PricingFree $5 credit on signup, then pay-as-you-go from $0.06/M tokensFree + $10-$19/user/mo$10/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.Sales teams, customer success, anyone running many discovery calls.Knowledge workers + thinkers who want AI in their second brain.
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
  • Good CRM integrations (Salesforce, HubSpot)
  • Talk-time + sentiment analytics
  • Call scoring
  • AI auto-links related notes
  • Generates backlinks + summaries
  • Clean, minimal UX
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
  • Bot-joins (intrusive)
  • Gets expensive at team scale
  • Expensive for just notes
  • Smaller community than Obsidian
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 for sales teams. B-tier for solo users.A-tier. Niche but beloved. If you've outgrown Notion, try this.
