Python SDK Beta: How the Language of AI Runs Faster and Safer with Fastly

Fastly has introduced a beta release of its Compute Python SDK, allowing developers to run Python code at the network's edge, enhancing speed and security for AI projects and other applications. The SDK cross-compiles standard CPython to execute within isolated WebAssembly sandboxes, supporting popular frameworks like Flask with minimal modifications. Fastly's approach includes memory snapshotting to reduce cold-start delays and maintains Python's dynamic nature while ensuring security through isolated request execution. Although the SDK supports pure Python logic and WASI-compatible extensions, it lacks support for native ML computation frameworks and filesystems. Fastly encourages user feedback and collaboration to refine the SDK as it progresses towards general availability.
