Python function bundles now include precompiled bytecode
Vercel announced that Python function bundles now include precompiled bytecode. Previously, Python functions required bytecode compilation at runtime, which added latency during cold starts. By including precompiled bytecode in the deployment bundle, Vercel eliminates this step, leading to faster function initialization. This improvement directly benefits developers using Python on Vercel's serverless platform, as it reduces the time before a function can handle requests. The change applies to all Python functions deployed on Vercel, with no additional configuration needed from users.
// why it matters
Precompiled bytecode reduces cold start latency for Python serverless functions on Vercel.
