance has fallen about 47% per quarter since 2023, or 13× per year. [0]

Then why are AI plans still so super expensive, and AI spending going through the roof, while all the subsidies are ending?

  • The cost per fixed level of intelligence is dropping, but we're also getting dramatically more intelligent models.

  • Reddit is full of people complaining how they burn their 200$ sub in half an hour by starting ten Max sub agents. That’s to say, many people just don’t know what they’re doing.

  • Because models are only getting better at a rate of 10% per year, people always want the best quality possible. You can get SotA performance from a year ago for a fraction of the cost, but why would you use Opus 4.5 when you can use Opus 5.5?

  • Because it's increasingly useful and the thing you are substituting (human time) is much more expensive.

  • Apart from what others said about using more intelligent models instead of cheaper ones, token usage is also increasing a lot. Classic Jevons paradox
