How much does Claude Opus 4.6 cost per million tokens?
Claude Opus 4.6 costs $5.00 per million input tokens and $25.00 per million output tokens ($10.00/M blended at 3:1). Renowned for exceptional instruction adherence, complex code synthesis, and analytical consistency. Verified 2026-09-08.
How much does Claude Opus 4.6 cost per 1,000 requests?
Computed from generated token pricing. Each row assumes the listed input and output tokens per request; this model has no measured verbosity factor, so the unadjusted output estimate is shown.
| Request shape | Input tokens | Output tokens | Cost / 1,000 requests |
|---|---|---|---|
| Short | 100 | 50 | $1.7500 |
| Medium | 1,000 | 500 | $17.5000 |
| Long | 4,000 | 2,000 | $70.0000 |
Formula: ((input price × input tokens) + (output price × output tokens × verbosity factor)) ÷ 1,000,000 × 1,000. Assumptions: short 100/50, medium 1,000/500, long 4,000/2,000 input/output tokens per request. Unadjusted — no measured verbosity factor is available.
Batch 9 continuity economics for Claude Opus 4.6

| Long input | $100000.00 | $50000.00 | $150000.00 |
| Output-heavy | $20000.00 | $100000.00 | $120000.00 |
Formula: calls × (input tokens × $5.00/M + output tokens × $25.00/M) ÷ 1,000,000. Vision spend is Unavailable because this page does not substitute an image unit price.
2. Traffic-drain budget (fallback, not successor)
| Drain | Claude Opus 4.6 baseline | Claude Haiku 4.5 fallback | Blended monthly | Savings |
|---|---|---|---|---|
| 0% | $45000.00 | $9000.00 | $45000.00 | $0.0000 |
| 25% | $45000.00 | $9000.00 | $36000.00 | $9000.00 |
| 50% | $45000.00 | $9000.00 | $27000.00 | $18000.00 |
| 100% | $45000.00 | $9000.00 | $9000.00 | $36000.00 |
The 1M-call coding-agent shape is held constant. Claude Haiku 4.5 is labelled only as a same-provider fallback; it is not a successor.
