Tencent's open flagship, music's lawsuit, a free stem splitter

As of today, a business owner who wants frontier-class AI without sending company data to a cloud vendor can download Tencent's new open model and run it privately, or try it free in Tencent's own apps.
It beat its Chinese rivals in a blind test. Then Tencent gave it away
Tencent released and open-sourced Hy4 preview on Friday, its largest model to date, and the files are on Hugging Face with an open license, no waitlist. Anyone can download them today. The model also runs inside Tencent's own apps, and through an API on OpenRouter and Tencent Cloud.
The score that matters is Tencent's own blind evaluation: *163 experts judged it across 203 engineering tasks, and it averaged 2.99 out of 4.00*, just ahead of GLM-5.3 and Kimi K3, the other open models everyone has been watching this month.
For a business that does not want company data leaving the building, the practical sentence is short: a model that beats the current open leaders now runs on a machine you own. The catch is honest: the evaluation is Tencent's own, so treat the margin as a signal, not a verdict.
Sony and Warner sue Anthropic, and this time the founders are on the line
One day after a federal judge struck down the Pentagon's blacklist of Anthropic, the two remaining major music publishers filed their own case. Sony Music Publishing and Warner Chappell Music sued Anthropic on Friday, and named co-founders Dario Amodei and Benjamin Mann as individual defendants. The complaint calls it "one of the largest and most blatant ongoing thefts of intellectual property in history."
The numbers are the story. The publishers seek statutory damages of up to *$150,000 per work willfully infringed, plus $25,000 for each removed credit. The complaint alleges that in June 2021 Amodei's co-founder downloaded at least five million* pirated books from Library Genesis, figures drawn from a prior case where a judge described the conduct as "straightforward piracy but at massive scale."
For a music lawyer, a label executive, or a founder shipping any AI product that touches songs, the ground just shifted: the biggest names in music are now all litigating against the same lab, and the founders are personally in the case. Settlements get likelier; so do years of discovery.
Stem separation, freed from the cloud
A free open-source tool called StemDeck splits any song into *six stems*: vocals, drums, bass, guitar, piano, and everything else. It takes an MP3, a WAV, or even a YouTube link, and does the work on your own machine. No account, no upload, no subscription, and nothing leaves your computer.
The paid cloud services that do this cost a monthly fee and hold your audio on their servers. StemDeck is the opposite trade: less polish, full privacy, and the price of a download. It builds on the open-source Demucs engine, so it works even on machines without a graphics card.
For a musician, a podcaster, or a karaoke host, a studio trick that used to mean a subscription is now a local install.
Weak signal
On Tuesday, hardware security keys become mandatory for every individual Daybreak account, Blue and Red alike. OpenAI announced the deadline on August 10, and nothing has slipped since. If you or your team use Daybreak, the key needs to exist before Tuesday.
Come Tuesday, every Daybreak account needs a hardware key, and the music case starts its long walk through the courts.
