The part of Claude's brain nobody built
Anthropic researchers discovered 'J-space,' an internal workspace in Claude that wasn't explicitly programmed but emerged during training, functioning similarly to human conscious thought. The newsletter also covers Tencent's efficient Hy3 model, Kyutai's Rocket League world model, and practical AI applications including mobile app development with Replit.
Meta sizes up GPT-5.5 with 'Watermelon'
Meta's upcoming 'Watermelon' AI model reportedly matches OpenAI's GPT-5.5 performance while still in training, though the AI frontier continues advancing with competing models like Mythos and Fable. The newsletter covers Meta's $145B AI investment progress, practical AI applications from users, and emerging AI tools across education, coding, and consumer devices.
Altman invites Washington inside the AI industry
Sam Altman proposes a U.S.-led international AI safety forum modeled after the IAEA, with reports suggesting OpenAI discussed offering the government a 5% equity stake. Meanwhile, Meta's smart glasses capture 80% of the market but still fall short of replacing phones, and specialized AI models trained on expert data outperform frontier models at significantly lower costs.
Anthropic's Fable returns worldwide
