If the model is as good as the benchmarks say, the pricing is fantastic: Input: $1.25 / 1M tokens (cached: $0.125/1Mtok) Output: $10 / 1M tokens For context, Claude Opus 4.1 is $15 / 1M for input tokens and $75/1M for output tokens. The big question remains: how well does it handle tools? (i.e. compared to Claude Code) Initial demos look good, but it performs worse than o3 on Tau2-bench airline, so the jury is still out.

> Output: $10 / 1M tokens It's interesting that they're using flat token pricing for a "model" that is explicitly made of (at least) two underlying models, one with much lower compute costs than the other; and with use ability to at least influence (via prompt) if not choose which model is being used. I have to assume this pricing model is based on a predicted split between how often the underlying models get used; I wonder if that will hold up, if users will instead try to rouse the better model into action more than expected, or if the pricing is so padded that it doesn't matter.

      In the API, there’s no router. Developers just pick whether they use the reasoning model or non-thinking ChatGPT model.

  That's how the browser-based ChatGPT works, but not the API.

It does seem to be doing well compared to Opus 4.1 in my testing the last few hours. I've been on the Claude Code 200 plan for a few months and I've been really frustrated with it's output as of late. GPT-5 seems to be a step forward so far.

Price is not the same as cost, and that price may get jacked up without much warning. The price is what it is today because they are trying to become a dominant platform. It doesn't mean the price reflects what it actually costs to run. I'd bet a lot of the $40 billion they got in March goes towards loss leaders.
