Quick recommendation
GPU instances, serverless functions, and edge deployments — hosting for AI-native products.
Hosting Options for AI-Native Products
1. Vercel — Serverless AI API Wrappers
Use for: hosting Next.js AI applications with serverless functions that call OpenAI, Claude, or other AI APIs. Edge Functions run close to users for minimal latency. Generous free tier (100GB bandwidth, 100GB-Hrs execution). Best for AI SaaS products that wrap third-party APIs.
2. Cloudflare Workers — Edge AI Inference
Use for: running AI inference at the edge with Workers AI. Cloudflare's global network runs models like Llama and Stable Diffusion on GPUs in 300+ cities. No cold starts, pay-per-use pricing. Best for AI features that need to be fast and globally available.
3. Replicate — GPU Cloud for ML Models
Use for: running open-source ML models without managing GPU infrastructure. Replicate provides one-click deployment for thousands of models (Stable Diffusion, Whisper, Llama). Pay only for GPU seconds used. Best for AI products that need custom model inference.
4. Hugging Face Spaces — Free ML Demo Hosting
Use for: hosting ML model demos and prototypes for free. Hugging Face Spaces provides free CPU hosting and affordable GPU upgrades. Best for showcasing AI models, building community, and testing before scaling to production.
5. Railway — Full-Stack AI App Platform
Use for: deploying full-stack AI applications with databases, background workers, and GPU support. Railway's template marketplace includes pre-configured AI stacks (LangChain, OpenAI, vector DBs). $5/mo starter credit included.

How to choose for AI tool builders
API-first or model-first?
If you're wrapping OpenAI/Claude APIs, use Vercel or Cloudflare — no GPUs needed. If you're running your own models, start with Replicate to avoid managing infrastructure, then consider dedicated GPU instances at scale.
Watch cold start times
Serverless GPU functions can have 10-30 second cold starts. If your users expect instant responses, use Cloudflare Workers AI (no cold starts) or keep a minimum number of warm instances running.
Start with free tiers
Vercel, Cloudflare, Hugging Face, and Railway all have generous free tiers. Build and validate your AI product before committing to paid GPU infrastructure. You can always scale up when you have paying users.
