Anthropic releases Opus 5 with ‘close’ to Fable 5’s capabilities
Anthropic 发布 Opus 5，性能“接近” Fable 5
Weeks after Anthropic’s latest toe-to-toe with the US government, and days after an OpenAI security incident that dominated tech industry discussions, Anthropic on Thursday released its newest model, Claude Opus 5.
在 Anthropic 与美国政府最新一轮博弈结束数周后，以及 OpenAI 安全事件主导科技行业讨论的几天后，Anthropic 于周四发布了其最新模型 Claude Opus 5。
The company said in a release that Opus 5 “comes close to the capabilities of Claude Fable 5 in many domains” and is much better at complex coding tasks. (Fable 5 is the public-facing Mythos-class model that drew the government’s ire, was taken offline for a few weeks along with Mythos 5, and then brought back with even stronger cyber safeguards than before.)
该公司在新闻稿中表示，Opus 5 “在许多领域的能力接近 Claude Fable 5”，并且在处理复杂编码任务方面表现更佳。（Fable 5 是面向公众的 Mythos 级模型，曾引发政府不满，与 Mythos 5 一起被下线数周，随后在加强了网络安全防护措施后重新上线。）
The Fable 5 concerns — and the ensuing weeks of negotiations between Anthropic and the government — kicked off a new era of AI regulation for the Trump administration. Soon after, when OpenAI released GPT-5.6, it underwent a roughly two-week trial period of sorts, rolling out in limited preview solely to government-approved entities.
围绕 Fable 5 的担忧，以及随后 Anthropic 与政府之间长达数周的谈判，开启了特朗普政府人工智能监管的新时代。此后不久，当 OpenAI 发布 GPT-5.6 时，该模型经历了一个为期约两周的“试用期”，仅向政府批准的实体提供有限预览。

When asked whether Anthropic ran Opus 5 by the Trump administration before this public rollout, Anthropic spokesperson Danielle Ghiglieri told The Verge, “We continue to work with our government partners to conduct their own independent testing of our models. This includes Opus 5.”
当被问及 Anthropic 在此次公开发布前是否将 Opus 5 提交给特朗普政府审核时，Anthropic 发言人 Danielle Ghiglieri 告诉《The Verge》：“我们继续与政府合作伙伴合作，对我们的模型进行独立测试。这其中也包括 Opus 5。”
Anthropic is marketing Opus 5 especially to its enterprise customers, saying it’s best for knowledge work and biology and that it’s the ideal everyday model, with Fable 5 still being best for the most ambitious types of work and long-horizon AI agent projects. But the company was careful to say in a release that it has stronger cybersecurity safeguards than its predecessor, Opus 4.8, and that it’s “the most aligned Opus model and is the least susceptible to being tricked into misuse.”
Anthropic 正将 Opus 5 特别推向企业客户，称其最适合知识工作和生物学领域，是理想的日常模型；而 Fable 5 依然是处理最具挑战性的工作和长期 AI 智能体项目的最佳选择。但该公司在新闻稿中谨慎地表示，Opus 5 比其前身 Opus 4.8 拥有更强的网络安全防护，并且是“对齐程度最高、最不容易被诱导滥用的 Opus 模型”。
With the new model’s release, the company also seems to subtly address recent controversies over allegedly hidden usage caps — which have led to at least one lawsuit — and the AI money squeeze, or concerns that AI labs’ costs are being passed onto their customers in new ways. Per million tokens, pricing for Opus 5 is the same as its predecessor ($5 input / $25 output), and Anthropic made the point that it’s “half the price” of Fable 5. It’s also slightly cheaper than OpenAI’s GPT-5.6.
随着新模型的发布，该公司似乎也含蓄地回应了近期关于所谓“隐藏使用上限”（已导致至少一起诉讼）的争议，以及“AI 资金紧缩”问题，即人们担心 AI 实验室的成本正以新的方式转嫁给客户。Opus 5 的定价与前代产品相同（输入每百万 token 5 美元，输出 25 美元），Anthropic 特别指出其价格仅为 Fable 5 的“一半”。它也比 OpenAI 的 GPT-5.6 略微便宜。
Customers can also choose “Fast mode” for Opus 5 (a feature that’s being launched today in research preview), to get higher speeds for double the price. There’s also an option to opt in to automatic fallbacks to a lower-tier model when safeguards mandate that Opus 5 declines a user’s request.
客户还可以为 Opus 5 选择“快速模式”（该功能于今日以研究预览版形式推出），以双倍价格换取更高的运行速度。此外，当安全防护机制导致 Opus 5 拒绝用户请求时，用户还可以选择自动回退到低级模型。
