why didn't they use Jev or Luna decision model? Seems odd that they used Sonnet and Strands instead of trying out of the box solutions
Strands Agents is an AWS product. They're dogfooding their own product in typical AWS fashion.
Because when Sonnet was originally chosen, Jev/Luna weren't available to choose from? The decision model movement hadn't happened yet. When they were ready to replace Sonnet, they already had their own decision model. Why use someone else's?
