Start with usage rather than a subscription label
An AI feature’s cost depends on how people use it and which services it calls. Estimate requests per day, average input size and expected response length. Include busy periods and repeated attempts. A website with a small audience can still generate substantial usage if each visitor triggers a long, multi-step process.
Build a simple cost worksheet
Create rows for model calls, retrieval or storage services, hosting, monitoring and human review. Record the unit price from the provider’s current pricing page and the assumed usage beside it. Keep assumptions visible. The worksheet should be easy to update when a model, feature or usage pattern changes.
Count retries and supporting work
A successful result may require more than one call. Include validation failures, planned retries and background tasks in the estimate. Also count the staff time needed to check results. The relevant comparison is the cost per useful completed task, not just the price of one generated response.
Add practical controls
Limit input length and output size where appropriate. Decide which users may access the feature and how much usage is allowed. Monitor consumption and configure alerts, while checking whether each provider setting is an alert or an actual enforced limit. Do not assume a budget notification automatically stops charges.
Review real data after a pilot
Compare estimated and actual usage for a small release. Find the tasks that consume the most resources and whether their results justify the cost. Improve prompts, reduce unnecessary context or simplify the workflow before expanding access. Use current provider prices when making a commercial commitment; this guide intentionally does not quote a model tariff.
