The device is a cap rather than an implant.

Mathematicians reacted with mixed feelings, and the post highlights concerns about unread papers, cryptography implications, and the role of Lean verification.

AITian Keyu, the Peking University PhD student known as the "ByteDance poisoning intern," has a 10-person world-model lab valued at $200 million after $30 million from Fivesource Capital and IDG, according to Leiphone. The lab plans to train a foundation model on about 100 million hours of video using a 200,000-symbol visual vocabulary, with a 2027 release targeted.

AIOpenAI reportedly assured investors it expects to reach a $70 billion annualized revenue target this year, an apparent effort to ease concerns that it is missing earlier projections. The figures matter because they are seen as a gauge of underlying demand for cutting-edge AI models and a justification for huge spending on tech infrastructure. Some analysts, however, say the annualized revenue metric itself is flawed.
