Its ease of download and modification has led to integration across a range of products, from smart glasses to vehicle dashboards, and adoption by companies such as Rokid, BYD, Airbnb, Perplexity, Nvidia, and even Meta.

A coalition of writers, led by Theranos whistleblower and author John Carreyrou, has filed a lawsuit against six major artificial‑intelligence companies—Anthropic, Google, OpenAI, Meta, xAI and Perplexity. The suit alleges the firms trained large language models on pirated copies of the authors’ books, violating copyright. The complaint references an earlier class‑action case in which a judge ruled that while using pirated material to train models may be lawful, the act of pirating the books itself is illegal. Authors claim the recent $1.5 billion Anthropic settlement, which offers modest payouts to eligible writers, favors the AI companies and fails to hold them accountable. Leer más →
