Choose the model on your own work
Run the same representative tasks through the options you are considering. Compare answer quality, tool behavior, response time and total cost with the people who will use the result.
Compare the result
Use a test set from your own work. Score correct answers, source use, tool actions and the corrections reviewers need to make.
Compare the operating needs
Check the required features, data handling, region availability, service terms and failure behavior in the current provider documentation.
Make the choice with evidence
Record model versions, prompts, test cases and costs. Revisit the comparison when the task or provider options change.
