# Claude Opus 5 发布：接近 Fable 5 智能，价格减半，主动构建计算机视觉管道

## AI 点评

> 如果你关注大模型成本与能力的平衡，这次发布值得一看——Claude Opus 5 用一半的价格接近旗舰性能，而且主动编程能力暗示了AI自主性的新高度。安全领域的刻意限制也很耐人寻味，对AI治理研究者尤其重要。

## 速览

Anthropic 发布 Claude Opus 5，自称其智能接近旗舰模型 Claude Fable 5 但价格仅为一半，且在 Artificial Analysis 排行榜上超越 Fable 5。新模型定价与 Opus 4.8 相同，并提供快速模式。一个突出案例显示，模型在无法直接查看图纸的情况下，自主编写计算机视觉代码从像素中提取几何数据并重建3D模型。在网络安全方面，Opus 5 发现漏洞的能力接近 Mythos 5，但未训练利用能力。Anthropic 同时发布了提示指南。

## 关键点

- Claude Opus 5 在 Artificial Analysis 排行榜上领先，超越 Claude Fable 5。
- 定价与 Opus 4.8 相同，快速模式费用翻倍。
- 模型能主动编写计算机视觉管道，从像素中重建3D模型。
- 发现漏洞能力显著提升，但刻意未训练利用漏洞。

## 全文

Introducing Claude Opus 5 I've been offline kayaking with sea otters for much of today so I haven't had a chance to put Anthropic's new model Claude Opus 5 through its paces yet. The buzz is positive, and Anthropic's description of it as a "thoughtful and proactive model that comes close to the frontier intelligence of Claude Fable 5 at half the price" sounds promising. It's currently leading the Artificial Analysis leaderboard, in front of even Fable 5. It's priced the same as Opus 4.8, and continues to offer a "fast mode" at twice the cost of the base model. Based on this anecdote in the release post it sounds like it might be relentlessly proactive: On one Frontier-Bench task, Opus 5 was given a drawing of a machine part and asked to write code to rebuild it as a 3D FreeCAD model. However, in this task, the model was intentionally given no way to directly viewthe drawing. Opus 5 responded by writing its own computer vision pipeline to pull the geometry from the raw pixels, then reconstructed the full machine part. It's better at finding vulnerabilities but has deliberately not been trained on how to exploit them. Hopefully this means the US government won't shut it down! As with its predecessor, Opus 4.8, we’ve intentionally avoided training Opus 5 on cyber tasks. The model has nevertheless improved substantially on these tasks as a result of becoming more generally capable, and it comes close to Mythos 5 at finding cybersecurity vulnerabilities. However, it remains substantially behind Mythos 5 on the exploitation of those vulnerabilities—that is, in turning vulnerabilities into material cyber threats. Anthropic have published a prompting guide for Claude Opus 5. The first pelican I got was missing the bicycle wheels; the second attempt was better.
