Qwen3-Reranker as a game mechanic: combat driven by semantic scores

We're working on a crafting / battling game focusing on using semantic similarities called Entropedia: https://entropedia.xyz

The players craft cards from simple concepts and during the battles they have to find a cards that is the closest to a given target, like "better when wet".

I use Qwen3-Reranker to score the cards as an heuristic for my CPU opponents. It's cheap, fast and deterministic.

Happy to share more details if you're interested!
