Where Claude Opus 5.5 (batch) sits on price
At $10.00 per million output tokens, Claude Opus 5.5 (batch) is a premium tier model — 4.5× the median output price of $2.20, which puts it cheaper than 23% and pricier than 77% of the models we track. It sits 8th cheapest of the 29 Anthropic models we track. Output costs 5.0× input, the usual spread — trim both, starting with the answer length.
Cached input is 95% cheaper. On an input-heavy workload you need roughly a 26% 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 5.5 (batch)
These three workloads are the ones teams actually run on a premium-priced model — a $10.00/1M model is not bought for the same job as one ten times the price.
| Workload | Per request | Per month |
|---|---|---|
| Support chatbot — 500 conversations/day (5K in / 1.4K out) Conversation history re-sent each turn — the classic prompt-caching win. | $0.024 | $360 |
| Coding agent — 300 sessions/day (60K in / 12K out) Multi-step loops re-read the same files; caching matters more than raw price. | $0.24 | $2160 |
| Long-context analysis — 200 runs/day (250K in / 4K out) Only possible on large-context models; input cost is nearly the whole bill. | $0.54 | $3240 |

Frequently asked questions

› What does it cost to fill Claude Opus 5.5 (batch)'s 1M context window?

› Is Claude Opus 5.5 (batch) worth the price?
Claude Opus 5.5 (batch) sits in the middle of the market (8 of 29 by price within Anthropic). The honest test is a routing experiment: send the same 200 real requests to this model and to a tier below, and compare failure rate against the price gap — most teams find a majority of traffic never needed the pricier model.
