Frequently Asked Questions
How to Choose
Compare total cost of ownership
Look beyond the free software cost to include hardware, hosting, maintenance, and developer time needed to deploy and manage the solution yourself.
Evaluate ease of local setup
Check documentation, community support, and available guides for installation on your preferred hardware or infrastructure, especially if you lack DevOps expertise.
Check integration ecosystem
Verify what existing tools, libraries, and platforms the framework or model works with, and whether it supports common deployment targets like Docker or Kubernetes.
Assess model performance fit
Compare model size, speed, accuracy, and memory requirements against your actual use case—smaller models run faster locally but may sacrifice quality.
