⚡ Introducing ZooWork Instinct Tuned 4B — an open decision model Instead of generating text, Instinct scores candidate logits in one forward pass and returns temperature-scaled probabilities for choice, noul, and ordinal score questions. 🎯 4B parameters based on Qwen3.5-4B 📊 198/231 (85.71%) on the published JevBench tasks ⚡ Decode-free, single-order decision inference 📜 Apache-2.0 open weights
💻 Open-source runtime: https://github.com/SerendipityOneInc/instinct 🌐 Hosted API: https://instinct.zoowork.ai/ The published JevBench tasks were used during development, so the result is a transparent public-set reference—not a held-out claim. Feedback on domain transfer, calibration, and option-order sensitivity is very welcome. 🚀
