Anthropic Launches Claude Haiku 4.5, a Cost‑Effective Small Model
Anthropic introduced Claude Haiku 4.5, a compact AI model designed to deliver high intelligence and speed at a fraction of the cost of its larger counterparts. Priced at $1 per million input tokens and $5 per million output tokens for API users, Haiku 4.5 undercuts Sonnet 4.5 and Opus 4.1 while matching frontier‑level performance on benchmarks such as SWE‑bench. The model targets real‑time, low‑latency tasks like chat assistants, customer service, and pair programming, and can be combined with Sonnet 4.5 in multi‑model workflows. Documentation and system cards are now available for developers.
