种种迹象表明，Fenix Flexin 使用了 AI 音乐生成器 Treblo

我们此前已相当确信，Fenix Flexin 的《Rubberz》是使用 AI 制作的，但音乐人 Medasin确信它具体是由 Treblo 制作。如今，该公司及一款新的检测工具似乎证实了这一点。

周一，该公司宣布推出开源的 Treblo AI Music Classifier。该工具能够检测一首歌曲是否使用 Treblo 生成，但无法检测其他 AI 工具生成的作品。根据一篇博客文章，该工具的假阳性率低于万分之一。这并非无可置疑，但值得注意的是，该公司自家的 Classifier 将《Rubberz》判定为“极可能由 Treblo 制作”，且具有“高置信度”，这进一步加剧了 Fenix 面临的公关噩梦。

Treblo 似乎也颇为享受由此获得的关注。CEO Ryan Tremblay 在向 The Verge 发表的声明中说：“该分类器为《Rubberz》返回了极高的概率评分，表明发布的音频几乎完全由我们的模型生成。这将使它成为首支已知进入 Billboard Hot 100 的 AI 生成歌曲。”他接着说：“显然有人使用我们的模型找到了数百万人产生共鸣的一种声音，这令人兴奋。”

Fenix 仍持续否认《Rubberz》使用 AI 制作，并发布了他声称是录音期间工程文件的片段。然而，这些低清视频几乎未能消除任何有关该歌曲由 AI 生成的指控。据 Stereogum报道，Medasin 曾在一则现已过期的 Instagram Story 中表示，Fenix 显然只是使用了 AI 音轨分离器来伪造录音工程。

Fenix 未立即回应置评请求。

8 月 5 日更正： 本文最初称 Treblo 检测器的假阳性率为千分之一；实际为万分之一。

We were pretty sure that Fenix Flexin’s “Rubberz” was made using AI, but musician Medasin was confident that it was made using Treblo specifically. Now the company and a new detection tool seem to confirm it.

On Monday, the company announced the open-source Treblo AI Music Classifier, which detects when a song was generated using Treblo, though not other AI tools. According to a blog post, it has a false positive rate of less than 1 in 10,000. That’s not unimpeachable, but it’s notable that the company’s own Classifier determined that “Rubberz” was “very likely Treblo” with “high confidence,” adding more fuel to the PR nightmare for Fenix.

Treblo does seem to be relishing the attention a bit. “The classifier returns a very high probability score for Rubberz, indicating the released audio was generated almost entirely by our model. That would make it the first known AI-generated song to reach the Billboard Hot 100,” CEO Ryan Tremblay said in a statement to The Verge. He continued, “Someone appears to have used our model to find a sound that millions of people connected with and that’s exciting.”

Fenix has continued to deny that Rubberz was made using AI, and has posted clips of what he claims are the project files of the recording session. However, those low-quality videos have done little to dispel any allegations of the song being AI-generated. According to Stereogum, Medasin contended in a since-expired Instagram story that Fenix clearly just used an AI stem separator to fake the session.

Fenix did not immediately return a request for comment.

Correction August 5th: This story originally stated that the false positive rate for Treblo’s detector was 1 in 1,000; it is 1 in 10,000.
