Weaknesses

  • Model breadth (77 tracked) lags behind aggregators like OpenRouter or Replicate for niche or newly-released models
  • No free tier beyond the $5 signup credit; requires a card or prepayment to continue
  • Bot-joining model
  • Team features gated
Kai's verdictS-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.A-tier. The most interesting spreadsheet in years. Great for ops dashboards.DeepInfra is the quiet workhorse of the inference API space — serious price performance on H100s, a genuinely clean OpenAI-compatible API, and now a native HF provider makes it a strong default choice for any team running open-source models at scale. (Verdict pending Phi's full review.)S-tier for solo + free. The best free option, hands down.
