On: I gave Opus 5.5 one prompt and six hours to visualize Invisible Cities

One useful hint here is the API token cost - in this case "about $74 in API tokens" for Opus 5.5.

We know Anthropic run inference at a margin, so that $74 means that the cost of the electricity involved is substantially less than $74. I'd love to know the actual cost there.

I wonder how you only reach $74 in 6 hour runtime. I would have guessed this runtime goes into the hundreds of dollars.

Or I'm realizing that I'm overpaying my tokens...

A lot of that 6 hours isn't spent waiting for the models to return tokens, it's spent executing the code that they've written.
