$ / MU

Same jobs. What do you actually pay.

A cheap sticker can still be expensive. So can the harness. GPT in ChatGPT is not GPT in OpenCode. The index ranks stacks that finished every official task, on $ / MU. Incomplete runs are not cheap.

All stacks How we count

work-price.tswork-2026.08-py4

$ / MU    = $ billed / work MU
Work MU    = official job chars / 4
Rank       only if every task passed
               retries stay in $ billed

Cheapest to finish

Cheapest complete finish first. The full list and filters live on Stacks.

How they place

Complete finishes only, cheapest $ / MU first. Incomplete runs stay in the table.
