Start with the artifact you need tomorrow
Write a sentence with an inspectable ending: “I need a reviewed pull request,” “I need three design directions I can revise,” or “I need a mobile page that works after login.” Do not start with the question of which model is smartest. If you need editable design layers, an excellent image is still the wrong handoff. If you need a working website, a beautiful Figma file is an intermediate result. Put that sentence at the top of your comparison and reject options that cannot deliver the required format.
Use this short decision tree
Already have a subscription that can reach your files and tools? Try it first on a small copy of the task. Cannot access the needed tool or export? Compare products and integrations before comparing models. Can produce the format but repeatedly misses an important requirement? Run the same bounded task with one alternative. Both succeed? Compare correction work and the cost of completing the task. Neither succeeds? Break the task down or change the workflow; another expensive subscription is not automatically the answer.
Compare five costs—not one monthly number
Record the subscription fee, any metered API usage, additional software or assets, human correction time, and the consequence of a wrong result. A plan’s included allowance is different from unlimited work. For example, GitHub documents distinct plan capabilities and usage arrangements; check the relevant provider’s current plan page rather than copying a price from a social post. Use a dated note for official facts, and label your own usage estimate separately.
Supporting documentation (opens in a new tab)A worked example: one editable product page
Suppose you need a landing page with a working form. The experiment is not “make a beautiful website.” Give each candidate the same text, reference and success condition: the form accepts valid input, explains invalid input, preserves the draft after an error, and fits a narrow screen. Keep the first output and count meaningful corrections. If one output looks better but its form never submits, it has not finished the same job. If both require a service you have not configured, record that dependency rather than attributing the missing capability to the model.
Leave with a decision you can reverse
Fill five lines: my task; the toolchain tried; the artifact I inspected; the reason to keep or reject it; the next event that would make me reconsider. That event could be a new task, an actual limit you hit, or a feature becoming available—not every launch headline. Set your own time and additional-spend ceiling before the experiment. This is our decision method, not a promise of savings or a verified recommendation for every plan. For the current interface and plan rules, return to official documentation before paying.
