> 8x increase over gpt-5.3-codex
How do you arrive at that number? I find it hard to make sense of this ad hoc, given that the total token cost is not very interesting; it's token efficiency we care about.

which is basically maxxed out quickly. So there is 2x (the first lever)
Then there is the /fast mode, which they state costs 2x more (for 1.5x speedup)
And then there is the model base price ($2.50 vs $1.75), well yeah thats 42% increase. It is in fact a 5.7x total increase of token cost in fast mode and large context. (Sorry for the confusion, I thought it was 8x because I thought gpt-5.3-codex was $1.25)
