We post-trained
@Alibaba_Qwen's Qwen3.5 2B to build THIS / THAT Model 1.2, our open-source decision model, specialised for decision-making, routing, classification, and scoring.
It scores higher than every hosted model we tested across 1,710 decisions and responds in 31.4 ms. That’s around 32x faster than Claude Opus 5.
Training specialised models for specific business needs will become the norm.
