Assumptions
- Side project: 800 input and 300 output tokens per request at 1,000, 10,000, and 100,000 requests per month.
- Customer support chatbot: 6 replies per conversation, 600 system tokens, 90 user-message tokens, 1,000 retrieved-context tokens, 180 output tokens per reply, and 50% history carry, for 10,000 conversations.
- Agent task: 8 model calls per task, 1,500 input and 400 output tokens per call, for 1,000 tasks.
- Standard rows use non-cached, non-batch prices. A Batch row appears only when both published Batch token prices exist.
