Where Claude Opus 4.1 (batch) sits on price
At $37.50 per million output tokens, Claude Opus 4.1 (batch) is a frontier tier model — 16.7× the median output price of $2.25, which puts it in the most expensive 10% of everything we track. It sits 22th cheapest of the 28 Anthropic models we track. Output costs 5.0× input, the usual spread — trim both, starting with the answer length.
Cached input is 90% cheaper. On an input-heavy workload you need roughly a 28% cache-hit rate to take 25% off the input line — reachable for chatbots and agents that resend the same system prompt and history.
What real workloads cost on Claude Opus 4.1 (batch)
These three workloads are the ones teams actually run on a frontier-priced model — a $37.50/1M model is not bought for the same job as one ten times the price.
| Workload | Per request | Per month |
|---|---|---|
| Small app — 1K requests/day (500 in / 150 out) The baseline most side projects actually run at. | $0.0094 | $281 |
| Coding agent — 300 sessions/day (60K in / 12K out) Multi-step loops re-read the same files; caching matters more than raw price. | $0.9 | $8100 |
| Support chatbot — 500 conversations/day (5K in / 1.4K out) Conversation history re-sent each turn — the classic prompt-caching win. | $0.09 | $1350 |
