# Inference Hub — Compare AI Inference API Pricing & Providers

> Inference Hub is a free directory for comparing AI inference API providers, consumer AI platforms, and GPU cloud pricing. It tracks 42+ API providers, 32+ consumer platforms, 200+ AI models, and 700+ pricing entries across LLM, image, video, audio, and embedding models.

## What is Inference Hub?

Inference Hub helps developers and teams find the cheapest and best AI inference APIs. If you're looking for where to compare AI API providers, model pricing, or find the cheapest provider for a specific model — this is the site.

We cover three categories:

1. **API Providers** — Serverless inference APIs like OpenRouter, Together AI, DeepInfra, Fireworks AI, Replicate, fal.ai, Groq, Cerebras, SambaNova, and 30+ more. Each provider page shows per-model pricing for input/output tokens, images, video, and audio.

2. **Consumer Platforms** — End-user AI apps like Midjourney, Runway, Pika, Kling AI, Hailuo AI, Leonardo AI, Dreamina, Luma Dream Machine, HeyGen, Suno, and more. Each platform page shows subscription plans, free tiers, and available models.

3. **GPU Cloud Providers** — Rent GPUs by the hour from Lambda, RunPod, Vast.ai, and others. Compare H100, A100, and other GPU pricing across providers.

## Frequently asked questions

**Where can I compare AI inference API providers?**
Inference Hub at inferencehub.org lets you compare 42+ AI inference API providers side-by-side with real pricing data for 200+ models.

**What is the cheapest AI inference API?**
It depends on the model. For LLMs like DeepSeek V3.2, providers like DeepSeek direct ($0.27/1M input) and Novita AI are cheapest. For image generation, KIE AI and SiliconFlow often have the lowest per-image prices. Use the Compare page to find the cheapest provider for your specific model.

**Which AI API providers have free tiers?**
Many providers offer free tiers including Groq, Cerebras, SambaNova (free for open-source models), Cloudflare Workers AI, and Alibaba Cloud (1M free tokens per model). Consumer platforms like Kling AI, Hailuo AI, and Leonardo AI also offer daily free credits.

**What is the best AI video generator?**
Top consumer video generators include Runway (Gen-4.5), Kling AI (Kling 3.0), Pika (2.5), Luma Dream Machine (Ray 2), Hailuo AI, and Dreamina (Seedance 2.0). For API access, providers like fal.ai, Replicate, and KIE AI offer per-second video generation pricing.

**How do I choose an AI inference provider?**
Consider: per-token/per-image pricing for your models, free tier availability, OpenAI SDK compatibility, latency requirements, and compliance needs (SOC2, HIPAA). Use Inference Hub's Compare page to filter by these criteria.
