Pros
  • Fully open-source under Apache 2.0 with no usage limits
  • Strong stacked-ensemble baselines with minimal code
  • First-class R, Python, and GUI interfaces
  • Scales from laptop to Hadoop/Spark/Kubernetes clusters
  • MOJO/POJO export for low-latency production deployment
  • Wide open-model catalogue
  • Competitive inference pricing
  • Fine-tune + serve in one place
  • Dedicated endpoints for production
Cons
  • Focused on tabular data, not LLMs or unstructured inputs
  • JVM-based runtime can be heavy to operate
  • Documentation assumes existing ML literacy
  • Latency varies by model
  • Less polish than OpenAI
