Why It Matters

The release signals a push to prove safety and efficiency can coexist as the company faces political scrutiny over its regulatory stance, with implications for enterprise adoption and policy debates.

Summary

Anthropic launched Claude Haiku 4.5, a lightweight AI model that it says matches Claude Sonnet 4’s coding performance while running twice as fast and at one-third the cost. The model is available across Anthropic’s apps, Claude Code, Amazon Bedrock and Google Vertex AI, priced at $1 per million input tokens and $5 per million output tokens. Anthropic calls Haiku 4.5 its safest model yet with a lower misalignment score and an AI Safety Level 2 rating, positioning it for real-time developer use in chat, coding copilots and customer service. The release signals a push to prove safety and efficiency can coexist as the company faces political scrutiny over its regulatory stance, with implications for enterprise adoption and policy debates.
