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.
