Model selection is shifting from token price to the cost of a correct outcome

AWS has published a benchmarking approach that compares OpenAI models by task success, token use and multi-turn behavior instead of headline token price alone.

What changed?

The AWS analysis argues that production teams buy completed outcomes: a resolved request, an accurate summary or a finished research task. A cheaper token rate can lose its advantage when a model needs more tokens, more retries or more conversation turns to reach an acceptable answer.

Its open-source harness evaluates several OpenAI models available through Amazon Bedrock and the OpenAI API. The practical lesson is to benchmark with representative prompts, quality thresholds and the full workflow cost rather than choosing from a pricing table in isolation.

What should you keep in mind?

Published benchmark results remain workload-specific. Latency, regional availability, data controls and the cost of human review can materially change the decision for another organization.
