Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Langfuse

  • Free Hobby plan limited to 2 users and 30-day data retention
  • Overage pricing applies beyond included units; graduated rates from $8.00 per 100k units down to $6.00 per 100k units at 50M+ volume

PyTorch

  • Dynamic computation graph can be less efficient for production inference than static graphs
  • Requires more manual code for distributed training compared to some alternatives
  • Documentation focused heavily on research use cases rather than production deployment
