The short version

  • Each has a real cost: Pika maximum video length of 3-8 seconds per generation, requiring multiple renders for longer content; Weka the package management system needs an internet connection to download and install packages, so an air-gapped install gets only the core distribution
  • They diverge on capability: Pika covers Text-to-video, Weka covers Classification.
  • Prices and features above were last checked on 30 August 2026.

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

Weka

  • The package management system needs an internet connection to download and install packages, so an air-gapped install gets only the core distribution
  • Weka is split into a stable 3.8 branch that receives only bug fixes and compatibility-safe upgrades and a 3.9 development branch that may receive features that break compatibility
  • Weka requires a 64-bit Java VM; the bundled installers ship Bellsoft OpenJDK 25 per platform and architecture
