  • 500+ tokens/sec on Llama/Mixtral — feels instant
  • Custom LPU hardware
  • Great free tier
  • Works like an engineer — takes Slack tasks, opens PRs
  • Handles multi-hour engineering work
  • Reports back with what it did
Weaknesses
  • Developer-only
  • You build the UI
  • Aesthetic ceiling below Midjourney
  • Less style variety
  • Open-weight models only (no Claude/GPT)
  • Less flexibility on custom configs

  • Not for solo hobbyists
Kai's verdictS-tier for builders. The right primitives. What Kai is built on under the hood.S-tier for text-in-image. Use this for posters, Midjourney for art.S-tier for speed. When latency is the product, start here.A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.
