Alibaba's AI team Qwen has released the open model weights for Qwen3.8. The core model, Qwen3.8-27B, is a multimodal dense model with 27 billion parameters that, according to Qwen, outperforms the larger Qwen3.7-Plus in coding and office tasks. The team also touts improved agent capabilities, with the model planning more independently and completing tasks more reliably. It natively handles up to 262,000 tokens of context and can scale to one million using the YaRN method. Beyond text, it processes images and videos, including diagrams, documents, and multi-hour video. A flexible thinking mode is on by default but can be toggled per query.

Both models are available on Hugging Face and ModelScope. A hosted version with one million tokens of context will soon be available through Qwen Cloud, Alibaba's AI service.
