**Alibaba** released compact dense **Qwen3-VL** models at 4B and 8B sizes with FP8 options, supporting up to 1M context and open vocabulary detection, rivaling larger models like **Qwen2.5-VL-72B**. Ecosystem support includes **MLX-VLM**, **LM Studio**, **vLLM**, **Kaggle models**, and **Ollama Cloud**. In video AI, **Arena** added **Sora 2** models leading in video benchmarks, with **Higgsfield Enhancer** improving video quality. **Runway** launched domain-specific workflow apps for creative tasks. Research on **Representation Autoencoders for DiTs (RAE-DiT)** shows improved diffusion model performance. On local training, **NVIDIA DGX Spark** enables strong local fine-tuning, while **Nanochat** by **Karpathy** offers a minimal stack for training and inference. **Together AI** introduced **ATLAS**, a speculative decoding method achieving up to 4× faster inference on **DeepSeek-V3.1**. These developments highlight advances in efficient model deployment, video AI, local fine-tuning, and inference speed optimization.
