Chinese Alibaba Group has launched its latest model series, Qwen3.5, doubling down on open-weight access and agentic capabilities in what appears to be a bid to stay ahead in the market.
Released on the eve of the Lunar New Year, Qwen3.5 arrives in two formats: an open-weight model that developers can download, fine-tune, and deploy on their own infrastructure, and a hosted version—Qwen-3.5-Plus—available via Alibaba Cloud’s Model Studio. The launch follows closely on the heels of Alibaba’s recent robotics-focused AI model and comes amid a flurry of releases from domestic rivals, including ByteDance and Zhipu AI, each pushing deeper into agent-enabled systems.
Alibaba says the open-weight Qwen3.5 model contains 397 billion parameters and delivers improved performance and cost efficiency compared to earlier iterations. Though smaller than its previous flagship system, the company claims benchmark gains based on internal evaluations, asserting parity with leading models from OpenAI, Anthropic, and Google DeepMind. These comparisons, however, are self-reported and have not been independently verified.
Technically, Qwen3.5 reflects several dominant AI trends. It features “native multimodal” architecture, enabling simultaneous processing of text, images, and video within a single system. It also leans heavily into agentic functionality—supporting multi-step task execution with minimal supervision—and is compatible with open-source AI agents such as OpenClaw, whose recent rise in popularity has coincided with heightened market volatility around software-as-a-service firms.
The broader context is strategic. Marc Einstein, research director at Counterpoint Research, noted that AI companies are preparing for the possibility that autonomous agents could disrupt traditional internet business models. If agent systems reduce reliance on conventional SaaS platforms, incumbents across sectors could face structural change. In that sense, Alibaba’s rapid iteration signals both defensive and offensive positioning.
Qwen3.5 also expands language support to 201 languages and dialects, up from 82 in the prior generation—a move analysts interpret as aligning with Alibaba’s global ambitions. Further open-weight releases are expected during the holiday period, according to Alibaba Cloud’s Qwen technical lead.
The launch comes as U.S. firms accelerate their own agent development cycles. Sam Altman recently announced that OpenClaw’s creator would join OpenAI, while DeepMind’s Demis Hassabis suggested Chinese AI systems trail Western counterparts by only months.
If so, the Qwen3.5 rollout underscores a narrowing gap—and an increasingly global race shaped by deployment, ecosystem integration, and model capability.
