Alibaba’s Qwen 3.5: 397B-Parameter Agentic AI Model Challenging Rivals
Alibaba Cloud launched on February 16, 2026 its Qwen 3.5, a new generation of large language models (LLMs) specifically designed for the agentic AI era - systems capable of executing complex tasks independently with minimal human supervision.
Model in Two Versions
Alibaba made Qwen 3.5 available in two versions:
- Open-weight version: 397 billion parameters, available for download, local execution, fine-tuning, and deployment on own infrastructure
- Hosted version (Qwen-3.5-Plus): Version hosted on Alibaba’s cloud platform Model Studio
Both were released on the eve of Chinese New Year (February 17, 2026), just a week after Alibaba released an AI model designed for robots.
Key Features
Focus on Agentic AI
The model was built with new coding and agentic capabilities, being compatible with open-source AI agents like those from OpenClaw, which have recently surged in popularity.
AI agents are systems that can independently take actions and complete multi-step tasks on a user’s behalf. The potential for these agents to replace the work of software as a service companies has rocked markets.
Native Multimodality
Qwen 3.5 comes with native multimodal capabilities, enabling the model to understand text, images, and video simultaneously within a single system.
Support for 201 Languages
A significant expansion from the previous generation (which supported 82 languages), Qwen 3.5 now offers support for 201 languages and dialects, reflecting Alibaba’s global ambitions.
Benchmarks and Competitiveness
Alibaba released benchmark tests showing that Qwen 3.5’s performance is on par with leading models from OpenAI, Anthropic, and Google DeepMind, though these comparisons are self-reported and not independently verified.
The hosted version Qwen-3.5-Plus also demonstrated performance on par with leading competitors, according to the company.
Market Context
The launch of Qwen 3.5 comes at a time of intensifying competition in China’s AI space, with several models launched in the past week.
Local competitors like ByteDance and Zhipu AI have also released upgraded models recently, all aimed at supporting more agent capabilities.
Marc Einstein, research director at Counterpoint Research, told CNBC that artificial intelligence companies are preparing for the possibility that AI agents could “upend traditional internet business models.”
“If this happens, consequences for those who are not prepared will be severe and Chinese AI companies are aware of this,” he said.
The 397-billion-parameter open-weight model is smaller than its previous flagship model, but the company said the latest model showed significant improvement based on self-reported benchmark evaluations.
The company is expected to release more open-weight models during Chinese New Year, Lin Junyang, technical lead of Alibaba Cloud’s Qwen team said in a social media post.
