Pros & Cons

Kagi FastGPT

  • Genuinely useful building block for developers avoiding a custom multi-step RAG pipeline
  • Leverages Kagi’s ad-free search infrastructure as a grounded retrieval layer

  • No fixed public pricing tiers — requires contacting Kagi directly for a custom quote
  • Separate product and billing from the consumer Kagi search subscription
  • Best suited to developers with API integration needs rather than individual searchers
