- 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 |
|---|---|---|---|---|
| OpenAI: GPT-6 Astra | $10.00 / $50.00 | $5.00 / $25.00 (-50%) | 24 Hours max (typically 30m - 2h) | Bulk evaluation, dataset labeling, background summarization |
| Mixtral 8x7B (32768) | $0.24 / $0.24 | $0.12 / $0.12 (-50%) | 24 Hours max (typically 30m - 2h) | Offline document translation, embedding backfills, test suites |
