Anthropic ships Claude Haiku 5.5: 75% cheaper than Haiku 4.5, plus Sonnet 5.5 cache reads halved

Anthropic calls Haiku 5.5 its cheapest, fastest and most capable small model, costing about 75% less than Haiku 4.5 on average. It scores 72.4% on OSWorld 2.1 (offline subset) against 48.9% for GPT-6 Luna, and 46.4% on FrontierCode 1.1 versus 42.4%. It is the first Haiku with an adjustable effort setting.

Anthropic also halved Sonnet 5.5 cache-read pricing (about 20% cheaper on most agentic work) and is adding a monthly API credit for Max and Team subscribers.

Why it matters: A cheap, fast model suits high-volume classification, summarisation and browser-use workloads, including KwikGEO prompt-tracking and extraction jobs.
