Amazon releases its own Jev clone as decision models flood the web
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.

The model is fully open-sourced, available now, and small enough to run locally. Amazon distinguished engineer Marc Brooker came up with the project after seeing Jev and trying to build his own take on such a model.
