A realistic example
Customer Support costs $9,578 a month. What should replace GPT-6.1 Sol?
Price alone cannot answer that question. Compare Mode runs a controlled evaluation against the same support workload and keeps the production model unchanged.

Illustrative results for one workload. Actual outcomes depend on your prompts, providers and quality criteria.
Why the winner is not simply the cheapest
Mistral scores slightly higher. Gemini wins overall.
Gemini clears the quality threshold while delivering the lowest projected cost, fastest response and strongest reliability. Compare Mode makes that trade-off visible instead of hiding it behind one benchmark score.

Your customer conversations are not the test data.
Candidate calls run in your staging application with provider keys you control. Optional hosted quality evaluation uses a redacted prompt template and safe generated examples. Dynamic customer values and production responses stay private.
Choose a model with evidence from your workload.
Find the workload worth testing, compare three practical alternatives and validate the winner before changing production.
