I'm building a prototype with an open-source model - what's the easiest way to host it?

The easiest way is usually to pick the hosting path that matches how “prototype-y” you want it to be:

Fastest/easiest options

1) Managed model APIs / hosted inference

If your open-source model is available through a provider that hosts it for you, this is the simplest:

• Pros: no infra, autoscaling, easy auth/logging
• Cons: less control, can be pricier, model availability may vary

Good if you just want to test the product idea quickly.

2) Hugging Face Inference Endpoints

Great middle ground for open-source models.

• Pros: very easy deployment, handles GPU infra, production-friendly
• Cons: costs more than self-hosting, some setup required

If your model is on Hugging Face, this is often the quickest “real deployment” route.

3) Run it yourself on a small cloud VM

Best for maximum flexibility and low complexity if traffic is low.

• Use a single GPU VM on:

  • AWS / GCP / Azure
  • RunPod
  • Vast.ai
  • Lambda Labs

• Serve with:

  • vLLM (great for LLMs)
  • TGI (Text Generation Inference)
  • Ollama (super easy for local/prototype use)
  • LM Studio (local/testing)

• Pros: cheap-ish at small scale, full control

• Cons: you manage uptime, scaling, updates

4) Container platforms

If you already have Docker:

• Google Cloud Run (works well for smaller CPU models)

• Fly.io

• Railway

• Render

• Pros: simple deployment

• Cons: GPU support may be limited or awkward for bigger models

My practical recommendation

For a prototype:

• Local/dev: use Ollama or vLLM
• Public demo / lightweight production: use Hugging Face Inference Endpoints
• Lowest cost with control: a single GPU VM + vLLM

If you want the absolute easiest setup

Ollama is probably the easiest if the model fits your hardware:

1. install Ollama
2. pull the model
3. expose an HTTP API
4. point your app at it

Example:

ollama serve
ollama pull llama3.1

Then your app can call the local API.

Quick decision guide

• Need it live today? Hugging Face Inference Endpoints
• Need cheapest prototype? Single GPU VM with vLLM
• Need local dev simplicity? Ollama
• Need zero infra? Managed hosted API

If you tell me:

1. which model you’re using,
2. whether it needs a GPU,
3. expected traffic,
4. whether this is just internal or public,

…I can recommend the best exact hosting option.
