Alibaba Qwen3.8 Open Sources 2.4 Trillion Parameters: Claiming Strongest Model After Fable 5 as Chinese Open-Source Models Surge

Alibaba has announced the launch of the open-source Qwen3.8-Max model, boasting 2.4 trillion parameters and claiming to be the strongest model after Anthropic Claude Fable 5. The model is deployed on the TokenPlan and Qoder platforms with preview access, and full weights will be released under an open-source license. This announcement marks the culmination of an extraordinary month for Chinese open-source AI, with four major labs launching trillion-parameter models within weeks. Alibaba's strategy differs by integrating Qwen3.8 directly into its tools, creating ecosystem lock-in that standalone model releases cannot achieve.
