Anthropic completes the Claude 5.5 lineup with Haiku and expands its Cyber Verification Program to three tiers

Haiku 5.5 is the third Claude 5.5 model released in a month. It targets classification, summarization, extraction, live support and voice workloads.

The Cyber Verification Program now offers three tiers: Defense, Red Team and Specialized Access.

Reuters ties the rapid release cadence to Anthropic's planned IPO.

Developers flagged a fivefold price jump for Haiku 5.5 prompts above 100K tokens.
