The 140x Shrink: When Python's AI Inference Tax Became Optional
The LocalAI team just published something that should make every infrastructure team question their deployment pipeline. vllm.cpp, their C++20 port of vLLM's V1 serving architecture, ships as a 66 MiB binary against vLLM's 9.1 GiB virtualenv — a 140× reduction in install footprint — while matching vLLM's throughput token-for-token on Qwen3.6-27B across every concurrency level measured. Peak host memory drops from 28.18 GiB to 24.88 GiB. The output is identical. No Python, no PyTorch, no bundled CUDA userspace, no…
