Amazon Web Services released an open-source decision model inspired by TypeSafe’s Jev , with AI developers increasingly seeking intelligence that is more suited to computer automation than frontier LLMs.

Amazon’s Strands Decider 2B, released the same week OpenAI announced a similar offering , is a high-speed, low-cost way to sort between pre-decided options and deliver a measure of how confident it is in its choice. The model is fully open-sourced, available now, and small enough to run locally.

“What originally piqued my interest in this class of models was that they make a perfect decider for a workflow step— ‘what is the next thing for me to do here, based on where I am?’” Brooker told TechCrunch. He said it offers customers “a workflow step that can be structured in a way that is more reliable, thanks to the confidence scores, thanks to the closed domain of answers, [and is] lower latency, potentially lower cost.”
