vLLM 0.8.5 Maxes Out Flexibility with Lightweight CPU Install

The vLLM team dropped v0.8.5 with a one-liner install option, stripping out the heavy CUDA dependency for CPU-only dev setups. This is a big deal for anyone wanting to hack on LLM serving without renting a GPU cloud instance just to spin up a test environment.

Inside the Muon Optimizer: Chasing GPT-4 Level Performance for Less

This paper breaks down Muon, an optimizer that achieves GPT-4 level performance with significantly less compute during pretraining. It’s the kind of efficiency math that makes training custom small models on a budget actually viable.
