Anthropic launches Claude Opus 5.5, promising better performance at a lower price

Anthropic has officially released Claude Opus 5.5, the latest addition to its AI model family. The company claims this new model delivers performance comparable to its Fable 5.1 model while significantly reducing operational costs by approximately 40 percent compared to the previous Opus 5 iteration. Opus 5.5 demonstrates strong capabilities in coding, computer use, and knowledge-based tasks, outperforming several competitors in benchmark testing. Anthropic has also implemented enhanced safety protocols, including rigorous behavioral audits and restricted access to sensitive biology and cybersecurity domains. The model is now available via major cloud platforms, including AWS, Google Cloud, and Microsoft Azure, with reduced API pricing for input, output, and cache read tokens. As Anthropic continues to scale its offerings, it remains focused on balancing frontier-level capabilities with proactive safety measures, acknowledging the ongoing challenges of evaluating advanced AI behavior in real-world scenarios.
