Small experiments Valentin Galfré builds to see what a new tool can do, each one live on its own page.

- [Jev directs a shader](https://galfrevn.com/labs/jev/shader): A pixel-art weather shader whose uniforms are set by a decision model. The text you type becomes three probabilities every 350 ms.
- [Jev()](https://galfrevn.com/labs/jev/filter): Filter and rank any array with a plain English sentence. One call per row, a probability back, no embeddings.
- [Jev moves a crowd](https://galfrevn.com/labs/jev/crowd): A plaza with a thousand strangers. Type what just happened and a decision model decides, one call per person, who runs and who helps.
- [Jev plays truco](https://galfrevn.com/labs/jev/truco): A game of truco to 15 points against a decision model. Every card it plays and every envido it sings is one call with the legal moves as options.
