Qwen 3.5 Model Family Launched Amid Alibaba Team Resignations – UBOS Tech News
Simon Willison reports that Alibaba’s AI research division has undergone a wave of resignations, raising concerns about the future of its flagship large‑language‑model project, Qwen. Despite the leadership turnover, the team managed to release the highly anticipated Qwen 3.5 model family, showcasing impressive multilingual capabilities, strong reasoning performance, and competitive benchmarks against other leading models.
The new Qwen 3.5 series includes several variants optimized for different use‑cases, from lightweight deployments to high‑throughput inference.
