TaglineBlazing-fast, pay-as-you-go inference API for open-source LLMs and multimodal models, now plugged directly into the Hugging Face ecosystem.Edit video + podcasts by editing the transcript.Build a full app from a prompt. Stripe-ready.Run any open-source AI model with an API call.
CategoryDev PlatformVideoDesignDev Platform
PricingFree $5 credit on signup, then pay-as-you-go from $0.06/M tokensFree + $16-$50/moFree + $25-$100/moPay 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.Podcasters, course creators, anyone editing talking-head content.Non-devs + solopreneurs shipping MVPs.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
  • Edit audio/video by deleting text
  • Overdub (voice clone) for fixes
  • Strong collaboration + remote recording
  • Generates full apps + DB + auth
  • Good for non-developers
  • Ships faster than hand-coding
  • 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 traditional NLE — some workflows awkward
  • Overdub ethics require care
  • Complexity ceiling
  • Can generate brittle code
  • 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 content creators. Cuts editing time in half. Non-obvious but life-changing.A-tier. The strongest 'no-code' AI builder right now. Great for founder MVPs.S-tier for open-source model APIs. The default in this space.
