The Story of Qwen: Alibaba’s AI Models From 7B to 2.4T
MarkTechPost 1 week ago 22
Alibaba’s Qwen model line evolved from an invite-only Tongyi Qianwen enterprise chatbot beta into open-weight releases that reached 2.4 trillion parameters. The Qwen3.8 release open-sourced Qwen3.8-2.4T-A95B with 2.4 trillion parameters and 95B active parameters on August 12, 2025. As Qwen grew, Alibaba shifted from mostly restrictive licensing to broader openness for smaller models, while making larger “Plus/Max” tiers proprietary and moving some revenue-based models to a two-tier split.
