The vLLM Lie: Why 24x Faster Doesn't Apply To You
THE vLLM LIE: WHY 24X FASTER DOESN'T APPLY TO YOU
A Reddit user finally asked the question nobody else would — is vLLM actually worth it if you aren't serving the model to anyone else? The honest answer breaks an entire corner of the local AI internet.
In this episode:
Where the 24x throughput number actually comes from (it's not your desk)
Why Ollama ties or beats vLLM at batch size 1, according to Red Hat's own benchmarks
The Apple Silicon problem nobody warns Mac users about
The one case where vLLM IS the right call, even for a solo developer
A concrete watch-list for vLLM Metal, llama.cpp continuous batching, and your own usage pattern
