main entity: Can I use Ollama or Jan to build AI applications?
  type: Question
  accepted answer: Answer
    text: Ollama is purpose-built for developers and offers a native OpenAI-compatible REST API, making it ideal for integrating local LLMs into applications. Jan lacks native API capabilities and is designed primarily for end-user interaction through its chat interface, though some third-party integrations exist.
    language: en-US
main entity: Which tool uses less system resources?
  type: Question
  accepted answer: Answer
    text: Ollama is significantly more lightweight, requiring as little as 4GB RAM and a ~150MB installation, making it suitable for older machines or resource-constrained environments. Jan requires a minimum of 8GB RAM and a larger installation footprint (~300MB+), though it provides a more polished user experience at the cost of resources.
    language: en-US
main entity: Do both tools support the same LLMs?
  type: Question
  accepted answer: Answer
    text: Both support popular open-source models like Llama 2 and Mistral. Ollama supports 100+ models through its registry, while Jan supports 50+ models with automatic downloads. Model availability differs slightly between platforms, but they have significant overlap in popular options.
    language: en-US
main entity: Is either tool suitable for beginners?
  type: Question
  accepted answer: Answer
    text: Jan is far more beginner-friendly with its visual interface, model browser, and one-click setup. Ollama requires terminal/command-line proficiency and manual model management via CLI commands, making it less accessible to non-technical users without prior Linux/command-line experience.
    language: en-US
main entity: Can I run both Ollama and Jan on the same machine?
  type: Question
  accepted answer: Answer
    text: Yes, both tools can coexist on the same system since they have separate installations and configurations. However, running both simultaneously with heavy model loads would require significant RAM (16GB+ recommended), so most users would choose one or the other for a single machine.
