Alibaba's Qwen team has released the Qwen 3.5 family of open weight models. Junyang Lin, the lead researcher, announced his departure from the team via Twitter.

Key figures from Alibaba's Qwen AI team, known for their extensive contributions to open source generative models, have departed following the release of the Qwen3.5 small model series. The release received public acclaim from Elon Musk for its notable intelligence density.

Qwen3-Coder-Next is an open-weight language model designed for coding agents and local development, built on the Qwen3-Next-80B-A3B backbone. It features a sparse Mixture-of-Experts (MoE) architecture with 80 billion total parameters, activating only 3 billion parameters per token to optimize performance and reduce inference costs.
