Overview
CoreWeave AI Object Storage Usage-Based Billing introduces a third tier of storage pricing for AI Object Storage: Hot, Warm, and Cold. Usage-Based Billing replaces the previous Automated Archive feature, and is enabled by default starting October 31, 2025.
Data billed as Cold has the same performance as Hot or Warm data. This feature is enabled by default starting October 31, 2025.
How it works
When objects are evaluated during hourly billing cycles, they are classified as Hot, Warm, or Cold based on when they were last accessed:
| Pricing Tier | Description |
|---|---|
| Hot | Objects that are newly uploaded or accessed within the last 7 days. |
| Warm | Objects that are accessed within the last 7 to 30 days. |
| Cold | Objects that haven't been accessed for 30+ days. Specifically, an object is considered Cold if no bytes of the object have been read in the trailing 30 days at the time it is measured for hourly billing. |
What counts as object access
During hourly billing cycles, the last access time is measured. The following actions reset the timer and bring objects back to the Hot tier:
| Action | API Method | Description |
|---|---|---|
| Upload | PutObject, UploadPart | When the object is first uploaded |
| Read | GetObject | When the object is downloaded or accessed |
| Copy | CopyObject, UploadPartCopy | When the object is copied (both source and destination are considered "accessed") |
