Billing Transparency
ZenMux uses a transparent billing system to ensure every call is precisely metered and billed. Pricing differs across models, and the same model may be priced differently across providers.
Viewing Prices
You can view pricing for each provider on the model detail page. Every provider presents detailed billing standards, including costs for input tokens, output tokens, and special features.
For models with tiered pricing, rates are displayed by usage tiers to help you understand costs at different consumption levels.
Billing Items
ZenMux bills across the following item types:
| Billing Item | Description |
|---|---|
prompt | Cost for processing input prompts |
completion | Cost for model-generated output |
image | Cost for image processing or generation |
request | Base fee for API requests |
web_search | Cost for invoking web search functionality |
input_cache_read | Cost for cache read operations |
input_cache_write | Cost for cache write operations |
input_cache_write_5_min | Cost for 5-minute cache write operations |
input_cache_write_1_h | Cost for 1-hour cache write operations |
internal_reasoning | Cost for internal reasoning computations |
