- This is a library meant to be used from code. It is not a standalone app.
- Does vLLM work on a phone?
- No. It needs a computer.
- Can I use vLLM commercially?
- The licence is Apache-2.0, which permits commercial use. Conditions such as keeping the copyright notice still apply, so read the licence text before shipping it inside something.
