Jev TypeSafe alternatives

Jev TypeSafe is a hosted decision API that returns typed choice labels, ordered scores and yes/no probabilities, so application code can branch on the results. When choosing among these alternatives, consider whether you need per-answer probabilities, multi-question requests, a browser playground, self-hosting, or a model trained on your own labeled examples. Pricing is similar for most of the direct alternatives.
