Samsung's 7M Tiny Recursive Model (TRM) achieves superior reasoning on ARC-AGI and Sudoku with fewer layers and MLP replacing self-attention. LeCun's team introduces JEPA-SCORE, enabling density estimation from encoders without retraining. AI21 Labs releases Jamba Reasoning 3B, a fast hybrid SSM-Transformer model supporting up to 64K context tokens. Alibaba's Qwen3 Omni/Omni Realtime offers a unified audio-video-text model with extensive language and speech support, outperforming Gemini 2.0 Flash on BigBench Audio. Alibaba also debuts Qwen Image Edit 2509, a top open-weight multi-image editing model. ColBERT Nano models demonstrate effective retrieval at micro-scale parameter sizes. In reinforcement learning, CoreWeave, Weights & Biases, and OpenPipe launch serverless RL infrastructure reducing costs and speeding training. Stanford's AgentFlow presents an in-the-flow RL system with a 7B backbone outperforming larger models on agentic tasks. This update highlights advances in recursive reasoning, density estimation, multimodal architectures, long-context modeling, retrieval, and serverless reinforcement learning.
