Anthropic releases Claude Opus 5. 5 with improved performance and lower costs
Anthropic has released Claude Opus 5. 5, the first model in its new Claude 5. 5 series, designed for advanced coding, agentic tasks, and knowledge work. The model achieves performance levels comparable to the company’s high-end Claude Fable 5. 1 model while significantly reducing operational costs. For typical workloads, the cost is approximately 40% lower than its predecessor, Opus 5, driven by a 20% reduction in token pricing and a 60% reduction in cache-read costs.
Technically, Opus 5. 5 is over 30% faster than Opus 5 and features improved communication, using less jargon and placing key information earlier in responses. In benchmarks, it has outperformed OpenAI’s GPT-5. 6 Sol in software development tasks, specifically on the Terminal-Bench 4. 0. Anthropic also emphasized enhanced safety, noting that internal audits show the model is 85% less likely to attempt to bypass safety boundaries. The model is available via Claude’s web and mobile platforms, the Claude API, and through Amazon Web Services, Google Cloud, and Microsoft Azure. Anthropic also announced that Claude Sonnet 5. 5 and Claude Haiku 5. 5 are expected to follow in the coming weeks.
