Ollaya Runs Jev-Style Decision Models Locally
A new execution app called Ollaya runs Jev-style decision models on local hardware. Jev, which appeared on September 15, 2026, is an AI model that outputs judgments and confidence scores for multiple options. Ollaya supports Windows, macOS, and Linux, and is published as open source under Apache License Version 2.0. In a listed example, the decision model Winnow-E4B reads a user message about a third double charge and returns Intent: refund request (91%), Urgency: present (92%), and Anger level: 2.89 (86%). A chart comparing Jev's API service against a local run on a GeForce RTX 4070 shows that, depending on the model, local accuracy gets fairly close to Jev's while latency is shorter. Ollama added decision-model support in version 0.35, but that release covers three models, nimble, tev1, and tev1:0.8b, and allows a maximum of 15 options per request. Ollaya can run higher-performance models and set up to 255 options.
