Run Jev-Style Decision Models Locally with Ollama (Free)

Jev got everyone talking about decision models, but its API needs credits and a credit card. Now you can run Jev-style decision models free on your own laptop with Ollama. Ollama now supports "System One" decision models: Tev1 from Together AI and Nimble from Bespoke Labs. You give them a state and a set of choices, and they return a pick with a probability and confidence score. They don't generate text, which is why output tokens cost nothing. Running locally, the cost is zero and no API key is needed. What you'll learn: - How a decision model differs from ChatGPT-style LLMs (MCQ vs essay) - Install Ollama and pull Tev1 (811 MB) or Nimble (9 GB) - Start the local server with ollama serve - Call the model from a Postman collection (jev-ollama) - Run the code demo with npm run demo local - Use confidence scores to triage flaky test failures and decide whether to retry Chapters: 0:00 Jev-Style Decision Models, Now Free on Ollama 0:51 MCQ vs Essay: How a Decision Model Works 1:33 Jev Playground: State + Choice, Score, Yes/No 2:38 Ollama Explained: Docker for AI Models 3:43 Install Ollama, Pull Tev1 & Nimble, ollama serve 5:21 Postman Collection: First Local Decision 6:57 Run the Code: npm run demo local 7:35 Zero Output Cost + Flaky Test Triage 8:42 Where to Get the Code & Other Jev Videos Resources mentioned: ⬇️ Download Ollama: https://ollama.com/download 📰 Ollama's decision models announcement: https://ollama.com/blog/ollama-now-supports-jev-style-decision-models 💻 Code + Postman collection (jev-ollama.postman_collection.json): [LINK: GitHub repo] 📘 Decision models & Jev explained: https://gauravkhurana.com/docs/AI/ai-models-concepts/#decision-models-jev Watch next (the Jev series): ▶️ Jev explained (theory, System One, Choice/Score/Noul): https://www.youtube.com/watch?v=uxME5BHvtRI ▶️ Jev hands-on demo with QA use cases: https://www.youtube.com/watch?v=qL5ytieGdhs Connect: 🎓 Courses: https://gauravkhurana.com/courses 🌐 Website: https://gauravkhurana.com 📅 1:1 mentoring: https://topmate.io/gauravkhurana #Ollama #AIForTesters #DecisionModels #SoftwareTesting #Jev
