Cons

Pricing

  • Free tierYes
  • LicenceApache-2.0
  • Self-hostYes, source is public
  • Public price listNot published

vLLM does not publish a web price list. For consumer apps that usually means pricing appears inside the product; for enterprise tools it means talking to sales. Why we do this
