vLLM says shipping precompiled Python bytecode in its container images cuts startup time 14–18%, about 18 seconds on an H100.

The change is a single uv flag at build time, so containers no longer recompile thousands of Python files at launch. The project announced the change on X on October 18, 2026, and says it is in CUDA nightlies and in official release images from v0.32.0.
