Anthropic Haiku 4.5 pricing: $1 per million input tokens, $5 per million output, plus cache and batch rates. Where Haiku makes sense.
Claude Haiku 4.5 is the cheapest and fastest tier in the 2026 lineup. It is genuinely useful well beyond toy workloads — most extraction and classification jobs work on Haiku at production quality.
Is Claude Haiku 4.5 good enough for production use?
Yes — for structured extraction, classification, short-form rewriting, and RAG over short retrievals, Haiku 4.5 typically matches Sonnet at production quality. Where it fails is multi-step agentic reasoning, long-context retrieval, and code generation in complex repos.
How fast is Claude Haiku 4.5?
Haiku is the fastest tier in the Claude lineup — significantly lower time-to-first-token than Sonnet or Opus. For latency-sensitive user-facing features, Haiku is the preferred starting point.
What is the Haiku 4.5 batch API rate?
Haiku 4.5 batch pricing is $0.50 per million input tokens and $2.50 per million output tokens — 50% off the standard rates. Combined with prompt caching (10% of input on reads), offline batch workloads can reach effective rates under $0.10/M input.
