PricingFree $5 credit on signup, then pay-as-you-go from $0.06/M tokensPay per second of computeFree + $8/mo + $20/mo + $60/moIncluded with ChatGPT Pro $200/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.Developers using open-source models (Flux, SDXL, Whisper, etc).Anything with text — posters, ads, album covers, slide decks.Power users willing to pay $200/mo for a browser bot.
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
  • Tens of thousands of models (image, video, audio, LLMs)
  • One-line API for any model
  • Cog framework for custom model deploy
  • Best text rendering in the game
  • Strong free tier
  • Good for logos, posters, thumbnails
  • Actually uses websites — fills forms, clicks, checks out
  • Built into ChatGPT
  • Good for repetitive web tasks
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
  • Cold starts on less-popular models
  • Pricing gets real at scale
  • Aesthetic ceiling below Midjourney
  • Less style variety
  • Slow vs doing it yourself
  • Breaks on complex auth flows
  • $200/mo gate
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 open-source model APIs. The default in this space.S-tier for text-in-image. Use this for posters, Midjourney for art.B-tier. Still early. Manus is more flexible for less money.
