Anthropic launches Claude Opus 5.5, optimized for cost in long-context coding sessions

Anthropic 发布 Claude Opus 5.5，面向更长、上下文更重的编码会话优化成本

Anthropic released Claude Opus 5.5, explicitly targeting cost reduction for coding sessions that run long and use heavy context. The post body only contains the title and site navigation; it does not disclose pricing, benchmarks, or context-window specs. The one confirmed takeaway is the cost-optimization angle for extended coding workflows—everything else is still missing from the article.

Why it matters: Anthropic model launch is a signal, but the body is just a title and nav bar — all key facts are missing. H and R hit, K doesn't. Barely clears the featured threshold (≥2 of 3), but thin content caps the score at 72, the featured floor.
