Context window and output limits
What Claude Haiku 4.5 can hold in a single request, and where ByteCosts stops short of a source-backed claim.
- Context window: not part of this committed pricing record; check the provider page for the current limit.
- Maximum output tokens: not a field in this committed pricing record. ByteCosts only states source-backed numbers, so treat the provider documentation as authoritative for the per-response output cap.
What it costs at real workloads
Each row is computed from this record's committed input and output token prices with the ByteCosts cost engine. Assumptions are shown inline.
| Workload | Assumed monthly tokens | Estimated token cost |
|---|---|---|
| Light reference | 1M input + 250K output tokens/month | $2.25 / month |
| Production reference | 10M input + 2.5M output tokens/month | $22.50 / month |
| Heavy reference | 100M input + 25M output tokens/month | $225 / month |
Best-fit workloads for Claude Haiku 4.5
Where this price profile is cost-effective, and where it is not, derived from the committed input, output, cache, and context fields.
- Good fit: Repeated-prefix agents and chat with a stable system prompt: cached input reads list at $0.100 per 1M, well below the $1.00 fresh-input rate.
- Good fit: Input-heavy, short-output work (RAG, extraction, classification, reranking pre-filters): output costs about 5.0x input here, so keeping responses tight protects the budget.
- Not ideal: High-volume long-form generation: output is about 5.0x the input price ($5.00 vs $1.00 per 1M), so verbose or reasoning-heavy responses dominate the invoice.

Evidence, freshness, and limitations
ByteCosts grades this Anthropic Claude Haiku 4.5 row A+: Read from the provider's official pricing page. The record was first tracked on 2026-05-30 and last checked on 2026-06-27, and the source URL stays attached so you can verify the provider source before a purchasing or architecture decision.
Every number here is a planning estimate, not a quote.

Verify the provider source and quote the last-checked date with any copied figure, because model prices change often.
