Published price history
This chart appears only when at least two dated first-party price records exist for the exact model. It shows rate changes, not an inferred cost trend.
3 dated first-party price records. The newest record lists $5 per million tokens.
Lineage
The sequence follows explicit supersedes links. A successor's displayed score stays at least 0.1 points above its predecessor; raw benchmark rows do not move. Scores and prices remain blank when the corresponding public row or first-party rate is unavailable.

Frequently asked questions
How does Claude Haiku 4.5 perform overall in AI benchmarks?
Claude Haiku 4.5 ranks #94 out of 230 models on the public BenchAlign leaderboard, with a score of 57.58/100. Its evidence status is Estimated, and this profile shows 5 source-displayable benchmark rows. The label describes evidence depth, not a provider quality claim; inspect category rows before choosing a workload.
Is Claude Haiku 4.5 good for coding and programming?
Claude Haiku 4.5 ranks #97 out of 148 eligible models for coding and programming, with a public category score of 47.9/100. Higher-ranked alternatives are available for workloads where this category decides the choice. Check the underlying rows before treating the aggregate as a workload guarantee.
Is Claude Haiku 4.5 good for mathematics?
Claude Haiku 4.5 has source-displayable benchmark coverage for mathematics, but the public category table does not assign it a rank there. The individual rows remain available for inspection. A missing category position means the evidence threshold was not met; it does not convert the model's unmeasured work into a zero.
Is Claude Haiku 4.5 good for agentic tool use and computer tasks?
Claude Haiku 4.5 ranks #58 out of 143 eligible models for agentic tool use and computer tasks, with a public category score of 51.8/100. Higher-ranked alternatives are available for workloads where this category decides the choice. Check the underlying rows before treating the aggregate as a workload guarantee.
Which sibling models are related to Claude Haiku 4.5?
Claude Haiku 4.5 belongs to the Claude Haiku 4.5 family. Related tracked variants include Claude Haiku 4.5 Thinking. A sibling link indicates shared lineage or a documented configuration relationship; it does not mean the variants have identical pricing, context limits, benchmark evidence, or deployment behavior. Compare before switching.
Does Claude Haiku 4.5 have full benchmark coverage on BenchLM?
No. Claude Haiku 4.5 currently has 6 source-displayable rows across 416 tracked benchmark slots. The profile exposes published, non-generated evidence and leaves missing categories blank until an exact evaluation is available. Coverage describes how much was measured; it is not a penalty added to an individual benchmark result.
What is the context window size of Claude Haiku 4.5?
Claude Haiku 4.5 has a documented context window of 200K. That figure is the maximum combined prompt and retained-conversation space reported for this exact model; it is not the maximum output length. The profile keeps output limits separate because providers often publish those limits independently.
