About this model

Claude Haiku 4.5 matches Sonnet 4's performance on coding, computer use, and agent tasks at substantially lower cost and faster speeds. It delivers near-frontier performance and Claude’s unique character at a price point that works for scaled sub-agent deployments, free tier products, and intelligence-sensitive applications with budget constraints.

Replaces Claude 3 Haiku: input $0.2625 → $1.05 per 1M (+300%), output $1.3125 → $5.25 per 1M (+300%), same context window, max output 4K → 64K.
