Qwen3.5-35B-A3B is the breakout model of the Qwen3.5 Medium Series and arguably the biggest efficiency breakthrough in recent open-source AI. Despite having only 3B active parameters per token (8.6% of total), it outperforms the previous generation’s 235B model on most benchmarks, as well as GPT-5 mini and Claude Sonnet 4.5 on knowledge (MMMLU) and visual reasoning (MMMU-Pro). It runs on an 8GB GPU and supports 256K context natively.
