Where each one falls short

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

Pika

  • Maximum video length of 3-8 seconds per generation, requiring multiple renders for longer content
  • Inconsistent output quality with character morphing, distortion, and temporal inconsistencies like flickering textures
  • Poor handling of complex scenes with multiple characters showing body distortions and weak character consistency across frames
  • No native audio generation, requiring separate tools to add sound to silent videos
  • Customer service and billing issues with complaints of non-responsive support and confusing billing practices

Ray

  • Windows support is beta and multi node Ray clusters are untested on Windows
  • Windows lacks copy on write forking, which raises memory requirements, and Ray code assumes UNIX filenames
  • Multi node clusters are untested on Apple Silicon Macs
  • The Java API is experimental and community supported only, and requires matching Java and Python versions
  • Python 3.13 support is beta
