Jan v1: Advanced Agentic Language Model Overview Jan v1 is the first release in the Jan Family , designed for agentic reasoning and problem solving within the Jan App. Based on our Lucy model, Jan v1 achieves improved performance through model scaling. Jan v1 uses the Qwen3 4B thinking model to provide enhanced reasoning capabilities and tool utilization. This architecture delivers better performance on complex agentic tasks. Performance Question Answering (SimpleQA) For question answering, Jan v1 shows a significant performance gain from model scaling, achieving 91.1% accuracy. The 91.1% SimpleQA accuracy represents a significant milestone in factual question answering for models of this scale, demonstrating the effectiveness of our scaling and fine tuning approach. Chat Benchmarks These benchmarks evaluate the model's conversational and instructional capabilities.
