PricingFree $5 credit on signup, then pay-as-you-go from $0.06/M tokensFree + $12/moFree + $20/mo Pro + $40/mo BusinessFree + $28+/user/mo
Best forBackend developers and ML engineers who want the cheapest reliable inference for open-weight LLMs in production, especially those already living inside the Hugging Face ecosystem.Essays, long-form drafts, thinking on the page.Developers. Non-developers who want to ship working code.Data teams at startups + enterprises.
Strengths
  • Among the cheapest per-token rates for open-source models — consistently undercuts Together AI and Fireworks on small models
  • OpenAI-compatible API means zero migration headache from existing stacks
  • Now a first-class Hugging Face Inference Provider, so HF-native workflows (SDKs, Playground, agent harnesses) get DeepInfra with a one-line swap
  • Runs on H100/A100 and NVIDIA Blackwell GPUs with auto-scaling and 99.982% uptime SLA on dedicated tier
  • Supports LoRA adapter deployments and private custom model hosting, not just public models
  • Clean writing UX — distraction-free
  • +++ prompt triggers AI help
  • Collaboration + AI feedback together
  • Tab completion feels like mind-reading
  • Composer for multi-file edits
  • Runs Claude, GPT, Gemini — you pick
  • SQL + Python + no-code in one notebook
  • Magic AI writes queries + viz for you
  • Team-grade collaboration
Weaknesses
  • Primarily developer/API-first — no meaningful consumer-facing product or chat UI to speak of
  • 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
  • Less feature-rich than Google Docs
  • AI ceiling below dedicated tools
  • Can feel overwhelming for non-coders
  • Expensive at scale
  • Overkill for casual users
  • Enterprise pricing
Kai's verdictDeepInfra 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.)A-tier. Beautiful UX. The writing app I'd pick if I only wrote long-form.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.A-tier for data teams. S-tier if you already live in SQL + Python.
