DeepSeek 4 Flash local inference engine for Metal
Summary
AIThis week in AI was dominated by major infrastructure deals, the rise of local inference engines, and a growing debate around model distillation. The xAI/Anthropic Colossus data center deal sparked widespread discussion on Bluesky, with Simon Willison and Ethan Mollick highlighting its environmental and competitive implications. Meanwhile, antirez's ds4 repo — a local inference engine for DeepSeek 4 Flash on Metal — was starred by both lucidrains and simonw, signaling strong interest in on-device AI. The 'distillation panic' blog post by Nathan Lambert resonated with many, as the term 'distillation attacks' was criticized for mischaracterizing the practice. On the coding tools front, Simon Willison's live blog from Anthropic's Code w/ Claude event and his reflections on vibe coding and agentic engineering captured the tension between rapid prototyping and production reliability. GitHub also saw notable repos like petgraph (Rust graph library) and roborev (continuous code review for agents) gain traction.
