FAQ
How is monthly cost calculated?
For token APIs, monthly cost is input tokens times input price plus output tokens times output price. For TTS, it uses monthly characters. Vector database estimates depend more heavily on storage and read/write usage.
Why are some models excluded?
The calculator excludes models that do not satisfy required context window, requests per minute, streaming, JSON mode, or tool calling constraints.
Are these prices guaranteed?
No. The dataset is designed for comparison and should be checked against official pricing pages before production decisions.
