Amazon releases Strands Decider 2B open source decision model
Amazon Web Services has released Strands Decider 2B, an open source decision model inspired by TypeSafe's Jev, designed to provide fast, low-cost, calibrated choices for agentic workflows. The model, built on the Qwen3.5-2B LLM torso, outputs a decision with a confidence score rather than generating text, making it suitable for automation tasks that don't require full LLM capability. AWS distinguished engineer Marc Brooker initiated the project after experimenting with his own implementation. The model is available now and can run locally. TypeSafe CEO Diogo Almeida commented on the competitive landscape, noting the difficulty of making such models truly intelligent.
