Introducing Claude Opus 4.7
Apr 16, 2026
Our latest model, Claude Opus 4.7, is now generally available.
Opus 4.7 is a notable improvement on Opus 4.6 in advanced software engineering, with particular gains on the most difficult tasks. Users report being able to hand off their hardest coding work—the kind that previously needed close supervision—to Opus 4.7 with confidence. Opus 4.7 handles complex, long-running tasks with rigor and consistency, pays precise attention to instructions, and devises ways to verify its own outputs before reporting back.
The model also has substantially better vision: it can see images in greater resolution. It's more tasteful and creative when completing professional tasks, producing higher-quality interfaces, slides, and docs. And—although it is less broadly capable than our most powerful model, Claude Mythos Preview—it shows better results than Opus 4.6 across a range of benchmarks:
Last week we announced Project Glasswing, highlighting the risks—and benefits—of AI models for cybersecurity. We stated that we would keep Claude Mythos Preview's release limited and test new cyber safeguards on less capable models first. Opus 4.7 is the first such model: its cyber capabilities are not as advanced as those of Mythos Preview (indeed, during its training we experimented with efforts to differentially reduce these capabilities). We are releasing Opus 4.7 with safeguards that automatically detect and block requests that indicate prohibited or high-risk cybersecurity uses. What we learn from the real-world deployment of these safeguards will help us work towards our eventual goal of a broad release of Mythos-class models.
Security professionals who wish to use Opus 4.7 for legitimate cybersecurity purposes (such as vulnerability research, penetration testing, and red-teaming) are invited to join our new Cyber Verification Program.
Opus 4.7 is available today across all Claude products and our API, Amazon Bedrock, Google Cloud's Vertex AI, and Microsoft Foundry. Pricing remains the same as Opus 4.6: $5 per million input tokens and $25 per million output tokens. Developers can use claude-opus-4-7 via the Claude API.

介绍 Claude Opus 4.7
2026年4月16日
我们的最新模型 Claude Opus 4.7 现已正式发布。
Opus 4.7 在高级软件工程方面相比 Opus 4.6 有显著改进，在最具挑战性的任务上表现尤为突出。用户报告称可以满怀信心地将最困难的编码工作——那些以前需要密切监督的工作——交给 Opus 4.7。Opus 4.7 能够严谨一致地处理复杂、长时间运行的任务，对指令给予精确关注，并会想方设法在报告回结果前验证自己的输出。
该模型的视觉能力也大幅提升：能够以更高分辨率查看图像。在完成专业任务时，它更加优雅和有创意，能够生成更高质量的界面、幻灯片和文档。虽然它不如我们最强大的模型 Claude Mythos Preview 广泛，但在各种基准测试中，它的表现优于 Opus 4.6：
