Browse stacks
Filter by use case, model, framework, cost basis, and how recent the writeup is. Cost is only filled in when the source states it — otherwise it's “Not stated.” Separately, a dashed “Est.” tag is a WhatWeRun estimate from public list prices, with its assumptions shown on the stack page. Writeups older than about six months are marked as an older setup, not hidden.
Cost per outputSome teams report what one finished piece of work costs (a code change, a request, an investigation) instead of token prices. We tag that only when the writeup states it, and label benchmark or eval figures. Show those stacks.
