Our summary
A program may have several tools or AI services available for a request. This guide explains choosing which should handle the work. Some tasks need exact rules, some fit a smaller model, and others need more reasoning. A separate check may block a request before any action.
First remove services that cannot meet fixed requirements. A picture needs a service that can inspect images; a long document needs enough room for its text. Jev can then judge the fit among remaining options without being asked to decide those exact capability limits.
Choosing a service adds its own chance of error, waiting time, and cost. Suggested cutoffs are starting advice, not universal settings. Test the final answer quality, use of backup routes, total cost, and total delay on realistic requests before assuming the extra step helps.
Key takeaways
- First remove options that cannot handle a required image, document length, or other fixed need.
- Send blocked or uncertain requests to a stated fallback, such as a person or safer service.
- Measure final quality, the number sent to fallbacks, total cost, and delay; the suggested ranges are unverified guidance.
