Dev Rants About Cache Write Billing
Yankzy · reddit · 2026-07-11
The poster complains about the new cache write billing model. Since they work on one-off inference tasks like document processing, classification, and information extraction, they rarely reuse prompts, making cache writes useless to them.
Main points of contention:
- Cache writes incur extra fees, sometimes even higher than the input cost itself.
- Developers want an explicit toggle to decide whether to force cache writes.
- The author feels this complex billing makes API costs harder to explain to clients, stating it's a key reason they avoid using the Anthropic API.
