| Scenario | Cost | Assumption |
|---|---|---|
RAG answer per 1,000 RAG answers | $29.75 $0.03 per request | 5K input tokens (query + 4 retrieved chunks of ~1K each) and a 500-token answer. Typical SaaS knowledge-base bot. |
Support ticket triage per 10,000 tickets | $59.50 < $0.01 per request | 1K input tokens (ticket body + system prompt) and a 100-token JSON classification reply. High-volume customer support. |
Data extraction per 1,000 documents | $17.00 $0.02 per request | 2K input tokens (a single document page) and a 500-token JSON extraction. ETL / invoice / form pipelines. |
Code review per 1,000 PRs | $51.00 $0.05 per request | 8K input tokens (diff + surrounding files) and a 1K-token review comment. PR-bot workloads. |
Agent step per 1,000 steps | $61.20 $0.06 per request | 12K input tokens (long-running tool history) and a 600-token tool-call decision. Cost per agent step. |
