China's AI sector is set for a big week with several new models about to launch. A 'stealth' model has appeared quietly, adding intrigue to the booming scene. Alibaba Cloud is leading the charge, announcing its next-generation AI family with Qwen-3.5. This follows nearly a year after their Qwen-3 release, which helped the model family become the most popular open model worldwide in 2025. Alibaba Cloud shared new code on platforms Hugging Face and GitHub, where developers collaborate openly. Qwen-3.5 will come in two versions: one with 9 billion parameters and another with 35 billion. Parameters are like 'brain cells' for AI, and more means stronger AI but needs more computing power. For the first time, Qwen-3.5 will support multimodal data, meaning it can understand and work with text, images, and audio. It uses Alibaba's cutting-edge AI architecture first seen in their experimental Qwen3-Next model last September. This move aims to boost China's domestic AI competition after strong releases from US companies. With excitement building, China's AI arms race is racing forward with fresh power and mystery, promising significant upgrades for users and developers alike.
