Prompt Caching ROI & Write Surcharge Break-Even Analysis
Prompt caching drastically reduces input token costs for static prefixes like system prompts, tool schemas, and document chunks. Compare caching mechanisms between Google: Gemini 4 Carbon and Anthropic: Claude Sonnet 5.5:
Google: Gemini 4 Carbon Caching Profile-95% read discount
- Cached Read Price: $0.100 per 1M tokens.
- Write Surcharge: $0.00 (automatic caching with zero write penalty).
- Minimum Cache Prefix: 1,024 tokens.
- Amortization Rule: Immediate net savings from first cached read call.
Anthropic: Claude Sonnet 5.5 Caching Profile-95% read discount
- Cached Read Price: $0.100 per 1M tokens.
- Write Surcharge: $2.50/1M (+25% fee on initial cache write).
- Minimum Cache Prefix: 1,024 tokens.
- Amortization Rule: Net cost savings begin when prefix is reused > 1.25 times within TTL.
Batch API 50% Discount Offload vs Real-Time SLA
Asynchronous Batch APIs cut total token expenditures in half (50% off input and output) in exchange for non-realtime execution (up to 24-hour turnaround SLA).
| Model / Architecture | Standard Input / Output | Batch 50% Off Input / Output | Turnaround SLA | Optimal Use Cases |
|---|---|---|---|---|
| Google: Gemini 4 Carbon | $2.00 / $10.00 | $1.00 / $5.00 (-50%) | 24 Hours max (typically 30m - 2h) | Bulk evaluation, dataset labeling, background summarization |
| Anthropic: Claude Sonnet 5.5 | $2.00 / $10.00 | $1.00 / $5.00 (-50%) | 24 Hours max (typically 30m - 2h) | Offline document translation, embedding backfills, test suites |
