Claude Haiku 4.5

Overview

Anthropic's small, fast hosted model. Excellent instruction-following and strong safety behavior make it a popular choice for customer-facing assistants and moderation. Snappy latency and dependable uptime, first-party served only. It's priced well above the open small models, so it tends to win on quality-per-call rather than raw cost, and it shines when reliability and tone matter.
