s1: Simple test-time scaling (and Kyutai Hibiki)

**"Wait" is all you need** introduces a novel reasoning model finetuned from **Qwen 2.5 32B** using just **1000 questions with reasoning traces** distilled from **Gemini 2.0 Flash Thinking**, enabling controllable test-time compute by appending "Wait" to extend reasoning. Lead author **Niklas Muennighoff**, known for work on **Bloom**, **StarCoder**, and **BIG-bench**, highlights this method's efficiency and its reproduction of the famous o1 scaling chart. Additionally, **Kyutai Moshi**'s Hibiki project demonstrates impressive offline French-English live translation on iPhone. Recent AI model releases include **DeepSeek R1 and R3 open source models**, potentially marking a major open-source milestone, **Hugging Face's SmolLM2** emphasizing data-centric training for small LMs, and **IBM's Granite-Vision-3.1-2B**, a small vision-language model with strong performance. Key research papers spotlight **LIMO** for minimal demonstration reasoning achieving high accuracy on AIME and MATH benchmarks, and **Token-Assisted Reasoning** mixing latent and text tokens to improve language model reasoning.
