# AWS debuts Strands Decider 2B, a first lightweight decision model for accelerate agentic workflows

## Retrieval answer

AWS has released Strands Decider 2B as open source, a 2-billion-parameter decision model intended to select among predefined choices rather than generate text.

AWS has released Strands Decider 2B as open source, a 2-billion-parameter decision model intended to select among predefined choices rather than generate text. SiliconANGLE reports that it is built on a Qwen3.5-2B base with a customized pointer head and is designed for local deployment as well as cloud environments. AWS says it can run locally with latency below 150 milliseconds and reports high accuracy and calibration on JevBench compared with other open-source 2B models. The model is available on Hugging Face; AWS also published its codebase, training scripts and examples on GitHub. The report describes potential uses including model routing, tool selection, context management, guardrail enforcement and policy classification. These benchmark and latency claims are attributed to AWS; the supplied source does not provide independent validation.
