UnverifiedJev's design decouples judgment from execution, allowing the main model to focus on tasks that require generative capabilities.72% similarUnverifiedJev is closer to a discriminative model than a generative model, essentially a multi-class probabilistic classifier, similar to the BERT family rather than the GPT family.72% similarUnverifiedJev is a general-purpose decision model exposed via OpenRouter that accepts only the serialized state visible to the player plus legal action IDs, selects one action from them, and cannot see the opponent's hidden information.71% similarUnverifiedThe Jev model is optimized for judgment tasks at the model training level, rather than applying prompt or parsing layer patches on top of a general-purpose model.71% similarUnverifiedJev's interaction model is built around three components: state (input context), questions (available actions), and answer (output with probabilities).68% similar
