Asana's browser tests show why the workflow matters as much as the model
OpenAI and Asana describe a 144-run study of a browser agent gathering book information from a demo catalog. Better history caching and screenshot handling lowered estimated model cost on the original model by 29 times; switching models brought the combined reduction to 76 times, averaging $0.47 per run. This is a narrow company-run experiment, not a guarantee of savings on other tasks or a measure of total operating cost.

Before buying a bigger model, measure where an agent resends unchanged information. Compare completed tasks, errors, review time and total cost on the same workload; keep spending and step limits in place.
