Description
WaterSheep answers yes/no, choice, rating and multi-label questions about text, with a probability for every option. It takes Jev's API requests, so TypeSafe's own Python SDK works with it after a one-line change. Open weights, Apache 2.0, free.

Could you build this?
Partial Providing a drop-in API wrapper is simple, but producing an open-weights model with calibrated probability outputs across varied classification tasks requires ML training expertise.
What it would actually take: Requires fine-tuning a base language model (such as DeBERTa or a small Llama model) on zero-shot and NLI classification benchmarks, combined with calibration techniques (like temperature scaling) so output logits map accurately to real probabilities. The model must then be packaged into an optimized inference server (vLLM or ONNX Runtime) exposing the compatible SDK interface.
