Anthropic launches Claude Opus 5.5 with token prices cut 20% to $4 and $20 per million

AI Market Summary
Anthropic’s Claude Opus 5.5 cuts token pricing ~20% versus Opus 5 while claiming near-Fable 5.1 performance, raising competitive pressure in AI inference economics and potentially shifting demand toward higher-usage workloads (agentic coding, long-context tasks). The release also highlights governance risk management: third-party evaluations (METR, Frontier Design) align with EU AI Act Article 55 obligations, which can influence compliance costs, timelines, and incident-reporting scrutiny for frontier model providers.

Anthropic has released Claude Opus 5.5, pricing it at $4 per million input tokens and $20 per million output tokens, down 20% from Opus 5. The company said the model performs similarly to the more expensive Fable 5.1 on most tasks. It is Anthropic’s first model since CEO Dario Amodei called for third-party evaluations, which Article 55 of the EU AI Act has required in Europe since August 2025.
