Anthropic releases Claude Opus 5.5, beating Fable 5.1 on key agentic benchmarks at 60% cheaper API price

Anthropic has upended the high-stakes competition for AI dominance by releasing Claude Opus 5.5, a model that outperforms a rival's flagship system on critical real-world task benchmarks while undercutting it by nearly 40 percent on pricing. The move signals that the artificial intelligence arms race is no longer just about raw capability—it's about who can deliver superior performance at scale affordably. With major tech firms racing to deploy AI agents capable of autonomous decision-making, Anthropic's latest model threatens to reset expectations about the price-to-performance ceiling in one of the industry's most consequential technological transitions.
