Compare complete workflows on representative tasks, including the time someone spends fixing the output.
Start with the work, not the leaderboard
The best model for your team is the one that performs well on the work you need to do, within the constraints you can live with. A general benchmark can help you discover candidates. It cannot tell you how much correction your particular documents, codebase, or production process will need.
Write down three recurring jobs before comparing providers. For example: draft a support reply from a policy pack, repair a small bug, and turn a set of meeting notes into a checked action list. These jobs require different kinds of accuracy and different kinds of review.
If one candidate wins one job and loses another, that is a useful result. You do not need to force every task through the same model simply to make procurement or a slide deck look tidy.
Define an acceptable answer
Acceptance should describe what someone can actually use. For a support reply, it might require the right policy, no invented promise, a clear next step, and an appropriate tone. For code, it might require the intended behavior, relevant checks, and no unrelated changes.
Separate hard requirements from preferences. A wrong refund promise should not be averaged away by a friendly tone. A broken export should not pass because the preview looks good. Mark critical failures directly, then score the qualities that can reasonably vary.
Write the criteria before looking at the outputs. Otherwise it is easy to reward the behavior of the model you already like. When practical, have someone review outputs without knowing which candidate produced them.
Make a small task pack
Choose representative examples, including ordinary work and a few difficult cases. Add at least one incomplete brief, one conflicting source, and one case where the correct response is to ask for more information or say the answer is unavailable.
Use sanitized material that you are permitted to send to the selected service. Preserve the structure of the job without including customer information that is unnecessary for the test. Keep a separate answer key or review rubric so the candidate does not receive the answer it is supposed to produce.
A small pack is a pilot, not a population estimate. It can reveal obvious problems and help you choose what to test next. If the decision affects a large workflow, expand the sample and review the uncertainty before making a broad rollout decision.
Compare like with like
Record the exact model, product, date, settings, tools, prompt, and source material. A model inside a coding agent with a terminal is not the same tested system as a chat window with no tools. You can compare the workflows, but describe them accurately.
Give each candidate a comparable opportunity to finish. Set a time limit, retry allowance, and tool budget. Count the unsuccessful attempts. If you let one system try five times and give another one attempt, the result includes that policy difference.
Keep useful changes to the prompt versioned. It is reasonable to improve a weak brief during development. Once you are comparing candidates, rerun the relevant tasks under the same revised conditions rather than giving only the favored model the better instructions.
Measure the work around the answer
Record direct service cost, time to a usable output, reviewer time, and the number of accepted results. Note any work the system pushes onto another person, such as cleaning a file, finding a missing citation, or correcting an unsupported claim.
| Measure | What it helps you understand |
|---|---|
| Accepted results | How often the output met the agreed requirements |
| Critical failures | Problems that cannot be traded for style or speed |
| Review minutes | The human effort needed to check and repair the work |
| Total service cost | Charges across all attempts, including retries |
| Completion time | Whether the workflow fits the deadline |
Avoid compressing everything into a single unexplained score. A team may accept slower completion for better accuracy, or pay more to reduce review work. Keep the components visible so the decision reflects those priorities.
Make a limited adoption decision
Choose a first use with a clear owner and a way to return to the previous workflow. Perhaps the model can draft internal summaries with review. Perhaps it can propose code changes in a branch. Do not automatically extend a good result on one task into permission to take unrelated external actions.
After adoption, keep a few stable checks and add important real failures to the task pack. Revisit the comparison when the model, prompt, tools, or source material changes materially. You need enough monitoring to notice a meaningful regression, not an elaborate ceremony around every small edit.
The model-comparison worksheet lets you compare acceptance, cost, and review effort using your own numbers. It does not call a model or manufacture a benchmark. Its job is to keep the arithmetic honest while you do the harder work of deciding what counts as a useful result.
