Qwen3.6-35B-A3B is a Mixture-of-Experts open-source model with 35B total parameters but only ~3B active per request, making it highly efficient. It features a 262K context window (extendable to 1M with YaRN), multimodal support (text, image, video), and an Apache 2.0 license. The model is designed for agentic coding workflows, achieving top scores on SWE-bench Verified (73.4), Terminal-Bench 2.0 (51.5), and strong STEM reasoning benchmarks. Key architectural innovations include Gated DeltaNet linear attention and Grouped Query Attention (GQA). It supports a switchable thinking/non-thinking mode and a new thinking preservation feature that reuses reasoning across conversation turns. Deployment is supported via vLLM, SGLang, KTransformers, and Hugging Face.
