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 DeepSeek: DeepSeek V3.2 and Google: Gemini 4 Hydrogen:
DeepSeek: DeepSeek V3.2 Caching Profile-50% read discount
- Cached Read Price: $0.130 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.
Google: Gemini 4 Hydrogen Caching Profile-95% read discount
- Cached Read Price: $0.075 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.
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 |
|---|---|---|---|---|
| DeepSeek: DeepSeek V3.2 | $0.26 / $0.38 | Standard on-demand rate | Instant real-time | Bulk evaluation, dataset labeling, background summarization |
| Google: Gemini 4 Hydrogen | $1.50 / $7.50 | $0.75 / $3.75 (-50%) | 24 Hours max (typically 30m - 2h) | Offline document translation, embedding backfills, test suites |
