OpenAI's starts training GPT-5 🤖 // Jan Leike joins Anthropic's Superalignment Team 👥 // MoEUT Outperforms Standard Transformers 💥

OpenAI has formed a new safety team to address concerns about AI safety and ethics, led by CEO Sam Altman and board members Adam D’Angelo and Nicole Seligman. Jan Leike, a leading AI researcher, has left OpenAI and joined Anthropic's Superalignment team, which is focused on AI safety and security. The latest version of Sentence Transformers v3 has been released, allowing for finetuning of models for specific tasks like semantic search and paraphrase mining. Exciting new research papers have been published, including MoEUT, a shared-layer Transformer design that outperforms standard Transformers on language modeling tasks, and EM Distillation, a new distillation method for diffusion models that efficiently distills them to one-step generator models without sacrificing perceptual quality.
