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 Qwen: Qwen3.7 Max and ByteDance Seed: Seed 2.1 Turbo:
Qwen: Qwen3.7 Max Caching Profile-80% read discount
- Cached Read Price: $0.295 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.
ByteDance Seed: Seed 2.1 Turbo Caching Profile-60% read discount
- Cached Read Price: $0.200 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 |
|---|---|---|---|---|
| Qwen: Qwen3.7 Max | $1.48 / $4.42 | $0.74 / $2.21 (-50%) | 24 Hours max (typically 30m - 2h) | Bulk evaluation, dataset labeling, background summarization |
| ByteDance Seed: Seed 2.1 Turbo | $0.50 / $2.50 | Standard on-demand rate | Instant real-time | Offline document translation, embedding backfills, test suites |
