Claude Haiku 5.5: Anthropic's Cheapest, Fastest Small Model With Adjustable Effort, 1M Context, and Browser Use
On October 7, 2026, Anthropic released Claude Haiku 5.5 — the cheapest, fastest, and most capable small model in the Claude 5.5 family. At $0.10/$0.50 per million tokens (up to 100K context), it costs 75% less than Haiku 4.5 on average, scores 1620 on GDPval-AA v2.1, 72.4% on OSWorld 2.1, and 46.4% on FrontierCode 1.1. The first Haiku with adjustable effort settings, 1M context, and native browser use support, Haiku 5.5 is designed for high-volume subagent work, real-time experiences, and cost-sensitive agentic tasks. Released alongside a 50% price cut on Sonnet 5.5 cache reads and new monthly API credits for Max and Team subscribers.
