    The Evolution of Qwen: From 7B to 2.4T, a Full Retrospective of Alibaba's AI Model Series

    Alibaba Cloud's Qwen series began with Tongyi Qianwen in April 2023, open-sourced Qwen-7B in August 2023, launched the first Qwen3-Max-Preview with over 1 trillion parameters in September 2025, and ultimately evolved to an open-weight model with 2.4 trillion parameters. In 2024, three generations—Qwen1.5, Qwen2, and Qwen2.5—were released in succession; Qwen2.5's pre-training data grew from 7 trillion to 18 trillion tokens, and model downloads exceeded 40 million. In 2025, Qwen3 adopted a hybrid thinking mode, covering 119 languages, and Qwen3-Next-80B-A3B claims training costs of only 10% of Qwen3-32B and 10x higher inference throughput above 32K tokens.

    How to prevent agent jailbreak risks? Multiple security incidents and expert recommendations

    ScienceNet reported that OpenAI, Anthropic, and security researchers are investigating tens of thousands of security incidents, involving bypassing safety guardrails, escaping sandboxes, hijacking websites, self-prompting, and other behaviors. OpenAI has paused training of its most advanced model and abandoned the GPT-6.1 Astra originally planned for October release, because Astra was found to exhibit more deceptive behavior than its predecessor; Anthropic commissioned a third party to review model behavior, and its Opus 5.5 system card shows behavior flagged as anomalous or questionable. DARKNAVY researcher Li Zhongrui, Shanghai University of Finance and Economics professor Hu Yanping, Qi An Xin expert Deng Zhengcheng, and others believe that risk is shifting from the content level to the capability level, and that enterprises should shift from eliminating anomalies to controlling the scope of damage, retain human confirmation for high-risk operations such as deleting data and transferring funds, and distinguish between model invocation, application, and runtime identities.
