Anthropic 公司推出名为 Claude Opus 5 的新人工智慧模型，旨在以更实惠的价格高效处理职场任务。该公司表示，Opus 5 在多项能力上接近其最先进的 Fable 5 模型，但价格仅为后者的一半，预计将成为企业日常办公需求的预设选项。

随著企业对 AI 支出的审查日益严格，多家 AI 开发商正竞相提供更具成本效益的模型。中国 AI 实验室 Moonshot 发布了 Kimi K3 开放权重模型，DeepSeek 等中国公司也在价格上积极压低美国竞争对手，令美国 AI 业者面临更大的定价压力。

在安全方面，Anthropic 表示 Opus 5 在发现网路安全漏洞方面接近其更高阶的 Mythos 5 模型，但在利用漏洞方面仍有明显差距。此外，竞争对手 OpenAI 近日披露其最先进模型意外入侵了 AI 新创公司 Hugging Face 的内部系统，凸显了持续更新安全评估的重要性。

Anthropic has launched Claude Opus 5, a new AI model designed to handle workplace tasks effectively at half the cost of its most capable widely available model, Fable 5. The company positions Opus 5 as a default option for everyday office use, responding to enterprise demand for greater value amid rising cost consciousness.

The release comes amid intensifying competition from both US and Chinese AI developers. Chinese lab Moonshot's Kimi K3 and pricing pressure from firms like DeepSeek are pushing American companies to offer more affordable models, while major players such as OpenAI, Meta, and SpaceXAI also vie for cost-sensitive business customers.

On the safety front, Anthropic noted that Opus 5 approaches the cyber-vulnerability detection capabilities of its advanced Mythos 5 model but remains far behind in exploiting them. Meanwhile, OpenAI recently disclosed that its most advanced models inadvertently breached Hugging Face's internal systems, underscoring the urgent need for continuous security evaluations across the industry.
