Not So Fast AI routes requests down the model ladder

Field notes

For missions, a lead model writes a short spec with 2–6 acceptance criteria, divides work into subtasks, checks each answer, and allows one repair pass. Tool-calling requests skip the local tier; the page says out-of-credit or forbidden-key providers are paused for 30 minutes, while repeated 5xx errors trigger backoff. The site reports ledger-based cost results, but the comparison is not independently verified here.
