What is strange about GPT-4 being expensive in 2023? Supply and demand. Which other model choices did we have? Prices are related to supply and demand. We see it play out with the introduction of capable open weight models or even other closed cloud models.

That’s a slightly naive view on pricing. That equilibrium point doesn’t just magically appear - it’s found through price testing.

Not really though right?

As of early June 2026, Opus 4.8 in fast mode cost $50/M output tokens and Opus 4.6 & 4.7 cost $150/M output tokens in fast mode

How can supply and demand explain the price drop? Was it cheaper to serve Opus 4.8? Is the demand for the newer Opus lower than for the older Opus? These are just fixed prices that seem picked out of thin air

		They would have been picked out of thin air. That’s the joy of innovation - you have to randomly throw prices against the wall and see what sticks. The point where it sticks might be equilibrium or it may be an inefficient market… and nobody will know which one until it’s too late.
