Meta 已发布 Muse Spark Open 的权重，这是一款编码和代理模型，Meta 称其不如周一发布的 Muse Wonder 前沿模型先进。Meta 首席人工智能官 Alexandr Wang 表示，Meta 通常不会开源其最强大的模型，而这一点正是欧盟《人工智能法案》开源豁免所围绕的分歧。
Meta has published the weights for Muse Spark Open, a coding and agent model it says is less advanced than the Muse Wonder frontier model it launched on Monday. Chief AI officer Alexandr Wang said Meta will generally not open-source its most powerful models, which is the split the EU AI Act’s open-source exemption is built around.
Meta 已发布其称之为有意并非最佳模型的权重，并将该政策公开记录。在欧洲，这种分歧正是《人工智能法案》开源豁免所建立的基础。
Meta has published the weights for a model it says is deliberately not its best, and put the policy on the record. In Europe, that split is the one the AI Act’s open-source exemption is built around.
彭博社周四报道了此次发布。Muse Spark Open 专为编码和代理而构建，Meta 表示其能力不如 Muse Wonder，后者于周一发布。
Bloomberg reported the release on Thursday. Muse Spark Open is built for coding and agents, and Meta says it is less capable than Muse Wonder, which launched on Monday.
“由于安全和能力的双重考虑，我们通常不会开源我们最强大的模型，” Alexandr Wang 说。他表示，Meta 有意继续发布优秀的开源模型。
“Because of both safety and capabilities, we will generally not open-source our most powerful models,” Alexandr Wang said. He said Meta intends to keep releasing good open models.
这些权重托管在 Hugging Face、Amazon SageMaker AI 和 Google Cloud Model Garden 上。其中一个提供服务的平台是 Nebius，这是 Meta 已承诺最高投入 270 亿美元的荷兰公司。
The weights sit on Hugging Face, Amazon SageMaker AI and Google Cloud Model Garden. One platform serving it is Nebius, the Dutch firm Meta has committed up to $27B to.
Meta 周一表示，Muse Wonder 已达到前沿水平，且未发布任何基准测试。该模型仍保持闭源。
Meta said on Monday that Muse Wonder had reached the frontier, and published no benchmarks. That model stays closed.
这是 Muse 系列的第二次开源发布。Meta 在八月曾发布 Glimmer，这是一个从 Muse Spark 蒸馏出的 300 亿参数模型，采用 Apache 2.0 许可证。Meta 还与 Apple 合作，使新模型能够在两台 M5 Ultra Mac Studio 上运行。
This is the second open release from the Muse line. Meta published Glimmer in August, a 30-billion-parameter model distilled from Muse Spark, under Apache 2.0. It also worked with Apple so the new model runs on two M5 Ultra Mac Studios.
九月时，公司尚未决定是否发布 Muse Spark 1.3 的权重。如今，它通过发布另一款模型来作出回应。
In September the company had not decided whether to publish the weights for Muse Spark 1.3. It has answered with a different model instead.
《人工智能法案》第 53 条豁免真正免费和开源的模型，使其无需向人工智能办公室提交文档。但该豁免在系统性风险处终止——无论许可证如何，所有义务均适用。
Article 53 of the AI Act exempts a genuinely free and open model from the documentation owed to the AI Office. The exemption stops at systemic risk, where every obligation applies whatever the licence.
Meta 的创始人五周前曾表达近乎相反的观点。扎克伯格在《Sources》播客中表示，竞争对手训练更先进的模型却不发布它们是相当危险的。他未点名任何公司。
Meta’s founder said close to the opposite five weeks ago. Zuckerberg told the Sources podcast that rivals training more advanced models and then not releasing them was quite dangerous. He named no company.
委员会可以处以全球营业额3%的罚款，并在发布前要求进行评估。Meta 拒绝签署为落实这些职责而制定的行为准则，乔尔·卡普兰去年表示欧洲正走在错误的道路上。
The Commission can fine 3% of global turnover and demand evaluations before release. Meta declined to sign the code of practice written to operationalise those duties, and Joel Kaplan said last year that Europe was on the wrong path.
王表示，全球大多数人工智能将运行在开放模型上，并且这些模型应该是美国的。早在八天前，阿里巴巴董事长蔡崇信在都灵的一次会议上表示，开源是欧洲实现独立的唯一途径。
Wang said most of the world’s AI will run on open models, and that they should be American. Eight days earlier, Alibaba chairman Joe Tsai told a Turin conference that open source was Europe’s only way to independence.
王期望中国开发者能够在 Muse Spark Open 的基础上进行开发，并表示如果他们采纳其原则甚至可能是件好事。
Wang expects Chinese developers to build on Muse Spark Open, and said it might even be good if they adopted its principles.
欧洲自身的答案已经在市场中出现。Mistral 推出了 Large 4，这是一个万亿参数的开放权重模型，旨在挑战中国在此类别中的领先地位。
Europe’s own answer is already in the market. Mistral launched Large 4, a trillion-parameter open-weight model, to take on China’s lead in this category.
