Anthropic 推出了新一代模型 Opus 5。这是 Opus 系列的最新版本,距离 Opus 4.8 上线仅约两个月。公司称,Opus 5 的价格低于 Fable 5,限制也更少,在多数使用场景下更具实用性。

多项测试超过Fable 5

公告显示,Opus 5 在此次发布附带的多项基准测试中超过了 Fable 5。Anthropic 还强调,这一模型在验证自身输出、反复迭代直到完成任务方面表现更强。

公司举例称,在一项测试中,Opus 5 能根据不完整提示,自行写出一套计算机视觉流程。这也是其此次重点强调的能力之一。

不受30天数据保留约束

与 Fable 和 Mythos 不同,Opus 5 不受 30 天数据保留政策约束。Anthropic 表示,这一点与上一代 Opus 保持一致。此前,这项安排曾引发部分重视隐私用户的担忧。

不过,Opus 5 并非完全放开。Anthropic 仍对网络安全相关任务保留较强防护,尤其是漏洞利用生成和渗透测试等场景。比如,模型不能被用于扫描软件二进制文件中的漏洞,但可以用于查找源代码中的漏洞。

新增自动回退功能

Anthropic 同时推出一项名为 Automatic Fallbacks 的测试功能,供用户选择开启。若请求触发安全分类器,系统会自动将任务切换到能力较低的模型,而不是直接返回错误信息。

公司预计,针对 Opus 5 的安全分类器触发频率将比 Fable 5 低约 85%。对 API 用户而言,这意味着在更多请求中可以获得可用响应,减少因安全拦截带来的调用中断。
