TaglineAI-powered networked notes. Roam with a brain.Blazing-fast, pay-as-you-go inference API for open-source LLMs and multimodal models, now plugged directly into the Hugging Face ecosystem.Chinese open-weight powerhouse. Crazy cheap, genuinely smart.The one that actually gets text in images right.

Pricing$10/moFree $5 credit on signup, then pay-as-you-go from $0.06/M tokensFree web + ultra-cheap API (~$0.14/M input tokens)Free + $8/mo + $20/mo + $60/mo
Best forKnowledge workers + thinkers who want AI in their second brain.Backend 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 + cost-conscious builders. Anyone fine with self-hosting.Anything with text — posters, ads, album covers, slide decks.
Strengths
  • AI auto-links related notes
  • Generates backlinks + summaries
  • Clean, minimal UX
  • 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
  • Open weights you can self-host
  • Strong reasoning + math
  • Near-free API pricing
  • DeepSeek-V3 / R1 are serious models
  • Best text rendering in the game
  • Strong free tier
  • Good for logos, posters, thumbnails
Weaknesses
  • Expensive for just notes
  • Smaller community than Obsidian
  • 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
  • Data goes to servers in China — privacy concerns for business use
  • Chinese policy filters
  • English polish trails Western models
  • Aesthetic ceiling below Midjourney
  • Less style variety
Kai's verdictA-tier. Niche but beloved. If you've outgrown Notion, try this.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 price/performance. A-tier for consumer use. If you build apps, this is the budget pick.S-tier for text-in-image. Use this for posters, Midjourney for art.
