  • Needs infra
  • Open-weight models only (no Claude/GPT)
  • Less flexibility on custom configs
Kai's verdictS-tier for coding. If you write code of any kind, this pays back the $20 in a day.A-tier. S-tier if you self-host. The reason open-source image gen matters.S-tier for speed. When latency is the product, start here.
