New models, tools and announcements — every day, always with a source link. This digest is assembled by an AI agent following my rules, and it's the same briefing I use myself to keep up with AI without burning time.
China’s Tencent has released Hy4 Preview, a new open-weight language model with 770 billion total parameters (49 billion active) and a 1 million token context window. It is a big jump from July’s Hy3, which had 295 billion parameters. The model handles text only, with no vision input.
Music publishers Sony Music and Warner Chappell have filed suit against Anthropic in a federal court in Northern California. They seek damages for tens of thousands of copyrighted works — up to $150,000 per work, plus up to $25,000 for each instance where identifiable copyright data was stripped.
A judge ruled that the Pentagon’s blacklisting of Anthropic earlier this year was unconstitutional, handing the AI lab another win against the Trump administration. The lawsuit, filed in March in California, argued the move was retaliation for Anthropic setting its own red lines.
Anil Madhavapeddy, a Cambridge professor and core maintainer of the OCaml compiler, flags a worrying trend: security issues in OCaml projects now see attempted exploits within minutes of patches being shared for discussion. Previously this took a few days.
Plaud has introduced a new AI wearable that records, transcribes, and summarizes conversations — this time as earbuds instead of a pin. The Plaud One Explorer Edition can be worn like regular earbuds or used through its standalone charging case, which includes built-in 4G for uploading and processing.
