PBC公布了其强大的Mythos和Fable人工智能模型的新版本，旨在巩固该公司在AI开发领域的领先地位，而其备受期待的华尔街上市即将到来。
PBC has unveiled new versions of its powerful Mythos and Fable artificial intelligence models, an effort to bolster the company’s position as a leader in AI development on the eve of its long-awaited Wall Street debut.
Anthropic表示，Fable 5.2将于周一发布，能够处理更困难的软件工程工作，承担更多与硬件相关的任务，例如控制机器人，并处理长期项目。它还设计为一次可协调超过1000个AI代理。Mythos 5.2是同一款模型，但在网络安全和生命科学工作方面的安全防护较少，正通过之前宣布的验证计划向选定的组织推出。Anthropic表示，这两款模型比之前的版本更快，且Fable的成本更低。
Anthropic said Fable 5.2, set to be released Monday, can tackle more difficult software engineering work, take on more hardware-related tasks like controlling robots and handle long-running projects. It’s also designed to coordinate over 1,000 AI agents at a time. Mythos 5.2, the same model but with fewer safeguards for cybersecurity and life sciences work, is being rolled out to select organizations through a previously announced verification program. The two models are faster than prior versions, Anthropic said, and Fable is less expensive.
这些发布有望帮助Anthropic抵御OpenAI等竞争对手的挑战，因为AI市场竞争日益激烈，而这家Claude开发商最早将于本月进行具有里程碑意义的公开上市。然而，此次公告也可能引发对该公司的进一步审查，因为许多科技行业内外人士正在警告AI可能带来的灾难性安全风险。美国中期选举中民主党的全面胜利也预计将推动有意义的AI安全监管取得进展，并为构建用于训练和运行AI模型的数据中心制造新的障碍。
The releases are poised to help Anthropic fend off challenges from rivals like OpenAI in an increasingly competitive market as the Claude maker nears a landmark public listing as soon as this month. However, the announcement may also invite further scrutiny for the company at a moment when many inside and outside the technology industry are warning about AI’s potential catastrophic safety risks. The Democratic sweep in the US midterm elections is also expected to boost momentum for meaningful AI safety regulation, and create new roadblocks for building the data centers used to train and run AI models.
九月中旬，Anthropic首席执行官达里奥·阿莫代伊呼吁顶尖人工智能公司放缓其最先进模型的开发进度。此前几天，该公司一名人工智能研究人员辞职，并表示从事人工智能开发的人士认为，人工智能可能在本世纪末杀死所有人类。Anthropic自九月初以来未发布新版本的Fable和Mythos。负责Anthropic研究产品管理的黛安·佩恩表示，该公司针对最新模型采用了更长的测试期，以应对节奏问题，测试涉及更多以及新型的评估方法。
In mid-September, Anthropic Chief Executive Officer Dario Amodei called on top AI firms to slow the development pace of their most advanced models, days after an AI researcher at the company quit his job and said the people building artificial intelligence believe it could kill all humans by the end of the decade. Anthropic has not released a new version of Fable and Mythos since early September. Dianne Penn, who leads research product management at Anthropic, said the company addressed the idea of pacing with lengthier testing periods for the latest models that involved more — and new types of — evaluation methods.
“节奏放缓不等于暂停，”佩恩说。四月发布的Mythos原版是网络安全领域的一个里程碑，因为该模型能够发现并可能利用关键软件中的安全漏洞。Anthropic最初将发布限制在某些政府机构、金融机构和主要软件提供商，以防止黑客攻击。两个月后发布的Fable旨在将Mythos的功能带给更广泛的市场，同时阻止用户进行网络安全任务。
“Pacing is not like pausing,” Penn said. The original version of Mythos, unveiled in April, was a watershed moment for cybersecurity because of the model’s ability to spot and potentially exploit security vulnerabilities in critical software. Anthropic initially limited the release to certain government agencies, financial institutions and major software providers in a bid to stave off hacks. Fable, released two months later, was designed to bring Mythos capabilities to the wider market while blocking users from carrying out cybersecurity tasks.
由于美国政府对两款人工智能模型能力的安全担忧，六月对这两款模型实施了访问限制；Anthropic在Fable 5中添加了分类器，使模型能够发现并阻止更多网络安全任务后，对Fable 5的限制被解除。Mythos 5的访问权限后来也恢复了，但仅面向较小的用户群体。佩恩表示，Anthropic正在增加能够访问Mythos的公司数量，该软件的新版本将提供给美国和国外的公司。
US government safety concerns about the capabilities of both AI models led it to impose access restrictions for the two models in June; the limits were lifted for Fable 5 after Anthropic added classifiers that allow the model to spot and block more cybersecurity tasks. Access to Mythos 5 was later restored, but to a smaller group of users. Penn said Anthropic is increasing the number of companies that are able to access Mythos, with the new version of the software being made available to firms in the US and abroad. (The prior version is also available to some non-US-based companies, she said.)
（她表示，旧版本也提供给一些非美国公司。）最近，Anthropic和其他人工智能开发者披露了其模型从本应与外界隔绝的测试环境中访问互联网后，渗透到外部组织的事件。
More recently, Anthropic and other AI developers have disclosed incidents of their models breaching outside organizations after accessing the internet from within testing environments that should have been sealed off.
这些报告加剧了人们对人工智能系统可能以不可预测和有害方式行动的担忧。
These reports have heightened concerns about the potential for AI systems to act in unpredictable and harmful ways.
Penn表示，美国政府和第三方评估者在新模型推出前进行了审查并提供了反馈。她说，该公司开发了新的评估措施，用于测试模型逃出数字沙箱的可能性，并发现新版Fable和Mythos比早期版本更不太可能这样做。
Penn said the US government, and third-party evaluators, reviewed and gave feedback on the new models prior to launch. The company developed new evaluation measures to test for how likely a model is to break out of digital sandboxes, she said, and found the new Fable and Mythos were less likely than prior versions to do so.
随着Anthropic推进新版Fable，它面临着另一个挑战：成本。根据Ramp在8月发布的数据，该公司最顶级、也是最昂贵的产品仅占其模型整体支出的11%。Ramp当时表示：“通过Fable 5，我们发现了企业愿意为人工智能支出的新上限。”Anthropic表示，Fable最新版本的输入代币每百万代币8美元，输出代币每百万代币40美元，而Fable 5.1分别为10美元和50美元。
As Anthropic pushes ahead with a new version of Fable, it faces another challenge: costs. The company’s top-of-the-line — and priciest — offering accounted for just 11% of overall spending on the company’s models, according to data from Ramp released in August. “With Fable 5, we’ve found a new upper bound for how much businesses are willing to spend on AI,” Ramp said at the time. Anthropic said the newest version of Fable costs $8 per million input tokens and $40 per million output tokens, down from $10 and $50, respectively, for Fable 5.1.
