Where Claude 3 Haiku sits on price
At $1.25 per million output tokens, Claude 3 Haiku is a mid tier model — 1.7× cheaper than the median output price of $2.08, which puts it cheaper than 62% and pricier than 38% of the models we track. It is the cheapest of the 27 Anthropic models we track. Output costs 5.0× input, the usual spread — trim both, starting with the answer length.
Cached input is 88% 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 3 Haiku
These three workloads are the ones teams actually run on a mid-priced model — a $1.25/1M model is not bought for the same job as one ten times the price.

| Document pipeline — 10K docs/day (3K in / 500 out) Batch-friendly: no user waiting, so a ~50% batch discount usually applies. | $0.0014 | $413 |
| Small app — 1K requests/day (500 in / 150 out) The baseline most side projects actually run at. | $0.0003 | $9.37 |

› What does it cost to fill Claude 3 Haiku's 200K context window?
Sending 200K of input in a single request costs $0.05 at $0.25 per million tokens — before any output. With prompt caching that same fill drops to about $0.006 on repeat requests. This is why large context windows are cheap to advertise and expensive to actually use.
› Is Claude 3 Haiku worth the price?
Claude 3 Haiku sits in the middle of the market (1 of 27 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.
