Is it a larger model or just better trained? Anthropic does not actually claim it is a larger model anywhere that I can see.

If it’s not larger, it’d be tough to justify the massive price increase for using it.

Price is based on perceived value, not cost to produce. There is no international court of price justifications; if customers are willing to pay $X you can charge $X.

That and a model can be the same size, yet use a lot more compute, I guess think of it as intelligence per watt used or something like that.

[brookst]

Exactly. The company should care because it drives margins. But pricing to customers should not change unless it was artificially high (competitors offer more value for same money) due to profitability concerns.

Opus 4.7 was smaller and people still paid 4.6 prices.

gpt-5.5 isn't larger than gpt-5.4 but costs double.
