OpenAI tops ARC-AGI-3 📈, GPT-5.6 efficiency ⚙️, AlphaFold team dissolution 🧬

OpenAI's GPT-5.6 Sol model initially scored low on the ARC-AGI-3 benchmark, but enabling retained reasoning and compaction settings tripled its performance and reduced output tokens sixfold. Meanwhile, SpaceXAI released Grok Voice Think Fast 2.0, and Google's Lyria 3.5 music model launched with improved musicality and vocals. Additionally, researchers introduced efficient CPU-friendly long-context encoders and explored visual prompt engineering for video models.
