Alibaba launches Qwen3.5 open-weight LLM; Third Point initiates stake

Alibaba rolls out Qwen3.5 family with open-weight option

Alibaba Group launches its latest large language model series, Qwen3 — spotlighting the Qwen3.5 family — as it pushes to expand its footprint in China’s fast-moving AI sector. The company releases an open-weight Qwen3.5 that users can download, run, fine-tune and deploy on their own infrastructure, alongside a hosted Qwen-3.5-Plus running on Alibaba’s Model Studio cloud platform. Alibaba describes Qwen3.5 as combining traditional LLM functions with “advanced, dynamic reasoning” and native multimodal understanding of text, images and video within a single system.

The open-weight variant contains 397 billion parameters, fewer than Alibaba’s previous flagship, but the company reports sizable benchmark gains and claims performance comparable with leading models from OpenAI, Anthropic and Google DeepMind — a claim CNBC cannot independently verify. Qwen3.5 expands language coverage to 201 languages and dialects from 82 in the prior generation, and adds new coding and agentic capabilities that Alibaba says work with open-source agents such as OpenClaw. Lin Junyang, technical lead for the Qwen team, says more open-weight models are expected during the holiday period.

Alibaba positions the launch as both a product and platform play: the open-weight release aims to lure developers who want on-premise control and customisation, while the hosted variant targets enterprises seeking managed services and integration via Alibaba Cloud. The firm emphasises agentic features — systems that can take independent, multi-step actions with minimal supervision — which it views as key to enterprise automation and new consumer applications. Alibaba frames the Qwen3.5 family as a bridge between research-quality capabilities and commercial deployment options.

Industry scramble tightens as rivals unveil upgrades

The Qwen3.5 rollout comes amid near-simultaneous upgrades from Chinese rivals including ByteDance and Zhipu AI, and follows recent agent-tool launches from U.S. players such as Anthropic. Observers say the cadence of releases underscores a global race to commercialise agentic, multimodal and coding capabilities that could reshape enterprise workflows and some software-as-a-service functions.

Investor moves signal broader interest in Alibaba

Separately, hedge fund Third Point initiates a new stake in Alibaba as part of a broader late-2025 portfolio reshuffle that adds positions in several names, signaling activist and event-driven investors are taking fresh interest in leading Chinese tech platforms.
