  • Weaker at coding than rivals
  • Smaller app/API ecosystem
  • Concerns over bias and tone
  • Limited voice mode

Kimi

A polished consumer assistant whose underlying Kimi K2 model ships as open weights you can self-host.

  • Built on open-weight Kimi K2 models
  • Agent mode with parallel subagents
  • Free tier available
  • China-based, data-residency concerns
  • English UX less polished than rivals
