Hi HN, I use sonnet 4.5 every day a lot like $2500 per month and it turned out that Opus 4.5 even better, much better and cheaper.It is unbelievable. How come? It spends less tokens, like it’s more smart to use less context.

Why aren't you on the max "unlimited" plan for $200/month? Even with the limits it has, you'd need 12.5 of those accounts to hit $2,500/month.

No way I would create such a realistic demo without it.

It doesn't have the right sproinginess feel, imo.

Sacrifices style over function in my opinion.
