Offloading multiple-choice decisions to Jev to cut Opus 5.5 costs
Short multiple-choice decisions like which notes to load, whether to retry, and which tests to run first go to the cheaper Jev model, while Opus 5.5 keeps planning, coding, and debugging.
YOUR CODING AGENT IS PAYING OPUS 5.5 PRICES FOR MULTIPLE CHOICE QUESTIONS... which notes to load big model or small one retry or give up which tests to run first each one has a short list of answers you do not need Opus 5.5 for them so Opus keeps the planning, the code, the debugging a cheap model called Jev picks from the list your code decides when it is sure enough, and when it is not the step goes back to Opus the agent loads only the notes it needs, stops looping on retries, runs the tests that matter first Opus works only on the steps that need it
