Frequently Asked Questions

What prices does ComputeUnion compare?

ComputeUnion currently tracks 5,808+ AI model prices across official APIs and relay providers, plus hourly GPU rental offers.

What is the difference between official API and relay pricing?

Official APIs come directly from model developers. Relays may offer lower prices or different payment options, but latency, SLA, data handling, and support can differ.

How often are prices updated?

Platforms with machine-readable pricing endpoints are auto-scraped. Other prices are maintained from official pricing pages, with update or maintenance status shown on the site.

When should I rent a GPU instead of buying an AI API?

APIs often fit fixed-model and lower-volume usage. GPU rental is worth comparing for self-hosting, sustained workloads, fine-tuning, or full control over model deployment.
