Vercel adds WebSockets for Python Functions

Vercel has introduced WebSocket support for Python Functions, empowering developers to construct real-time capabilities like AI streaming, live chat, and multiplayer collaboration on serverless infrastructure. The update supports both ASGI and WSGI interfaces, ensuring full compatibility with major Python web frameworks such as FastAPI, Django, and Flask.

// ANALYSIS

Bringing WebSockets to serverless Python removes a key architectural bottleneck for developers building real-time AI streaming applications.

–Pushes Python serverless functions beyond traditional stateless HTTP requests into persistent, bidirectional communication.
–Supports both ASGI and WSGI specs, enabling seamless deployment for FastAPI, Flask, and Django applications.
–Significantly simplifies real-time AI application development by keeping the entire stack on Vercel without requiring separate WebSocket servers.

OpenAI open-sources Codex Security CLI

OpenAI has open-sourced Codex Security CLI, a tool designed to help developers discover, validate, and remediate vulnerabilities directly within their local development environment and CI/CD pipelines. By combining local context analysis with AI threat modeling, Codex Security CLI allows engineering teams to scan local repositories, automate security checks in workflows like GitHub Actions, and track security findings over time.
