TaglineBlazing-fast, pay-as-you-go inference API for open-source LLMs and multimodal models, now plugged directly into the Hugging Face ecosystem.AI search done right. Cited answers, not chat theater.One API, every model. Pay-as-you-go, no subscriptions.Run any open-source AI model with an API call.

PricingFree $5 credit on signup, then pay-as-you-go from $0.06/M tokensFree + $20/mo ProPay per token — model-dependentPay per second of compute
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.Replacing Google for any question where you want a cited answer in seconds.Developers experimenting across models. Apps that want fallback logic.Developers using open-source models (Flux, SDXL, Whisper, etc).
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
  • Sources every claim
  • Fast, current answers
  • Pro Search runs multi-step research
  • Spaces for persistent context
  • 300+ models from one endpoint
  • Automatic fallbacks between providers
  • No subscription — just pay what you use
  • Tens of thousands of models (image, video, audio, LLMs)
  • One-line API for any model
  • Cog framework for custom model deploy
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
  • Not a general chatbot
  • Answers can be shallow on complex topics
  • Slight markup over direct API
  • Some provider features not exposed
  • Cold starts on less-popular models
  • Pricing gets real at scale
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.)S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.S-tier for model-shopping. I use this for every prototype before committing.S-tier for open-source model APIs. The default in this space.
