Do the math on 1,000 coding tasks a month. Opus 5.5 doing everything: $6,420 Jev + Opus 5.5: $2,000 That's $4,420 a month back. $53,040 a year. Same tasks. Same model writing the code. The only difference is who makes the small decisions. Full build below. Bookmark this.

@cyrilXBT another twist: watch out for context switching. It can eat up that $53k in mental load, even with optimized tools.

Anthropic lists Opus 5.5 at $4 input, $20 output, $0.20 cache read and $5 cache write per million tokens. The $6,420 line does not say which of those rates it used.

Same model, same coding tasks, lower costs.

Routing layer changes the math entirely

The number that matters is the miss rate. If Jev gets even 1 in 20 of those small calls wrong and Opus has to redo the work, a chunk of that $4,420 goes back. Put the rework rate next to the cost chart and this gets a lot more convincing.

Hi

$4,420 a month back just from moving the small decisions off opus 5.5 is the part people miss. most of the bill is the model thinking about stuff that didn't need thinking. curious how often jev picks wrong and opus 5.5 has to clean it up, that's where the real savings get decided.

everyone's bookmarking the savings and nobody's budgeting for the tuesday where jev confiddntly ships the wrong thing

letting a cheaper model handle the small calls and opus only write the code is the move fr curious how often the small decisions end up wrong and cost the savings back tho

省钱才是硬道理 小决策里藏着大金矿

Love seeing this

everyone bookmarking this and nobody asking who's checking Jev's work at 3am

the small decisions are where the real money hides tbh

grabbed this warm-up round shows footwork worth trying alone
